I am selling this amp for my sister and she is the one who had them serviced, What was changed 1) 8' power cord with new grounded plug. 2) 5 new caps. 3) 1 ecc 83 or 12ax7 tube. the main driver tubes were ok. Tech brought the amp up with a variac very slow and then tested. Upon pic up tech stated that he plugged it in to speaker and played through it and it worked very well, he also sprayed all the pots and switches out and that all cleaned up great and no scratchiness was present, and also set the bias to spec so it should be good to go for another 50 years. I will not ship this amp outside of the lower 48 states. weight is around 32 pounds so shipping will be costly, it will be packed very well and will arrive safe that I will guarantee cause I will pack it. Thanks for looking and happy bidding.
