Curious of methods and materials best used for chassis rust ? I suspect they'll be some pitting as there are areas beyond "surface" condition.Continue

I've been patiently waiting for the "right" cabinet, this one began life as an early FM GE phonograph, a optional cabinet of the same Radio now housing my 800b. Both with the full doors are difficult…Continue

"Hello David, thanks for helping out. Cell works where we can exchange email for better resolution as needed."
"Dave - I have Gerry's diagram for a version MP4 with 4 push-pull parallel 6B5's. 2nd AF is a pair of 6C5 drivers on the amp. Two field coil speakers: one each bass and treble.
Diagram date;11/20/35. As usual, no parts values, just…"
"I never got all of Gerry's MS materials. We did an exchange of data once back in 2006, I have everything from then, but that's a long time ago. And nothing in there on the MPIV you need.
Sadly, I haven't talked to him in quite some…"
"No, I have not Kent. I know Dave and others here may have some of Gerry's work, should be a treasure trove but I lost touch with him and not sure his work was printed ?"
"I looked through my MS folder (not very extensive), I only have schematics for the earlier version using the 42 outputs. Hopefully, someone here might have more. Did you post anything on the Antique Radio Forum?

"I have tried phosphoric acid (same ingredient as in naval jelly) and it dulled the chrome around the rust spots. I think if you keep it confined to just the rust spots you will do a lot better than I did. Otherwise the best I have…"
"Another method, if you have more significant rust, and you remove some/most of the components, is to use Naval Jelly. Apply, wait, then wash it off with a lot of water and let things dry thoroughly. Repeat if needed. Then polish as Dave…"
"So far, limited to using Turtle brand liquid chrome polish over the past 20 odd years. But then I have avoided heavily corroded items.
Vacuum first while using a modernly stiff artist brush. Use small squares of old towels, gentle pressure and…"

Dave - I attended the auction and looked the early AW-23 Scott 5 knob radio over. No statement made of the working condition. I passed it up.
Sold for $750 plus 10% gallery fee plus 7 1/5% State tax - so pushing $890.
A lot of corroded chrome with some bubbling and pealing on the receiver and amp. Sovtec output tubes. The cabinet had been refinished with a rather flat finish which pretty well hid the beauty and depth of the fancy fiddle grain tropical Laurel veneers. Oil finish? The Richmond Designs repo Aztec speaker cloth (a darker 70% scale repo of the original gold cloth) has a bit of a green cast that, to me, did not compliment the blond cabinet.
I was not interested. Looked like more work that I was interested for result unsatisfactory to me. (I have an excellent example in that cabinet already.) Hope the buyer restores it, rather than parting it out, Properly restored electrically, a great sounding radio.
