"Thomas - Thanks. The Hammond site for classic P-P transformers show the same 15 watt units as AES and Radio Daze, but with more information and a chart of connection combinations. Does not show ratio information. Norman - Thanks. So I'll repeat…"

"Dave: I would want to see the tables before ordering the transformer.  Most of the impedance ratios will be duplicate ratios such as 2500:8 and 5000:16.  An impedance ratio of 6000:15 is electrically similar to 15600:39.  Unless…"

"Thanks Norman. So  a "ball park" output transformer with 15 ohm impedance may be close enough. Then, seems worthwhile to order the 15 watt Hammond P-P universal replacement from AES (or Radio Daze) that can provide 15 ohm impedance -…"

"The impedance ratio is the critical characteristic, not the rated primary and secondary impedance.  The impedance ratio is the turns ration squared.  Therefore, having a turns ratio of 20:1, the impedance ratio is 400:1 (full primary to…"

output transformer for the 12 inch Magnavox speaker for the Sixteen, Masterpiece & early Phantoms

The target output transformer is for the 6V6 push-pull amp to a 39 ohm impedance voice coil.A VTVM shows a resistance of about 30 ohms for this voice coil. The model Sixteen, 14 tube Masterpiece and the 1938-9 Phantoms using 6V6 tubes use the same 12 inch speaker with the same field coil configuration and 39 ohm voice coil.This Scott Magnavox speaker is model 302  and part number 645   171.The speaker basket rim says   Spec-1-1148      also says 1416.The problem is I need an output transformer,…See More

"Yes, that is the correct serial number. I was more impressed by the certification paper. It has the guaranteed stations logged by the factory during testing. It's the small paper at the bottom of the console catalog."

"Especially the guarantee document - appears to read Ser# Z-80 and date of Dec 1933? Is that correct?"

"A really nice looking correct example. With that speaker should be the AVC version with a blue glass  Arcturus Wunderlich tube as 2nd detector.  (3rd tube back on the left end of the receiver.). The Olympia is a mid priced Scott cabinet."

From the estate of a friend: Truly excellent chrome, late AW12 single dial, working chassis. Olympia cabinet has never been cut for a phonograph. It is marked inside: Peerless Furniture Company,…Continue

Appears to be a utilitarian variant of the 800. No chrome or evidence of a SN tag but lots of Scott "goodness" below. With the 25L6 outputs, no audio piece, and has a PM speaker. Guess is a military…Continue

Scott Allwave 1934 radio -- repairman needed

Posted by Curtis Walling on July 24, 2016 at 3:24am 12 Comments

My mother is elderly and owns the following radio, it is in great shape but nevertheless needs minor repair and restoration:

 I inherited my radio from my parents who purchased it when they attended the

1934 Worlds Fair in Chicago.

It was purchased, paid for. and then shipped to Arizona where my parents

lived.  It apparently is a Tassman model - this info was given me by my son Curtis

Walling who did some primary…

Philly Amp wiring

Posted by Joe Miller on July 20, 2016 at 9:57pm 0 Comments

I am working on a Philly amp and am finding a number of wiring mods that deviate from the schematic. Some are due to someone bypassing a bad audio transformer and for adding a second phone plug input with volume/mixing pots.

But I also found a 125 ohm Candohm type resistor that is factory mounted to the side of the amp chassis. It is connected in series to the cap connected to pin 6 of the set plug socket and then tied to ground. It doesn't show on the schematics that I…

My Philharmonic featured on SWLing Blog Post

Posted by Ken Carr on April 6, 2016 at 1:14pm 5 Comments

I subscribe to an excellent blog called the SWLing Post. It is run by Thomas Witherspoon, a man who has boundless energy.

Recently he featured a Crosley radio that was competing for the high end market back in the late '30's. At the end of the article he asked if any of his readers had a 'benchmark' radio. 

I responded with a few photos of my BOL Philharmonic and he created a post from my information.

Glad to be here and hopes my builds pictures are liked and will post some of my E.H.Scott sets

Posted by Paul W. Meyers on February 29, 2016 at 7:00pm 0 Comments

I am glad to see all the nice pieces on here. I am a collector and it never seems to end.When I was in High School made a communications radio and won a blue ribbon 1st place in K9EWU'S Don Houdes electronics class class and had a project when I was in College and had access to the metal shop. Was good friends to one of the teachers. wanted to make a high fi amplifier. Well made a 50 watt stereo unit and wished I kept it as it was. Made it into this big thing. A friend of mine spoiled with…
