Great sounding BassMaster! It's been serviced. New under chassis filter caps. All electrolytic capacitors has been replaced for long term usage. 3 prong power cord. Added bias pot for easy changing power tubes. New bias rectifier diode, ultrafast 3 amp B+ rectifier diodes. Cleaned pots, switches... The date codes of the parts are from 1968 and 1969, although one of the websites says that the serial number is from 1970. The two original can capacitors are reformed and checked, and they are still in good working condition. If you prefer the original filter caps, you can use those two can caps. Some scratches, digs, shrinkage on tolex and front face panel. The plastic cover of the handle are cracked. Thank you for looking!
