First things first, if it were me I would just buy it right off the bat. That said...

  1. Reverb tank should be simple pimple. Unless it's some odd setup(which I doubt it is), it would usually be a RCA jack type plug and play. Accutronics has always been my favorite replacement reverb tanks.

  2. Tubes wouldn't be expensive to mess with if you wanted to try others out. I would see what ones they had in there and then just order a couple different brands to see what sounds best to you. A couple [JJ preamp tubes] (https://www.amazon.com/JJ-Electronics-T-12AX7-S-JJ-Electric-Amplifier/dp/B0002M728Y/ref=sr_1_1?ie=UTF8&qid=1541011028&sr=8-1&keywords=jj+12ax7) and [a matched set of EL84 JJ power tubes] (https://www.amazon.com/JJ-Electronics-Amplifier-Tube-T-EL84-JJ-MP/dp/B003FO89CE/ref=sr_1_1?ie=UTF8&qid=1541010458&sr=8-1&keywords=jj+el84+matched+pair) are really cheap and tend to be built well from the years I've been buying them for. I'm thinking only the first two preamp tubes would have anything to do with the tone section as the third one (furthest small tube to the left when looking at the back) could just be the phase inverter and also driving the reverb. I'd have to loom through a schematic first to actually know for sure, though.

  3. Price would be good to me as it's half off new and I'm a cheap bastard that can attempt to fix things if I need to. If it sounds good to you in just replacing a reverb tank and trying out different tubes, tear it up.

    I had no idea of these cheap guys being around and may end up getting the little 5w version for fun around home. How cool.

Being that you've got nothing to compare it with, your best shot is to buy a new power tube (which isn't that expensive, typically), of which I'd recommend a Tung-Sol 6V6GT for the Fender Champion, and toss that in. Unfortunately, you can't compare your tube to another one in the amp because it's just the one, so your best shot is just to retube.

From what you've described, it sounds like a dead power tube. It happens after a while in every amp; tubes die. If it was a pre, you'd still be getting output but it'd sound weak/muddy/off. Feel free to replace that one too if you want, as it might die soon as well. Here's a link to a retube kit.

Hope your amp gets back in action soon!

This is my opinion, so take it as just that:

Are they hard to replace. No. Hell no. At least with a common lightbulb, there's screwing. Pull out. Push in. That's it.

AC15 particular tubes. Can't speak for certain, ain't got her. Just chuck in another set of what, el84s? hold on, googling. edit: indeed, el84s. So, if you're stateside...try:
https://www.amazon.com/Tube-Complement-Vox-AC15-brand/dp/B00AOA6FXC

Not from amazon directly, but you can return it and eat the return shipping cost if it doesn't...alter anything. Or, ask around your buddies, maybe there's a nerd like me that has buckets of tubes lying around.

Match vs. unmatch refers to power section, handy when biasing. I'm an oddball that prefers unmatched tubes in the power section for harmonic effect, trust me, anything you read about here, the effect is going to be quite minimal.

A brief read:
http://www.fenderforum.com/forum.html?db=&topic_number=714229
Expensive tubes worth it? No, not really. You'd see a bigger difference swapping out your speaker, or pickups. Tube changes make for pretty light if any noticeable sounds.

tldr; replace them :P

Nothing fancy just in case someone gets sticky fingers;

Amp
Headphones
Audio Cable
Tube Upgrade

u/maltawind · 2 pointsr/headphones

Re: the heat issue, you could try using tube socket extensions like these or these. They help cool things down a bit, don't affect the sound, and make it easier to extract and attach tubes.

u/kostaricohse · 2 pointsr/GuitarAmps

I advise you to change the tubes in case you've bought a used AC15C1: as example JJ Tube Upgrade Kit For VOX AC15C1 Amps EL84 ECC83S ( https://www.amazon.com/dp/B00VVNIIVS ) or any other alternative tubes. Sound will improve dramatically, especially on Top Boost channel.

u/charleyjacksson · 2 pointsr/Guitar

[I use these for tone](JJ Electronics T-12AT7-JJ Vacuum Tube ECC81 Electric Guitar Power Amplifier https://www.amazon.com/dp/B000UMFQHA?ref=yo_pop_ma_swf)

[And these for power](JJ Electronics T-6L6GC-JJ-MP Vacuum Tube Beam Power AMP Matched Pair https://www.amazon.com/dp/B003X5HE08?ref=yo_pop_ma_swf)

