MV55 Please Help!

Post by mike.d »

Unfortunately Previous user made changes to the replacement Tube 12AX7 the Soviet 6s3p
[/img]Incredibly terrible damage both the scheme and the sound amplifier.
Can provide circuit and the circuit board to return to the original state for 12AX7.
Do changes in the power supply circuit 12AX7 whether this factory management.
I really hope to help.

Welcome to CJO. It's always tough with these kinds of modifications but if you want to restore the unit to it's original state you are going to have to pull the schematics (which we have in our database) and go through and compare that to the current state.
