hey guys
I have a 907 rp
it is suppose to be wireless .
but I don't see any wire inside like others have inside
I replaced caps but duhh I noticed this one how do I find out what it is
says 30-2202 or 30-2292 I checked it`s dead no value at all
also their are connectors # 1 and 2 and red and black
has a radio/ phono switch tested both no power and used pm speaker nothing
I should hear some thing around 55.1 for wireless
sorry but their is no schematic for it
Some day, and that day may never come, I will call upon you to do a service for me. But until that day, accept this justice as a gift

I found a 30-2292 in the '36 parts catalog. It's listed as a 12mfd @450v. Didn't list the 30-2022. Where is it connect??
> used pm speaker nothing
Not surprising it only makes rf no audio.
Measure the voltage from pin 8 of the 6X5 to chassis. Should see 150-200vdc.

figure out what all those squiggly meant.

Ok if it's on pin 8 of the 6J5 the voltage is low there like <20v. Doesn't require a 450v unit. The high voltage is working so let have a look at pin 3 of the 6J5, pin 3 of the 6K7 and pin 4 of the 6K7. All of these should have some hv present. Would check the oscillator coil for continuity. It probably has 4 connections with 2 winding so two pairs should have continuity.

Voltages look good and there where their suppose to be.
The coil, is it connected to the 6K7 or the 6J5?? To me it
would make sense to be connected to the 6K7. Just wanted
to check. What's the voltage on the 6K7 cap? Should a
little -.
We also don't know what frequency it's tuned to, it may
be working but your not listening for it @ the frequency
it's transmitting on.
Happy hunting!!

6k7 is dead zero with or with cap removed
nothing on wire or tube
did get very low sound at 944 very little adjustment 944 to 970
I know cart is bad used 2 known good ones still very low sound
is their some place I can connect a wire for antenna
thanks sam

Would look for a connection from the coil over to one of screw terminals on the bottom. It also could be a connection from the coil thru a small cap to one of the screw terminals.
