Looking for advice and ideas. I'm restoring an early AW23 for a friend. I replaced all the wax caps and have replaced the resistors in the C divider (out of spec, now have good divider voltages). IF…Continue

The title says it all...does anyone recognize this as a McMurdo Silver cabinet? I'm guessing it is not, obviously the mounting is all wrong. Opinions?…

OK folks...question: Here is the schematic of the outboard volume expander for an AW23. I was working on one earlier today and noticed a mod that I had not seen before. If this mod isn't factory, it was done a <long> time ago - near its original production. The mod is simple - a 20ufd/25VDC cap is wired from the 6A7 cathodes to ground (+ side on the cathode). It is soldered right on the wiper of the balance potentiometer. Any thoughts on what this might do? Should I remove it/leave it…

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.
Joe
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
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!
