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.
