Philco TA505 TV

[Gregb]

Check out my Christmas present from the wife! Anyone have any information on this thing? Looks to be some kind of teaching aid and uses the same tuner and IF strip as a Predicta.

That’s interesting does it work?

Not ready to power up yet, it is missing one tube and the power supply needs to be gone through first and there are a bunch of electrolytics scattered though out that should be looked at.

Yeah the power supply caps should be first. Do you have some kind of schematic to figure out what tubes it takes and of the whole circuit. Is this black & white or color judging by the size of the flyback it looks like a color flyback.

[Gregb]

I have no schematic or any documentation of any kind, I was hoping someone here would have something. It is black and white for sure.

[timmy]

Could be a teaching aid right out of Philco for there own techs. Very interesting project would like to see that working. No schematic hmm that’s a bummer but take your time and you will get there.

Man that is extremely cool! What a find! I'm looking forward to see what we find out. Definitely reach out to the ETF and see if they have any information on it (I'll bet it's something they'd like to have).

Thats pretty pissah. Its a trainer, I have seen others I think RCA.
For a manual date code some of the big parts, make a tube list.
Then post it here & I bet it almost matches a Philco TV.
Someone will recognize it then you can get a Sams.
Maybe find the real paperwork in time.........

Who ever picked this for you really hit the nail on the head ! It
would be hard to beat IMHO.

It looks very clever for instruction. The major sections of a set are on the front in blocks (B+, IF, audio, sweep, et al.) just jumpered between. The local components are on the back where the instructor could easily insert a bad component/board to track down. Start on the front tubes to isolate and then move behind to the components. The schematic for this had to be an adventure in parts locations. A one-of-a-kind score.

Very cool. Philco used that same IF strip in many sets for several years. The rest of the construction looks custom for this trainer.

Looks like Predicta/Seventeener IF strip. What a cool piece! What does it say on the Philco badge on the bottom?

[Gregb]

The little tag just shows the model number, TA505, and power info. Made in Canada

Todays project is make a tube list and see if I can get some info on some of the parts and post here as suggested by Zeno above. Maybe someone will recognize the layout.

[Gregb]

Here is a tube list, if you recognize please let me know. Thanks
I will have to pull some modules to get any part numbers and that will be next.

Tuner 6GK5, 6HG8
IF 6DE6, 6DE6, 6AM8
6BY8
2 X 6AW8
6CS7
Hoz Out Module 12AU7, 12BR7, 6DQ6
6DA4
6AB4
2 X 6AQ5 audio out module
1 emty 7 pin socket

[init4fun]

I wonder if the empty 7 pin on the audio module might be a 6AV6 (or 6AT6) ?

Also, I might as well join everyone else in saying GREAT SCORE !!!!!!

[Gregb]

It could be, at some point I will start tracing the circuit back and see if I can figure out what tube should be there.
This is a great score and I am hoping it will help me improve my TV repair skills.
