Years ago i bought a 1987 RI off Hank Sherman from Mercyful Fate and i got the brilliant idea to upgrade it with a metroamps turret/ptp kit.. After board assembly i cut out the old china pcb and threw it in the bin, and realized i didn't know jack about amps.

Years have passed, (i study electrical engineering now), and feel more confident tinkering about inside a tube amp, and now i want to restore the amp.
Question:
I would like to "restore/upgrade" the amp to org. 1987 specs (or close to), is that possible with the tranformers already in the amp now?
any thoughts or comments are appreciated!

cheers from Denmark
