I assume this amp was an aftermarket and is not prone to catching fires? lol
that amp is from the early days of eD, commonly referred to an LT350. those are the amps that most parts for it are now obsolete. and at the age of that amp, i would not expect it to last very much longer.
unfortunately, because of the lack of parts availability, once it breaks, there is not much of a chance it can be fixed.
i still take LT200, LT300, and LT500's in because the parts are still used in modern amps and still available. but the older Kiega based LT200 with the big heatsink, LT350 and LT550 have no parts anymore.
so, if it ever breaks, go shopping for replacement amps.
the modern LT500's are the ones that some of them do a flameout... thats because one of the capacitors used that burns is a Chinese cap with questionable specs. the fix is to replace it with a quality non-Chinese cap of the same value, and all works well. this problem is not exclusive to eD amps though... many of the amps i service of many brands have the same problem. thats the cost of buying Chinese amps though. you get what you pay for.
