One  mono tube amplifier as seen in the photos - This did have a PE emblem on it and that in my opinion stands for Precision Electronics - This uses 6GT5 output tubes - One OA2 tube is missing - I have never attempted plugging this amp in to see if it works -  This must be over 50 years old in which case it will probably need to have it's capacitors or something else updated -  I cannot guarantee any part of this amp to be good not even any of it's tubes since I have never tested them  - Selling as a Non working Parts unit - Please examine the photos and judge the condition of this amplifier for yourself  - I have one more that I plan on selling after this one is gone - Dimensions are approx. - 19" x 7-1/2" x 10" - Shipping via Fedex ground with signature
