Vintage Tube Amp

Vintage Zenith Stereo Hi-Fi 6BQ5 Tube Amplifier Model 4K21 – See Video. We tested a turntable with it, and it was also working. We tested the 6BQ5 tubes with a tube tester, and both tested below the minimum good value of 50 (tested at 46 and 44) and had shorts. The 12AX7 was tested right at the minimum value of 32. We did not test the 5Y3. The last photo of the tube diagram was from the console it came from and is not included, for reference only. Cosmetically, it is in good condition with light wear and some marks/stains on the face. The amplifier may need updating or repair, even though it was functional, due to its age. Please see all the photos. It has Stancor Power Transformer 95-1953, 20VAC, 50/60 Cycles, 1386226. It has 2 output transformers by Ensign Coil (95-1957-AR, 1726218). The face measures 13-1/8 x 6. The chassis measures 12 x 8 x 6.25. It weighs 12 lbs. If you have any concerns or issues with your order, please reach out to us directly before leaving negative or neutral feedback.
