"This version P.S. has a 6000 ohm bleeder on the 6L6 plate supply not found on earlier or later models. They must have gotten the voltage wrong or needed more current through the FC?"

I have a version of the MPV - MPVI power supply that has 5 tube sockets on it rather than the 6 normally seen on the MPV or the 4 used on the MPVI. Has anyone seen one of these? I have not identified…Continue

"That looks great!! Excellent restoration!

"Ta-da. Now for the PA."
"I am just starting on a 1939 Philharmonic Deluxe remote control set and the vast majority of the tubes in it were Sylvania "green leaf" stamped. The pair of 6L7s in the expander were both Arcturus however, as were a couple other obvious…"
"Ah yes, the RCA flat plate 2A3's in the AW-23. Aware of those.
The three AW-23s I have had all had a variety of tube brands."
"Norman, David,
I have seen what you have David. And in this set a majority of the ST green stamped tubes are Sylvania. So I am going that way. Yes, I was probably thinking of MS sets when I mentioned Raytheon.
So for the MSM V and VI I think…"
"RCA through the run of AW-23s. The AW-15 and at least early AW-23s originally employed the RCA flat plate 2A3 tubes. I don't recall ever seeing a hot stamp base Sylvania 2A3 in a Scott. Possibly Arcturus for the AW-12s but…"
"Appears shift to Sylvania midway through AW-15 era (late 1934 or early 1935) after Scott ceased use of Arcturus Wunderlich tube in the AW-15. Finding numerous early "hot branded" Sylvania tubes thereafter. Have seen many original green…"
"is there any consensus on which brand of tubes was generally OEM in Scotts produced up until 1940? I believe that they might have been Raytheon or Sylvania."
"Thanks Norman.
I have only seen these in this Phantom Deluxe "revised" (but no FM). I looked at an 800 chassis - not there. There will probably be a few others missing, but it is going to take some research before I know which ones.
This…"
"Russ, I have plenty of Scott OEM cardboard capacitor tubes. I'm sure I have a 279."
"Here is a little more on the original paper cap part numbers as I rebuild the ones I have.
Theses are marked with a cap value, voltage and usually , a 3 digit number. And nothing else. They could have been made by Sprague. The ones that i was…"
"Here is the rebuilt candohm going back into the Phantom Deluxe."
"Thanks.
Well, there are 2 .05 @ 400V caps in the power supply that I could use for a rebuild - it still has the 600V units. But, I am sure there will be more. I was particularly trying to ID the original versions of the electrolytic filters. I am…"
"Russ -
First off - for odd things like that coil, you didn't need to rewind it - I have over a dozen Phantom chassis available for parts, I can easily pull an original off one of these sets. This is true for any odd electrical part in the set.…"
"Yep:

In this unit they are mostly NOT Sprague.
I was looking to collect any available information prior to starting.
Thanks

Thanks Joe,
At the moment I don't have a project so I am doing maintenance.
I only have 2 Scotts, both are working along with several hundred other radios on display at my shop.
