ruffrecords said:I just noticed you have a 620 ohm resistor across the grid of the EF86. The probably explains your low gain. Do you have the T157 input transformer fitted?? If you do then it needs loading with a much higher resistance, like 150K or more.

I ended up changing that the other day because I had suspicions that it would drop gain (and it did). The schematic shows a 1M and I think I originally put the 620R in there to match with the other channels gain wise. I put a 1M back in there and it got better.
