I think I may be done messing with this amp. I replaced just one of the pots and its made no difference. Now when plugged in its not even getting warm. so maybe other transistors are bad. like the Q7, Q8, Q9, Q10.
Not sure I'll have to open them up and take some pics. They came to me by the way of a long term friend of mine. He got them from someone he knows very well and had them in storage for many years. They came from Jimi Hendrix's manager's house a long long time ago. If they could only talk! My...
Does anyone know what this knob does? I don't see it in any of the pics I've researched on the web and it's not labeled. Its the one below the inputs on the right. It has 6 positions. All the knobs match so I don't think it was added but the knobs could have been changed. I don't know why you...
I have some leads with alligator clips on the ends. So I replaced the transistors and at least the readings are much closer at 67.8mV left, 46.2 mV right. Better than the 206mV left, 60mV right. The pots are still not adjusting the bias so I'm going to order new ones and the 2n5088 transistors.
I only picked up the the transes for test purposes since the only place by me has the NTE brand. I will be just connecting them long enough to to see if I can adjust the bias. I did not get the pots because again they would be NTE but the pots are working 0-5K. I know that doesn't always mean...