As always, it's subjective. Listen to some sound comparisons on YouTube and stuff.

u/JiBBy23 · 2 pointsr/Guitar

My amp does the same thing, pretty common. Instead of messing around w/ the sockets (dat aint it), hit the note to get the rattle sound. You can use a looper to make this easier. Then use a washcloth (they're hot!) and apply slight pressure to each tube to see which one is ringing the worst and verify which tubes it rings on. Now that you know which tubes are ringing/rattling, you can order the number of tube dampers you want from Amazon!

https://www.amazon.com/Eurotubes-EuroDamper-Damper-Triode-Preamp/dp/B019P7KA1C

They're a lil pricey for what they are but they work to eliminated about 75% of the noise. I'm cheap, so I ghetto-rigged something similar involving toothpicks and rubber bands lol. I'd recommend a damper though :) dont be like me

u/SgtKashim · 1 pointr/Guitar

Sold: A Peavy Vypyr 15 watt amp. I replaced it with a real tube amp. I wouldn't buy this amp again... it was kinda crap.
Bought: A new set of tubes for my amp, plus a set of Seymour Duncan P-Rails.
GAS: Still a PureSalem Woodsoul, but that's not going to happen.

u/Mysterions · 1 pointr/Guitar

I just meant for a Vox. Are they all about the same then?

Something like this would be fine?

u/sumijo · 1 pointr/audiophile

I haven't had the time to open the chassis and verify this schematic for myself (found afterward), but the one I linked to should be the exact same amp. I measured the transformer output voltage a while ago before finding it... now that I think about it, probably improperly (and somehow didn't kill myself).

As for retesting plate voltage, would this work? https://www.amazon.com/dp/B019PAVXPG

It's designed for measuring plate current, but I should be able to use it for voltage by connecting the red probe to a multimeter and covering the black probe... right? It would certainly save me a lot of time opening the amp again.

u/sixstringgtivr6 · 1 pointr/GuitarAmps

Would this be ok to use? https://www.amazon.com/Eurotubes-Bias-Probe-Octal-Tubes/dp/B019PAVXPG I remember seeing a youtube video years ago on biasing that used this. When I was looking into it recently, everyone only said about using a multimeter. I'm assuming I just put it under each tube, power on and adjust. Is there anything else I'm missing or should know about?

I think I see the resistor you are talking about (it looks discolored). Is this something I could and should replace? I'm not too experienced soldering.

u/Nixxuz · 1 pointr/BudgetAudiophile

A tube buffer is OK, but for the real tube sound I'd go, and do go, with a fully tube pre. It's over your budget by $20, but the Little Bear T11 has been very good for me. If I was in your shoes and wanted something for right around the $200 mark, I'd go with the Little Bear T2 and roll out the stock 6N2 tubes with a pair of Genalex Gold Lion 12AX7's.

https://www.amazon.com/Nobsound-Little-Vacuum-Preamplifier-Turntable/dp/B074GXGSNY/ref=sr_1_4?ie=UTF8&qid=1539167685&sr=8-4&keywords=little+bear+t7

https://www.amazon.com/Genalex-Gold-Lion-12AX7-tube/dp/B00CEOPL36/ref=pd_rhf_ee_s_rp_0_5?_encoding=UTF8&pd_rd_i=B00CEOPL36&pd_rd_r=3VVVBFABJ8BG8EDGHM98&pd_rd_w=tkMlx&pd_rd_wg=dT1bK&pf_rd_i=desktop-rhf&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=ba66fe13-e1c6-4bb5-8d37-ef9a637b33d1&pf_rd_r=3VVVBFABJ8BG8EDGHM98&pf_rd_s=desktop-rhf&pf_rd_t=40701&psc=1&refRID=3VVVBFABJ8BG8EDGHM98

This comes to $10 over your budget, but it will give you a great pure tube phono preamp.

For cleaning tube pins I use:

http://www.musicdirect.com/p-1158-caig-vacuum-tube-survival-kit.aspx

Some people don't like liquid cleaners for pins and prefer dry cleaning with a wire brush or similar.

For cleaning tube glass I use a 1/2 distilled water 1/2 isopropyl alcohol mixture with a soft cloth (similar to what people would use on a car). If you do this you need to be really careful not to rub off original tube glass markings.

