The Fine Things are Always Hand Made
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…Continue
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!

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…Continue
The first step I always take is to remove all the tubes, shields, covers and anything else that can be removed from the chassis. This leaves us with something that looks like this:
And underneath we have:…Continue
Scott made plug-in SW coils for the Shield Grid 9. I'm researching them a bit and I could use more data points. If ANY of you have some of the SG9 SW coils, please contact me. I've got a few questions for you. Thanks!
Ok gang...so I have an AW 23 that I fully restored about 4-5 years ago. Played great. For lots of reasons, it hasn't been run much since then. I ran it up on the Variac this weekend, and here's what happened: AM and first SW band are dead, and the osc VR tubes don't light. On SW2 and SW3, osc VR lights up and the set plays great. Good audio on the phono input too.
So I take the tuner apart and check the osc circuit. The grid resistor is significantly off value, so I replace it. Clean…Continue
Fellow member Dave Poland asked me a question about the service manual for the Sixteen. That query made me realize that I did not have the PDF file in the "Scott Info Archive". I have just added two Sixteen service manuals to that folder in the Archive. Both manuals appear to be missing pages 7-8....however. the full size schematic is what spans pages 7-8, so those pages aren't missing, you just need to look at the diagram for those pages.
Please let me know if there is other…Continue
All...here is yet another one:
This makes the 18th AW27 set. In spite of this number (more of these exist than the pre-war FM tuner), there is no advertising, documentation or really anything on the "Baby-Q".
If you have any letters, documentation, an ad...if you have anything that might tell us more about the AW27,…
