I'm just currently in the process of fixing a Fender Hot Rod Deluxe guitar amp for a friend of mine, the complaint was that it seemed to stop working at random times, although the Valve heaters would light up, I did some googling on the internet and managed to find some useful info on what the cause of the problem could be, I had a look inside and managed to find one cap, a 47uF/500V DC Electrolytic, which appeared to have leaked some of it's electrolyte, so, I needed to de-solder and replace it, Jaycar Electronics only stock a 47uF/450V DC cap in their parts inventory, but, they also stocked a 100uF/400V DC cap too, so, I bought two of them, two 220k/ 5% 1Watt resistors, and two 470 Ohm / 5 Watt Ceramic resistors, which I will use as replacements for two 470 Ohm 5 Watt resistors that are soldered to the PCB, they are part of the power supply that supply power to the channel switching, here's what the faulty cap looks like:
I tried to get a clear pic of it, but this is the best I could manage, anyway, notice that light green colour where the lead goes into the cap?, that's the electrolyte that leaked out of the cap.
A word of warning, do not try to fix a Valve guitar amp yourself, unless you are absolutely sure you know what you are doing, and know how to safely work on them, you can seriously injure yourself, or worse, end up dead if you make a mistake.
