Hi Folks, recently I bought a Studio Pro 112 Trans tube amplifier site unseen, but when received it had a low hum and now other sound when powered on. I have check the power caps , but I think the power out IC is stuffed. I noticed there was an additional speaker socket on the back of the instrument which means an external speaker was connected in parallel with the internal Blue marvel and severely load the IC and caused damaged.
Is there a schematic for the is version of the Studio Pro 112? there several around but have discrete output transistors.
Thanks
