I am in the process of restoring a Phantom Deluxe remote control chassis. It uses the later, long amp. For testing, I pulled the 15 inch speaker out of my other Phantom Deluxe in the Stratford, and…Continue

I've had my AW15 in the Lido cabinet for over 30 years. Recently, it quit playing. This is significant because it was still sealed with rivets. To repair it, I was going to open a time capsule. I was…Continue

Unusual amp chassis

Folks - I have had this for years. I've asked before. We have a new, pretty active group here. What do you all think this might be. Speculate: what would the tube lineup be and why? I've long…Continue

The FM Phantom that wasn't

Posted on March 14, 2021 at 10:40pm 3 Comments

So this interesting chassis landed here this weekend, thanks to fellow member Dave Poland. He brought me a Phantom Deluxe, but I quickly realized, it was originally supposed to be an FM Phantom. In the first two pictures, note the plugged tube holes and the plugs and extra holes on the side of the chassis.…

AW23 Alignment issue

Posted on October 6, 2020 at 5:06pm 8 Comments

Looking for ideas - I haven't dug into this too far yet.

I recapped an AW23 (late) and I'm now working on the alignment. Voltage checks were in spec. IF alignment went right by the service data and trimmed out nicely. By the time I got back to the 1st IF, I had significantly reduced the generator output to keep the meter from going over - gain was excellent. On to AM band - 1400 trimmer is super close, slight tweak and then dial down to 600. At about 750, the two neon VR tubes…

Auction find

Posted on July 26, 2020 at 2:18pm 3 Comments

Picked up this one at an auction in Indiana. Disgustingly dirty, but salvageable. Had the 15 in speaker, tweeters, and a Tauscher sound board! Cabinet is good to start...the whole set will require a lot of work but will be saved.

All - The moderators removed an account that was a bit "phishy" today. We try hard to keep these folks off the forum, but every once in awhile, one gets in. Please ignore/delete any questionable messages and let's keep on talking Scotts!

that image is great! I will add it to the archive. Thank you!

Kent;

I hope this attachment works. I finished the composite figures 26 and 30 for the Late version 800B. I found this helpful in tracing out the electric tuning arrangement of the 800B receivers.

JoeIf this turns out to not be satisfactory resolution and detail, let me know and I will try sending the *.pdf file which is 5.3MB.

Kent;

I took a closer look at the Late 800B parts radio tuner chassis that I have. It is SN 6182 and I found its final test stamp inside the preset tuning assembly backplate and the date is Jan 15, 1947. So that one can be added to your database.

I took the time to take a good photo of the Late version 800B AM SW RF compartment underneath. This unit has never had any parts replaced in that area, so this part of it is unmolested. I had just noticed that the Early version SN 1035 that I have had already been worked on and there were some changes to bypass capacitor placement that I do not agree with. My intent is to put it back as close to original lead dress and parts placement as possible. Sometimes changes in part placement and lead dress can cause significant problems to develop and result in inability to properly align RF circuits.

Thanks you! I have added your cleaned up diagrams to the Scott Info Archive 800B folder. Your work is greatly appreciated!

Kent;

Yes I am willing to contribute these for fellow members and others use. I enjoy doing this type of work. I was originally in product documentation at Collins Radio which included doing schematics.

Joe -

That's great...when you get them done, I will post them in the archive if you are willing. All such work helps everyone here. That is what this forum is all about!

I will be working on the late 800B schematics as time permits.

Kent;

I have been cleaning up the schematic for the early (Feb. 1946) schematics for the 800B. Here are those two pages. I am working on another page that combines the radio tuner circuit and the electric tuning circuit on one page. The paper size is printable on 11 X 17 inch paper for the two files included here.

Hi Kent,

Working on pics and serial #'s, but what is meant by the term "Serbs"?

Thanks, Darrell
