K100C-8 Schematic Needed [message #11870] Fri, 18 September 2009 17:25   HipKitty Messages: 9 Registered: September 2009 Location: Nashville, TN Junior Member Possibly some one has the schematic for a K100C-8....if you do, please email it to me. If there are any tech notes available for that model as well, it would be greatly appreciated as well. I had one come in and thought I had a line on a schematic for this, but what got sent wasn't what I needed. Thanks! Neal Report message to a moderator

What is the problem you have with the amp? Report message to a moderator

It had a loud hum until I replaced the large filter caps, so now it's just the left side that's out. In doing the initial circuit test, it looks like the first transistor is blown since no signal goes past it. I need to verify that transistor and see what the circuit looks like downstream.

If its the first transistor that test bad just replace it, its a very common type(2n2906 small signal NPN type. If you do not have one get to Radio shack and you can pick up a pack of 4 or 5 small signal NPN audio types for under five dollars. Report message to a moderator

The transistor that's in there in the first and second position is an HEP-S0015. Do you have the schematics? Report message to a moderator

I started on testing points in the circuit and found no dc voltage at the base of the first transistor....unfortunately, the bias resistor value that's printed on the case of the resistor is unreadable, but reads a value...I'd like to verify that bias resistor.
