Vintage Tube Amp

Knobs don’t appear to be original.

This Vintage Untested Mono Integrated Tube Amplifier was made by Calbest of L. A CA, for High-Fidelity Unlimited. It does not come with tubes, but uses 1x 5y3 GT, 3x ECC83, 2x EL 84. The Model Number is 7615 and the Serial Number is A 151224. There seems to be a link between HFU and the Ampex Corp. In some of their consumer audio products. I have seen at least once, 2 exact stereo units, one branded HFU and one branded Ampex. All the controls and functions are shown in the photos. The case is solid wood (no pressed wood or plywood). There is one thing to note condition wise, the front wood section is cracked on the left side of the control panel. You can see this a Photo. It will not affect any function. I have another Tube amplifier, a Harman Kardon, also listed. Please look carefully at the pictures as they are an important part of the description. I desire to keep my feedback as high as possible.

Nice working vintage Knight KG-240 stereo tube amp. Had my tech put a new ac cord on it, but everything appears to be original. It uses a clever design that utilizes 4x6GW8 tubes for the line amp, tone amp, phase inverters and output tubes!
