"Norman -
It is unusual for the P/S chokes to short to ground. It probably got hot due to a shorted filter and melted the internal insulation. Fortunately, I have some spares around here. Unfortunately, I am leaving early tomorrow morning for the…"

Scott speakers
Started this discussion. Last reply by David C. Poland Apr 29. 14 Replies 0 Likes
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
AW23 osc issue

Need ideas folks: I've got an AW23, fully restored, used to work well. Tried it this week and it powered up ok, but the neon VRs lit, dimmed as the tubes came alive and the went out. Set doesn't…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

"Bret -
Glad to meet you and know you got several of the sets from the Sargeant auction last weekend.
That is not a Scott cabinet. From the design and structure, it was a much earlier cabinet, probably originally held a crank phono with a horn…"
"I added a couple of the images to the cabinets folder - thanks!

"John - Actually, the later Phantom sets (and the Super 12 and Masterpiece) all used an octal connector for the speakers. These are nice because they are relatively easy to come by. The diagrams in the Info Archive will show these connectors.

"One advantage of the power handling capacity of the toroidal is suitablity for the standard 38 ohm speakers for the higher power 40 watt Philly and 30 watt Phantom Deluxe amps using 6L6's. (Also the 1941 Scott Laureate with two 6L6's in…"
"OK...so I just patched everything together and tried to operate the 12 inch speaker with the toroidal filament transformer. Guess what...it worked well! Sound isn't great but the speaker is unmounted and was face down. Tone controls worked…"
"I agree with Dave - I look closely at the set and if it appears to be original, I stay with what is there. Check the AW23 data in the Info Archive, there were several documented production changes described in the literature.

"Kent, just what Norman said. The impedance of the speaker is reflected to the output tubes after being multiplied by the transformers impedance ratio.

I found this years ago, cant remenber where but it was pre internet days.
Decide what primary impedance you want. It might be 5200 ohms for an EL84.

"Never occurred to me such a transformer could serve as an output transformer. And for a lot less money than current output transformers with sufficient wattage (Antique Electronic Supply ) if they had one for a 38 ohm VC.

"Turns ratio is equal to the transformer primary voltage divided by the secondary voltage (four combinations available). The impedance ratio is the turns ratio squared. The voice coil is 38-ohms. The original Scott output…"
"Scott - I got the transformer today and it also has a dual secondary - two 12v outputs. To get the 38 ohm match to the VC, did you use one of the secondary windings or both (and in parallel or series)? How did you wire it in the pedestal?
Kent"
"Jiri - Not inappropriate at all. I share your concern, too many of the high end sets are split up for $$. I hope we can find a good, safe home for this set, it should be kept together.

The FM Phantom that wasn't
Posted on March 14, 2021 at 10:40pm 3 Comments 0 Likes
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 0 Likes
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…

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!

Hi Kent
I'm Keen to get a copy or the collectors guide
However I would need it shipped to NZ
The eBay listing doesn't ship herec
Got any ideas as to. How I can get one
I've just signed up to pay pal if that helps

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.
Joe
If 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!

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.

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
