Hi Phil,
The chassis ground is attached and I have checked the continuity of the pots and they are grounded to the chassis.

R1 is not showing a continuity to the chassis - is that as expected?

The test points for 7 and 8 are a long way off - does this also suggest a preamp issue?

When shorting q7, should I wire across joining the three legs of the fet?

Thanks Enzo,
Yes, the amp powered on ok without the speaker (using the lightbulb limiter) and did not blow the fuse.

When I connected the speaker the noise was apparent but did not blow the fuse before I turned it off.  The lightbulb remained at a dim glow throughout.

I will check for dc on the output and let you know.
