Crosley bakelite tv

[Radiotronman]

I also forgot to mention I don't have any audio yet, just a him from the speaker. Here is a picture of the set..

I checked all of the resistors around the 6SL7 horizontal oscillator tube and didn't find any out of tolerance. I changed the 6SL7 with a new one and no change. I double checked my cap replacements to see if i made any mistakes and they're all good. More studying of the schematic....

Can't speak for others, but I do not recognize this set.

Crosley TVs were never big sellers, although their radios were very common.

If the schematic is available on line, how about a link to it, if not, how about a scan of the horizontal section so someone who might help you could determine what circuit this set has. Just a model number could help.

A test please: By adjusting the horizontal hold, can you make the set lock in somewhere and go out of sync on both sides of where it locks in? Or does it lock in at the extreme end of its range?

Reminds of a page that I ran across the other day. Scroll down and look at the TV pictured for 1954:

http://www.crosleyradio.com/about

And I quote: "The first portable TV set was pioneered under the Crosley brand name, and becomes the best selling set in the industry."

What a hoot. TVs of that size (and smaller) were sold years earlier by other companies. And I seriously doubt that TV was really the best selling set in the industry, in 1954 or any other year. Never laid eyes on one, myself.

In fairness, that website has little connection with the original Crosley company. It's the headquarters for selling new repro sets under that name.

That set came out in the late 40's like the the rest of the E'stat sets.
The Motorola was the best seller of all of them.

Ok I changed a 120pf mica on the 6sl7 sync clipper tube along with a pulled out of tolerance resistors. It will lose sync for a few seconds from time to time, but will snap back. I've also got to figure out where my audio is lost. It's by no means perfect, but we are getting somewhere...

Vid. detector diode's OK. Scratch that idea.

I looked up the set in Rider's #5, which I think is the set.
The schematic shows a 6SN7 tube as the horiz osc in a syncroguide circuit.
Make sure the .01 cap across one of the coils of the synchroguide transformer is proper.

Sorry guys, I meant 6sn7. The model of the tv is 10-401. Below is the picture of the horizontal section of the schematic. I cannot get the horizontal to lick at all.

It's really close, just can't get it locked yet.
