Welcome!
I sorry to say that the Allwave Deluxe amp cannot (for many reasons) power an AW23 set. It's not just a power supply, it is also an amplifier and the two different parts are not compatible. The AW23 power supply is relatively…"

You can run them without tweeters, but be sure to move the "dummy" speaker plug to the opposite side of the speaker base. The plug adds a resistive load when the tweeters are not used. Leaving it on the "tweeter" side will…"

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 also interested to see what the wiring looked like - we have many schematics for the AW15 - what would this chassis look like?The serial number is A-263. I don't have any confirmed dates in prefix A, but 263 is early, since all the AW15 sets begin at 250 in each prefix. The set has a 55 detector,…See More

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.

Super XII Troubleshooting & Alignment
Posted on July 10, 2017 at 8:04am 1 Comment 0 Likes
I've spent several days working on a particularly difficult chassis and learned something I thought I'd share. First, here is what I had to start with: A nice single chassis Super XII. The IF aligned beautifully, and the 3 SW bands also aligned "by the book". The set sounded great on any SW band, AM was basically dead. There are only 3 things that are AM only, so I verified each coil. While checking continuity on the oscillator coil, I happened to notice that the 1K resistor seemed to move a…

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.

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"?
