Problem solved!!! Thank you guys for all your help and it happened to be a little resister we missed plus the bias was off. Once again thank you very much for your help y’all have a wonderful

update. We have switched out the capacitors and a couple of resistors that were burned up. Now on power up the green light comes on and The four red LEDs light up on the motherboard. However as soon as we Push any kind of volume through it it goes into protective mode. Or the red overload LED comes ...

Thank you Jason your help is much appreciated

Awesome guys. I will let you know how it goes I really appreciate your help guys thank you. And the other two, fatter sized electrolitic's should be replaced? and if so should I replace with higher voltage limit Chesley Shapiro

Can anybody tell me where I can find these resistors for sale.
22, 33, 68 ohm, 1/4 watt, fusible resistors?

Awesome thanks for the advice I will change out the caps. Also a little update on some information I’m looking for bias voltages on driver and power transistors. Thanks again for the help Chesley Shapiro

Good evening fellas I’m hoping somebody can help me out today after learning that it is pretty much impossible to get the electrical schematic for this a.m. I’m wondering if anybody here on this form can help? On my 275 I had a blown right channel. Static he sound in very low volume out of that righ...
