Vintage Tube Amp

Presenting a Vintage 1960-63 Vintage Lafayette 250A Stereo Tube Integrated Amplifier. Power about 18-20 wpc. Nice set of tubes on board. (4) EL86 Lafayette branded Amperex Holland / Amperex. (2) Lafayette zbranded 7199 USA probably RCA. (2) GE JAN 12AX7WA (military grade). This amplifier was made in a a era when Lafayette was Made in USA. Check out the cool TV feet on this. Unfortunately its missing one outer Bass Control knob. All controls and switches were cleaned wirk and are quiet. We used a variac to power it up over many hours. It passes a clean signal with no hum playing a CD plugges in the AUX input. Here is a problem. The three 12AX7s are not lighting up. So they are not getting the heater voltage. Possibly a cold connection somewhere. Because of this the problen dual concentric Bass / Treble controls are not responding. At first they worked then stopped after awhile. Its wild how this amp is designed in this manner. The amp will still pass a good signal without these tubes functioning. As with most integrated amp designs. IF these tubes were lit you would get no signal. The volume controls work fine. The volume control is dual concentric. So there are 2 volume controls L & R in one knob seperated so you may control the left and right channels separately or both together. This takes the place of a balance control. There is a STEREO / MONO blend control knob. Which also acts as a ON/ Off when turned fully to the left. Turning far left is STEREO. Turning far right is MONO. Everything inbetween that changes the blend from Stereo to Mono. There is a phase switch. There are also two other switches to contro channell switching that allows you to switch and choose the signal to each amp channel A or B signal on the Left and Right Channel seperately. Another interesting design feature. Well thats about it. With a little work yiu will have a real fine well built vintage Stereo integrated amplifier.
