6 FAQs about [Are solid state power amps repairable]

What is a solid-state guitar amp?

In the case of era guitar amps“solid-state” boils down to ordinary bipolar transistors, and the odd 741 op-amp - FET's and Darlington “super-transistors” had yet to make any impact. PNP transistors also still tended to be a bit fragile, so the majority of amps are one arrangement; NPN quasi-comp's.

Can a transistor amp be repaired without fireworks?

In many respects it is a bloody big op-amp on steroids, capable of ripping its ownarms off. If only one of those devices is faulty there is a very high chance of galloping silicon cancer when power is applied.

Do valve amps have DC coupling?

In valve amps we very rarely find DC coupling and only have to cope with AC instability, but DC coupling between stages is very common throughout solid-state amps, both pre and main amps. So any fault that throws off the DC conditions tends to be reflected pretty drastically around the loop.
