I wonder if those will have the same info as what they submitted to Riders? At any rate the covers look really cool. :thmbsp:

Nice scoop and reasonable price for all of them. Still looking for a copy of the doghouse original manual. Close but no cigar!!

I saw those listed earlier and passed on them because they were not the full DuMont service folders, they were only the schematic sections.

And in at least one case (the 105 & 108) it was the schematic for only the main chassis (didn't include the power supply chassis).

I'm looking for the complete DuMont service folders for the Royal Sovereigns, the RA-119A and the RA-119B. If anyone sees those, I'd appreciate a heads-up.

Well, I guess I got gypped.

If anybody has the original RA-119A Factory Service Manuals, I'm interested in a copy.:smoke:

Well, what you bought may have some useful information in them. Typically the schematic fold-outs only have the schematic, a parts list, and some brief help like resistance and voltage charts (similar to Sams), but no service or alignment data.

I have the RA-119A Schematic of the same form as the eBay listing had for other sets. But the schematic is only for the power supply and other small sections of the main circuit. The schematic for the main chassis isn't even in there, it appears you are supposed to refer to the schematic for the RA-109A.

If anyone does find factory manuals for any of these sets and scans them, please send a copy to us so we can post them for all to use.

The only one we have is the RA-102

I think you should send that off to someone who would scan the whole thing for the ETF site. Lots of people will appreciate it.

I think you are right. Scanning this book would help alot of folks factory if can be tough to find. I should be getting a new computor and printer in the next month or so maybe I can learn to scan and do one model at a time. meanwhile theres always kinkos or my camera if anyone needed something before that. I dont know how I would copy the large schematics in one shot. that might require a large professional printer.This would be a large task for me since I am technology challenged. I just figured out how to post photos today. I bought a camera six months ago and just took it out of the box today. It's alot more difficult to play with you guys without a camera. I am so technology challenged that I have never owned a cell phone land line only.

Info for RA-109A is about 40 pages not including the 3 items in this photo. PM me and lets see what I can do to help.

I have the Dumont Doghouse RA-103 Ryders and Sams but would like to also get a copy of the Dumont RA-103 Factory Service Manual.

Does anyone have that?

TV'S&MORE, if you would mail the manuals to the museum we can scan them and return them to you.

Thank you!!! The original Dumont factory service manuals from the late 40s, early 50s, are very difficult to find, they will make great additions to the ETF site!!!

Yes, thanks. I'm already enjoying the RA-102 manual. So much better than the version in Riders.

Thanks to TV'S&MORE, the manuals are on their way to us. I'll start scanning them next week. Watch for them on our site.

You are all very welcome. Glad I can help. Thanks to the help of ETF a few more Dumont questions may be answered once this binder gets scanned. It seems like certain factory service information is quite scarce wonder where it went? When working on these early sets I try to use a multiple variety of service info whenever possible to compare info. Sometimes I only have Sams. Errors in Sams have let me down a few times caused me grief and has made me work harder than I had too. The more service information available to us the less confused we will all be.
