Sorry, you're right, I'm jumping around. Too many things going on at once.

Let me get that info for you on the scope.

In the meantime, I'm investigating another route on the radio. I realize I've been reading the schematic and chassis wrong. C10 may be my issue.

C10 looks like a resistor, but it's a cap on the schematic. It's listed as 100 mmfd (which I understand is pf). I'm measuring it as .5nf, which doesn't appear to match up.

I've ordered some 100pf capacitors and will see if replacing that brings my signal back. It's moving from the tuning cap to pin1 of my 12BE6.

While I'm waiting on that, let me get more info on my signal generator. I'm using one of these little kit oscilloscopes: https://reference.digilentinc.com/re...iscovery/start

It's basically a 0 feature, simple scope. I technically have a slightly more advanced heathkit scope, but it's unrestored and untested so I'd need to tackle that before I could rely on its readings.
