OK, pin 6=187vdc, 7=9.3vdc, another set of tubes from another IF are
exactly the same, I've got about 2 more tube sets, but the 6AK6's both
are marked low gain or uphonics. I'll have to pull the unit to check the
coil. Both those bypass caps were replaced last year or so with new styles.
This thing sounded fine OTA, but I was into it because of the erratic
gain at T502 and that seems to have gone. I almost had the thing sold
for good money. It looks good and has all the parts and both meters work
right, at least last summer.
