I should've have known, as the set has a speaker grill. :yes:
I wonder how many of those strange tubes used in the sweep and HV are available. I see, they also used their favorite 5X4G's in the LV power supply.

Only the small 6" table set didn't have audio circuits installed. The 1938 MIL set had audio as did the larger 1942 10" console with radio.

The 6" table model I have had audio added around 1942, for some unknown reason Philco decided to use their own version of the 6V6, a 6V5 for the audio output.

DaveA is the only one I know who has seen that set when it was in the old Atwater Kent Museum. I talked to him a few weeks ago to see if he could stop by the site and see if it is still there.

6" table model pre-war Philco?? WOW!!! I have never heard of that... could you
post more info? CRT number? Was it electrostatic or magnetic deflection?

I emailed the museum about 10 days ago to check on this and they have not answered. I saw it almost 15 years ago at the old AK version of the museum. It is now in new hands and no idea of what has happened in the attic.

Odd timing. I emailed a week ago. I'll try to see if I can get any answers via telephone.

You'd almost have to swear that Philco was slightly ahead of the game!
Magnetic focus and deflection, a slightly advanced CRT design, that could easily be converted to a newer 10BP4 type.
I realize that the RCA and others had magnetic deflection as well, but the old CRT's were harder to sub. :scratch2:

The 9" GE HM225 and 12" GE HM226 from 1939 used short Philips crts that were magnetically deflected and focused. The 9" MW-22-2 and the 12" MW-31-3 crt's are nearly identical in size and deflection angle to post war tubes.

IIRC they also were experimenting with high definition too; something like 800-900 horizontal lines...Unless I'm confusing them for another maker (I know some maker in the US wanted more than 525 before the war).

WHAT A FIND!!!

Where I live we get excited when we find a 1957 Philco... what you found is kind of a "Holy Grail" of TV collecting... congratulations!!!:thmbsp:

Wasn't France using 819 lines at the time? Britain was using 405 lines until 1967??? :scratch2:

The French 819 standard didn't start until after the war in 1949. The English 405 system ran through 1984. They started 625 PAL color broadcasts in 1967.

France used 819 lines at that time. A pity that their TV programming was really crappy in those days, it was a waste of their technology. They had only state television, and the programs on the air were very boring. That is one of the reasons why France had only 1 million TV sets in 1960.

I took the front cover off of the tuner today to see what I could see. It's not much to go on, but does any one know who may have made this tuner? Is it a Philco?

Under the replacement tuner bezel you can see 5 residue spots on the wood cover arranged in a circle. Could these be the remains of 5 channel labels from the original tuner?

One other thing I noticed while looking up at the set from below was that in typical prototype fashion this set isn't quite "finished" 100% as you can see in the shots below. It almost makes me wonder if they re-used a radio cabinet and re-fashioned the center for TV use.
