I came across this just by chance on the Net. Philco made so many pre-war prototype TV sets. This one is especially nice. It looks like they used a modified model 680X console for it.
It would be great to find this in a basement of an old house!

That is pretty cool. Philco never actually made TV sets for sale until after the war, didn't they?

Speaking of flat, I remember this picture was making the rounds a few years ago. Can anyone remember the details?

Yes, the 1948 line, with the 48-1000 tabletop being the flagship set. I heard rumors that they actually did sell a pre-war direct view console, but I personally don't think that's true. Although the set was actually produced, I believe it was just for demonstration/marketing use. Philco was ready with television, but waited for the right time to begin selling them, like most companies.

The GE fan in the background appears to be the same model my grandpa used as a shop fan (I later saved it from Oblivion and use it for the same purpose he did).

Speaking of flat, and not for sale.....
We sold (Motorola Quasar) Panasonic for 50 years, along with Philco and Zenith and RCA. I used to enjoy seeing all their new ads come out.

150" Plasma! Wonder how many watts that drew at full brightness. My 55" radiates noticeable amounts of heat from the screen after it's been on a while, and it's one of the later (last), more efficient models, you have to be standing right in front of it to feel it though.

In case anyone wants to see how the entire set looks. Look at all those tubes! This is from the great ETF site:

Part of an RCA Design project called SETS OF THE SEVENTIES, done around 1961.

I remember seeing a Flat Screen Plasma display at an NAB in Las Vegas. I believe about 1985

it was sitting in front of a curtain and had a cable passing back under the curtain about a thick as your leg.

The heat coming off that Plasma was intense.

The last operating Plasma TV at my place of work is now in the recycle pile.

I remember that Panasonic Plasma from a CEDIA show. Must have been early 2000's. The picture was terrible, but it sure was huge! I sold the 85" version back when 85" TVs cost $30K+.

We bought our first big screen TV in 1982. It was an RCA 50" curved screen, with a fold out door, containing a mirror. It had three guns aimed at the mirror, red, green, and blue, and did give a very credible picture, for the time. I think I paid somewhere around $2600 for it.

Getting back to the original picture, the guy on the top left seems like he is marveling at the wonders of a fan spinning by electricity. This must be a really early photo. And what the heck is that piano for? Musical accompaniment in case of a problem with the audio on the tv?

This was one of a series of publicity photos depicting "... a special demonstration... on August 11, 1936... given by the Philco Radio and Television Corporation of Philadelphia, Pa." as described in an article on page 18 in the August 1936 issue of "Communications and Broadcast Engineering Magazine."

Continuing -- " The equipment used in this demonstration represented the results of over five years of research work by this organization and preceded the beginning of experimental work to obtain a higher definition picture (between 440 and 450 lines) to conform with the Television Standards as outlined by RMA [Radio Manufacturers Assn.]."

"The apparatus used consisted of the transmitter, W3XE, operated on a power of approximately 1 kW, located in the Philco Laboratories at Ontario and C Streets in Philadelphia. The signals of W3XE were picked upon at the receiving point some seven miles distant. [later moved to the Wyndmoor section of Philadelphia and in 1958 to Roxborough]

"Broadcasts began from W3XE on December 23, 1935 and regular nightly programs have been put on the air since June 18, 1936. Receivers have been distributed in Philadelphia and field tests have been carried on for quite some time."

The apparatus conforms to the standards set forth by the RMA with the exception of the number of lines and the synchronizing signal. This Philco system is of [the] 345 line type and a narrow vertical synchronizing signal is used. The carrier frequency of the picture transmitter is 51 mc while the carrier frequency for sound is 54.25 mc. According to Philco engineers, W3XE is using a new type modulation. The pictures are approximately 10 by 12 inches, and are black and white rather than the usual greenish or yellow type.

For the record, W3XE became WPTZ when commercial operation was initiated in 1941 but Philco sold WPTZ to Westinghouse in the early 1950s, the station occupying channel 3 until the all-digital switch over a few years ago.

It looks to me that this was a demonstration in some kind of meeting hall, where a piano would have been a pretty common piece of furniture. Useful for general entertainment purposes, prior to television's general takeover of our attention.
The electric fan had been around for about 50 years when the photo was taken, so I'm pretty sure the gentleman on the left was just caught at an awkward moment.
