Seems like it's the cathode resistor and the cathode bypass cap of the power tubes(ECL82).

Here is a how to about posting pictures: https://el34world.com/Forum/index.php?topic=14521.0

The components circled in the image are in the schematic, the 200(210) ohms resistor and 50uF capacitor in the following picture. Assuming the provided schem is the right one.

Theory is when everyone knows everything but nothing works, practice is when stuff works but nobody knows why !!!

see pic...

A long time ago the forum software had a glitch that would randomly cause all the text you had typed into your reply to disappear when you added an attachment. So that warning was added as a reminder to copy all the text you had just typed into the reply box to the clipboard just in case this happened to you. Then you could just paste the text back into the blank reply box. I believe that software glitch has long been fixed.

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thanks explains pic problem.

Yeah your right I was counting pins back to front runs to pin 2 not 7...
While chasing this board out can anybody tell me what these two pea sized resistors are, they look glassy, one runs to treble/on/off switch.

Those are polystyrene caps.
