hi guys,
I bought a used 2550 recently, which sounds awesome btw but the clean channel is very low output compared to the dirty channel - in fact the whole amp is not as loud as I thought it would be. Does anyone have any idea what may be the problem? Could it be a pre-amp valve/ tube?
Cheers, Jim

Hi guys,
I am just about to pull the plug on a used Nik-built 2550 and just wondered a few things:
1. I already have a JCM900 with the diode clipping - Is this amp a straight through Valve amp with the option to add diode clipping with the switch?
2. How heavy can the distorted sound go? - I am a classic rocker but just wondered.
3. How easy is it to bias? I know it has test points on the back but is it justa case of testing it and adjusting the bias pot? (I have biased my other amps successfully)
Cheers, Jim
