Not shown in the previous post is the amplifier/power supply. Here it is and disassembly has begun in preparation for re-chroming. Notice the twist lock electrolytics. These are dual 30 mfd at 500 volts. By 1940, capacitors certainly had shrunk from what they were a couple of short years earlier.

Great radios. I have the E.H Scott all wave 23 I restored last year. Very labor intensive.
It's good you can still find a place to get the chassis chromed. That will be a very nice radio when your done.
Congrats.

Wow, a lot of work there. But the end result will be well worth it.
I need to do the same to my McMurdo Silver MP VI power supply.

Nice radio! I really like the dual eye tubes. Looks like the radio is staring at you while listening in a darkened room! Take care, Gary

Night Mare.
38-690 looks like a walk in the park.

A challenge to be sure! Don't know about the Night Mare part. Love it! Just wait till I get into the tuner. There's almost 30 tubes on that thing!

It's a forest. One could get lost in it. 30 tubes. Yikes. Are you sure at least 10 of them are not there just to look god?

Some do accomplish a purpose of questionable value, especially in this day and age.

24 tube tuner, 6 tube amp/pwr supply as I recall . That's a very nice looking cabinet too. I will be interested to see your posts.I was able to keep one from going out to the trash a couple of years ago .Long story there. Mine came to stay with no amp/pwr supply and even ratty ones are more $ then I want to spend.

The pre FM Philharmonics were 30 tubes. they included an audio expander and a scratch filter for the phono input. This one has the early FM band. 27 tubes on the tuner, 6 on the amp/PS. There is no audio expander as they needed the tube space for the FM section. As I said, the FM is the old 42-50 mhz frequency range. I just purchased a TV tuner "subber". These were a piece of test equipment that substituted for the TV tuner for test purposes. With a few modifications they can be made to convert the modern FM band into the old band. It takes 3 ranges to do that since the old band is only 8 mhz wide.

I stand corrected and learned something new today.
Thanks

I'd be interested to see how you make those tuners to work. I read about it when I was restoring my Zenith Spinet.
i am still thinking of making it receive modern FM. It should sound very nicely.
And your radio....it should sound exceptional on FM.
