Crosley 9-409M1 Schematic - Videokarma.org TV - Video

Does anybody know if the Crosley 9-409M1 TV is in the Sams photofact 66 folder 6? I found it listed in an old PF Reporter on archive.org.
I'm looking to find it somewhere, if anybody can confirm that it really is the M1. I have the 94 folder 3 but alot is different. Like a 6AU6 in the IF instead of the 6AG5 that's in the M2 & M3.

The TV was worked over by a hack and its hard to follow. Thanks

Hi,
Are you sure about the model number? How many video I.F tubes does your set have. The 94-3 schematic shows a circuit variation in the bottom left corner with an extra video I.F tube.

It's a 419-M1 I didn't see it clearly. Sorry.

Do you have it?

You stated earlier in this thread that you have folder 94-3. The information you need should be in your copy, unless it was revised? I cross referenced your chassis number from a 1953 Sams index.

Yes but many (a lot) of the schematic values don't agree with what's in the chassis. 6AG5's changed out to 6BA6 & vice-versa, C10 is backwards in the diagram, etc. It's easy to get lost....

So if anybody has an original Crosley manual, maybe that will help.
However thanks for trying with the Sams.
