Aleph J illustrated build guide

I am curious about R15 in one of the pictures in post #10,235.

R15 is shown as a Dale RN60D with what appeared to be 2207J written on it. I am puzzled by that as from my understanding of the RN60D numbering format, 1k resistance should be specified as 1001 plus the tolerance code.

Just wondering whether the other half of the circuit is working.

Getting back to the issue at hand, if the resistors and pot checked out, then it may be that the transistor is faulty and shorting, allowing current to flow through it regardless of the Vbe. You can try measuring the resistance between collector and emitter. In the circuit that would be in parallel with R27 pot, R15, and R16. If the transistor has a short, the resistance would measure low, and adjusting the pot probably would not change the measurement much. However, removing the transistor from the board to check it will give a definitive answer.
 
Ok I am just lost and frustrated. I checked the voltage across r8 of 8.4v, so about 8.4mA is flowing through that current source. Both gates of Q1a/b are at ground so I assume the current is dividing equally. The voltage across r7 is 4.8v, and adjusting r7 has no impact on the voltage. How is it possible that the voltage doesn’t change when I adjust the resistance of the pot ?
 
R7 sets the DC offset.... I thought you couldn't change the bias (locked at 550mV across each of the R16/17/18/19)..??
with the amp plugged directly into the wall the voltage across r18 increases to 550mv

Do you also have a problem with DC offset (unable to trim it)??

If DC parameters look okay, apply a very low pp 1kHz sinewave at the front and look for the amplified, undistorted (unclipped) sinewave signal at the output - no load. That will further help with fault finding.

Here's the sheet I prepared earlier... I already removed the confusing resistors and links... you may find it useful.

Basically both pots don’t seem to do anything. All 4 mosfets are drawing about 1.25A which I am concerned will burn out my transformer. The transformer already has a buzz to it when I turn the power supply on. I measured all the voltages in the amp and nothing stands out as wrong. It’s just the bias current is too high and I cannot reduce it. The offset is about 100mv on the output and I cannot adjust that either. I have no idea where else to look other than one of the active devices might be burned out ?
