Super XII Troubleshooting & Alignment

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…

Super XII Restoration

A Fast Tour

 

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:…

Shield Grid 9 SW coils

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!

AW 23 help needed

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…

Update to Scott Info Archive

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…

The AW27

All...here is yet another one:

http://losangeles.craigslist.org/sgv/ele/4711884421.html



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,…
