Rockerverb 50 combo MK I - how to remove head and bias
Posted: Thu Jul 27, 2017 1:39 am
Picked up a used RV50 and absolutely love it! I wanted to put fresh power tubes in the amp because I don't know how old the current ones are.
How do I access the power tubes in Rockerverb 50 combo MK I for replacement and biasing?? I am questioning the best way to get the head unit out. Do I need to loosen the blue or green screws in the photo? I would think green, but mine are stripped (picked it up used :/ ) If I remove blue ones, head will come loose, but I won't be able to get it out the small opening or pull it up out of the top.
Also, does anyone have a biasing procedure for this amp? I have read around and watched a few videos for other amps, but haven't found a procedure specific to this amp. Does anyone have a photo of the inside of the head showing the bias potentiometers? I have tube bias meter and replacement tubes already.
