Hi all,
Just signed up for the forum.
I realize that this forum is primarily Tuck 'n Roll ( I used to have a Tuck 'n Roll head, last I heard it was in Vancouver ) but my question today for those wiser than me regards a Kustom III Lead.
It is all original, and still working after a fashion.
All the electrolytic caps will be replaced which should help to preserve it's operating status for a good many more years.
The question I have regards one resistor on the PC 5065 rev 2 board.
The second from the right 1/4 watt brown bodied resistor that obviously was overheated.
Does anyone have the schematic / layout info on this board in this revision?
Can anyone tell me what the value of this resistor is supposed to be?
Best regards,
Lou

I have a III-L head, but I don't know if it is the same version that you have. I will take a look and see what I can find out.
Edit: I just checked and I have a rev. 1 board. Tell me what resistor you are talking about and I'll see what I mine is. The second from the right, but what edge of the board?

That is why that Fender amp is on the do not repair list. They are made so cheaply that it is cheaper to replace them than pay for someone to fix them.
The worse case on those amps is when the pots crack at the wafer and the leads stay soldered solidly to the board. Replacing all of those pots is really not worth the trouble.
Kustom amps were built to last and to be road worthy for the working musician. That's why they used to come with a lifetime warranty.
And by the way, Kustom pots are also soldered directly to the pc board as well.

A good friend of mine owns a local music school where he teaches guitar and drums and other folks teach other instruments and voice.
Quite a few times the keyboard teacher as plugged into one of the two little SS Fender 1-8" amps that he has for guitar use and blown them up and if it where not for my vacuum desoldering tool to get the 14 pin output IC pack out and replaced the only other way I would even waste time touching these amps would be if it needed a reverb pan, that's it!!

Great new to hear!
Note that on these metal face amps the 2 input jacks for each channel are a different level of gain, not tone as on the non metal face Kustom amps.
Each jack has a built in shorting switch in it as many amps do and if they are clean will not add any hum , especially if the volume is down, reverb will always add some level of hum on most any amp that has the reverb pan mounted less than 8 to 10 inches away from the power transformer!
