does anyone know where the mixer grid test point is on a ctc 11 tuner? thanks.

The 6EA8 mixer - pin 2 grid test point is at L8, see lower right diagram, left hand bubble 1 and 6 point to it on one of the switch wafers.

Appears to NOT be a feed thru, so it needs the cover off to access it. Hope you are successful.

Thanks. The ETF doesnt have a scan of the factory service manual. maybe a thought to scan it for them.

That is a good idea. I only have the 10, 11, 12 and 16. So Ill see what they need.
