New amplifiers, interesting repairs and other musings
I have been doing these Pro Jr handwired conversions now for several years, and I have done quite a number of them. The original Pro Jr is a nice little package but is a one trick pony and not an inspiring one at that. I simply remove entirely the original PCB and the only thing I reuse is the chassis and power transformer. I convert to 6v6 power tubes, build a Turret board, install a USA made output transformer with 4,8,16 ohm outputs, install real 24 mm pots and switchcraft jacks, a real fuseholder, carefully wire up the circuitry and can optionally install a variable wattage control to turn it into the utmost in tone and practicality.
