Additional Tone Tweakers Listings, also on Reverb

In addition to necessary repairs, he did the following work to this unit:
Replaced all electrolytic capacitors.
Replaced all 4051 CMOS chips.
Removed all keys and cleaned key bed.
Removed plastic screws in power supply section and installed isolate washer and metal screws.
Replaced some IC sockets.
Added ground wire to reduce noise.
Cleaned and lubed faders, switches, key contacts.
Installed new battery.
An interesting note our tech added was that the serial number badge on the outside of the unit says sn85121x but inside says 79078x, no idea why. This JP4 is now working perfectly and sounding incredible."
