1940s Westinghouse AM/FM Radio Model H-1821

If you have Sams set 50 folder 22, it covers the model H-202 and H-204 (chassis V-2128-3) which is nearly the same radio but with a selenium rectifier.

Thanks I'll take a look and see if I have that one when I get a chance.
What's the best way to clean up and polish Bakelite after cleaning paint splatter off with goo gone?
I'm asking because the Bakelite finish got dulled after I finished cleaning the cabinet.

Unfortunately I don't have set 50 period.

Good news is that my replacement cord should be here tomorrow!
Which means I should be able to power up the unit and see what its current working order is like.

Do you know why these radios would not have their pilot lamp installed? I'm asking because I saw a youtube video of someone restoring one of these radios and that one also was missing its pilot lamp as well.

Was it because it was a nightlight bulb and they didn't want to risk damaging the bakelite cabinet with the bulb?

I use #7 white polishing compound, which I get at Ace.

Picture please :-)

Well I got the replacement cord in the mail the other day and I went to plug in the radio to test it out, and the radio had no hum to it whatsoever (the power supply filter cap can is of the dry electrolytic type like what's in my 1931 Westinghouse, which is still working with its original filter caps in place) but for some reason there was no stations coming in on the radio, nothing on the AM or FM Band and I tested all 6 tubes in this radio and they all tested like brand new, so I'm not sure what's going on with this radio.

Any Ideas as to what could be wrong with this radio?

Below are some pictures of the unit as resquested.

Check B+. If it is low change rectifier, if it is still low after that your lytics are bad. I've worked on easily 200 radios and can tell you that 1 or 2 surviving caps of a type or make is FAR from a confirmation of reliability of parts of the class.
If your B+ is normal and you have no reception inject audio at the grid of the first audio amp stage and see if you get anything at the speaker. If you get reasonably strong audio the problem is in the band switch, RF, converter, IF or detector stages, if you get no audio go over the audio stages. Divide and conquer.

I've changed the rectifier tube out for a known good 35W4 rectifier tube and it still wasn't working.
I'll take the chassis out of the cabinet and check out a few things in the radio's underbelly.

Also one thing I forgot to mention, I was monitoring the current being drawn by this radio using my Kill-A-Watt Meter and the current draw is spot on with what is marked on the back of the radio which is 30 Watts and 0.25 amps, so I'm not sure what's going on with this radio and why I'm not getting any stations in on it even though according to the Kill-A-Watt Meter the radio isn't running abnormally (like my TV is.)
