Hi everyone,
I am new here, thanks for admitting me. I reach out this forum while I was searching for a solution to my solid state amp problem. I own an old Trace Elliot SuperTramp 80W, the one with just one speaker and no valves in the preamp section. I was very happy with its clean and distortion sounds, very good even adding distortion pedals in front, but suddenly it started to sound very low. I think it had some problem before because before this I noticed it was very noisy even without anything plugged. It had a continuous hiss (more than usual or at least that I remember). So I decided to open it and verify if there was any dust or ground problem (it is an amp from 1996) but none seemed obvious. I closed it and started to play normal, but then suddenly it started to sound very very low. I tested bypassing the preamp plugging directly my guitar to the return plug and it works fine, hence it seems to be the preamp section. In fact the problem affects both channels (clean and dist/boost). I am not good at electronic, I just play guitar ;P, but a very good friend of mine can help me if you give me some tips. I have the electronics scheme and maybe the problem is at the beginning of the sound chain or right after before it is given to the poweramp section. Can you please help me finding the source of the problem or at least give me some tips on how can I find it, what can I test or verify?. I haven't seen any damaged component or at least I wasn't able to recognise any problem visually.
Many Thanks in Advance,
Javier R.
