Reddit reviews Honeytek A6013L Capacitor Tester

The Fluke 15B+'s finest resolution is 10pF. Which means that you might not be able to tell the difference between a 6pF and a 14pF capacitor. The only time I've see this as an issue is when dealing with crystal oscillator circuits, but I'm sure there are other things. If that's good enough for you, you should get it.

I've never heard a single bad word about Fluke meters.

As for links, here's one. This capacitance meter claims accuracy of 1pF, +/- .5% in the 200pF range. I've never used it, so I can't vouch for it, but it's just one of many, and this one is only $17.

I see no problems with that meter for general use. I have an earlier model of that meter (Fluke 12B) that I keep on my bench at home for double checking resistor values. You might want to consider an ESR meter for checking capacitors. Here is a cheap one with good reviews: http://www.amazon.com/Honeytek-A6013L-Capacitor-Tester/dp/B0036FQ3FW

Well, it was likely an issue with the power circuitry. At least, that is most likely the culprit. The filtering caps in there get hammered a good bit. You will need to get a cap tester. Another not so technical test is to see if the tops of any of your caps are bulging. This typically means they are failing. Once you find the bad one(s) write down the voltage and capacitance then either order online (I use digikey.com a lot) or go to radio shack or something.

Have you ever soldered before? If not, you are going to need a decent soldering iron, some solder, and some desoldering wick. The wick will remove the solder holding in the current caps. This allows them to be freed. Before removing make note which hole the negative lead is in (electrolytic caps are polarized) so if you reverse it they will go pop when you turn it back on. Once your new caps are properly positioned go ahead and solder them in. Then sit back and pat yourself on the back for saving a shitload of money.

Sounds complicated, but it is actually pretty simple to do.

Get yourself one of these, cheap but effective:

It won't tell you ESR though. For best performance, you should change all the electrolytics in the amp. Don't re-cap the AM or FM sections! Without proper equipment and expertise, you won't be able to get the radio aligned again.

As /u/pigpen said, do not count on visual inspection. Caps often fail without any change in appearance.
