Tuner not working on 46-420 code 121
#10

OK I set up an RCA 65X-1 with a known good tuner next to the Hippo.

I turned on the Hippo and got the dial as close as I could get to AM 700. I turned on the 65X-1 and turned the dial to what I thought would be 1100 (the dial string is broken in that one and the chassis is out of the case sitting next to the Hippo).

There was absolutely nothing received from the Hippo no matter where I tuned the 65X-1 and I turned off the Hippo which had no effect. The 65X-1 picks up WLW at 700 and leaves it behind when dialing past so I know its a good tuner.

So at this point it seems like the oscillator is not working in the Hippo.

One other note: I snipped out what I thought was an old wave trap wax cap when recapping. This contained C14 and L1. Think I should put that back in the circuit to see it it was the cause of all this evil?