For tubes I use frequently (and take in and out of boxes) I put them in a different white box (so the original boxes don't get destroyed from constant handling):

http://www.amazon.com/Vacuum-Miniature-Tubes-12AX7-12AT7/dp/B005JEJKJY/ref=sr_1_1?ie=UTF8&qid=1406312990&sr=8-1&keywords=vacuum+tube+box

I'll write tube and test information on a sticky that goes on one of the white box flaps. I then store all tubes in a plastic container and keep the original boxes separate until I need them again (mainly when I go to sell)

For handling (plugging into amplifiers, removing from boxes, etc) I try not to touch the glass if possible to keep the oils from my skin off the glass. I usually handle by tube base or use a cloth.

u/ldegs · 1 pointr/Guitar

An attenuator would work. Something like this. Link to one on amazon . I don't know anything about that one, I just did a quick amazon search for it and its the first one that popped up.

u/dcoolidge · 1 pointr/headphones

Hi, I have the Bravo v3 and was wondering if there is a better tube for this thing. Any suggestions?

edit: Found two that I may want to try. Electro Harmonix or Sovtek...

u/BananasApeUnicorn · 1 pointr/headphones

The Bravo seems decent but I just don't trust cheap Chinese tube amps, especially when they don't post full measurements (I wonder what they're trying to hide?)

But, under $114, on Amazon, there isn't really much in choices. The Bravo plus a warm sounding tube, like this one, will fit the bill.

I also would recommend this. It offers more flexibility because you change tubes and opamps to mod your sound. You can also adjust gain with it unlike the Ocean.


u/Neckbeard_Prime · 1 pointr/GuitarAmps

Heh, fair enough. Switches shouldn't set you back more than a few bucks apiece if you replace them yourself, and then go from there.

What tubes are in there? Six 6L6GC? Looks like about $130 on Amazon if you go with JJs, but they don't have a set of six matched tubes. The old ones may still have plenty of life left in them anyway.

Electrolytic capacitors are the other "wear" item to watch out for. When you do the teardown for the switch replacement, keep an eye out for any leaky caps -- they will let the magic smoke out. Having never worked with a Twin, I'm curious if it has the same giant "canister" style multi-stage capacitor that my Princeton and Bassman did. Those are safe to replace with multiple plain old electrolytic caps, but finding a secure place to put a board full of capacitors can be "fun." At least the replacement caps were cheap.

If the speakers turn out to be trashed, Weber makes some niiiiice replacements that play well with a clean or pedal-based setup. Looks like that will set you back about $228 plus shipping, if you need them.

So, somewhere between $30 and the black market value of a slightly used human kidney. Haha. As for whether it's worth it... Twins are, hands down, the best amps you can get for sheer clean tone -- AMAZING studio amps -- but max volume on the thing may set off car alarms all the way up and down the block. Maybe you'll need to play a set on an airport tarmac?

u/elihu · 1 pointr/Guitar

I don't know about the other amps in the page you linked, but the Behringer AC108 is a lot of fun. It does a good solid state clean sound and a good tube-preamp distortion sound. I swapped out the stock 12ax7 tube with one of these: https://www.amazon.com/JJ-Electronics-T-12AX7-S-JJ-Electric-Amplifier/dp/B0002M728Y If you like how the stock tube distortion sounds, though, there's no need to upgrade.

u/chewbawacca · 1 pointr/Bass

Hey guys, literally got a call the other day to get the band back together! I'm super excited, but I haven't touched my gear in about 7 years. I flipped on my ADA MB-1 and I'm not getting any sound out of the tube stage on the preamps. I believe these use 12AX7A tubes, but can I use a set of 12AX7 tubes like this. I know nothing (or have just forgotten at this point what I need to replace these with. Thanks, I'm going to be back here alot if we start playing on the regular!

u/ThomasdeChevigny · 1 pointr/GuitarAmps

Very complete answer, thanks man!
I'll order a T-12AX7. Is this one okay or are there subtleties about ''Medium gain'' that I should look into?

u/Bungie · 1 pointr/vinyl

I have not had to replace the tube on it. I've had it for almost three years and I listen to my records roughly 2-3 hours a day...maybe 3-4 days a week. The VP130 doesn't have an on/off switch, but I leave mine plugged in 24/7. So, my tube is always "hot" and has been for 3 years.

The one that comes with it sounds great to my ears, but if you ever need to replace it, I think you can use one like this fairly cheap:
