Tuner not working on 46-420 code 121
#8

Fantastic troubleshooting ideas!

All of you.

There were no shield cans over the tubes themselves - only the IF coils.

I'm wondering if while I was tuning the coils I might have pushed down a little hard on the screw and part of the coil inside (maybe the 1st IF) is now touching the aluminum cover.

I'll also try another set next to the Hippo and try that higher frequency test.

I'll be back in touch.

Thanks to you all.
