I was wondering if anyone knows of a book on old school S.S. guitar/bass amps.I am mainly looking for the Sunn,Peavey,Crate"SLM",Kustom,etc.,etc.older stuff with very few early IC's maily single transistor designs.Any ideas or leads?

I got the Kustom lead 3 akrakin.It used a old triodial I forgot I had buried my years ago in the garage,"see it pays to clean it out once in awhile"I found the root cause was a bad 5 watt resistor and 5 watt 12 volt zener.Now to my question,I tried to reform the two 4500 mfd 50 volt, 30+ year old GE large can,screw top terminal caps.No go they are shot.I used 4-2200 mfd 63 volt twist top"tab" to replace them"2 in par.".The orginal caps are the size of a 12 once can of coke"no kidding"exact replacements are $100.00+ each in the Allied catalog.I am worried about the diffence in phyical size"plate area etc."Will my setup holdup?Or any ideas for cheaper replacements?I feel I am over my head on this one,by the way the Kustom has 4 power transistors,TO-3 package"claimed 130 watts"and only 1 IC in the whole amp.Very old school.

I am not a pro or con SS ver. Tube,I am a 55 year old guitar playing rocker.I have more than my share of amps,both tube and ss.I have a Kustom Lead 3 with a 1978 QC label inside the chassis.The P.T. is fired in it.Its a 2 channel with voicing "mixer" for the 2 channels with master volume,130 watt.The thing weights 45 pounds for the head alone.Should I invest in a new P.T. or part the 2 pre-amp,voicing,power amp board?I wonder if anybody would be intrested in parts on the hoof?The boards would be ALOT cheaper to ship than a 45 pound head.Ant ideas or input.
