Hi Terry,
There's plenty of volume !!
I have installed new caps in the Bakelite case, a .015uF for #25 & and a .001uF for cap # 21.
Seem's I have just very weak reception.
When I hook up the RF signal generator to the antenna, set to a low level signal I have no issue receiving the signal at various frequencies.
For example, set the generator to 1300KC, change the tuner to 1300KC, or set the generator to 600KC, change the tuner to 600KC, no problem hearing the 400Hz tone. Looking on the scope at the speaker, it's a nice sine wave. And it's loud.
I changed R15 from 4M to 2M, it didn't help to bring in any stations, but it did make the radio even louder!
When I first started working on the radio I found the 6.45 ohm coil that is in series with C5 & R8 that connects to the cathode of the Det/ Osc open. I had found the wire from that coil was broken, so I found where it was open where it exited the coil and soldered it to the lug on the coil where the wire to cathode connects.
I replaced the incorrect 44 tube that was in the radio when I got it with a 36.
The only station that comes in is a country station from Carson City, but it has a lot of noise and is kinda garbled.
I just bought the AM transmitter kit from tubesandmore, when it comes, it will be interesting to see how well the radio picks up the signal from it.
This new hobby is getting expensive.
Just spent $80.00 on lacquer toner, sanding sealer, and semigloss clear for this cabinet. And some how I have ended up with 7 radios that all need to be refurbished. Including a Philco 14L.
Thanks for your help
