Transformer - Hammond, Radiola III-A Replacement Audio
Developed in response to requests from RCA Radiola III-A collectors. The original transformers are usually found with open windings due to the fine wire and high turns used coupled with age. This is a universal replacement type - it will replace any of the three audio transformers used (1st audio driver, 2nd audio-phase splitter stage, or output transformer) by correctly connecting the 5 lugs. A pin out and connection diagram is included. The cases from the old transformer will fit this new unit. The terminal board is a duplicate of the original.
Key Features
- Primary: 4000 turns, #41 wire (lugs 4 & 2)
- Secondary: 12000 turns C.T., #41 wire (lugs 5 & 1lug 3 is C.T. connection)
- Termination: Solder lugs on a 1 ¾" x 1" terminal board with 4-5" connecting leads
- Size: 1-⅞" long x 1-~\frac{11}{16}~" wide x 1-⅜" deep
- Lamination Core Size: ⅝" x ½"

Excellent Thank you
highly reccommended purchase, fluent communication with the manufacture. In less than 3 days the ítem was delivered.
I've used these in Atwater Kent models like 40, and 45 with great results. I had to de-pot the old ones and grind down the corners of the new transformer to install them but it was worth it.
This is an almost perfect replacement for the original Radiola IIIA transformer (not the same color but excellent fit); I have also used it for the Westinghouse RADA-while not a "perfect" fit it will not require modification of any kind and works quite well-a purist would complain but now I have a working 93 year old radio.
Worked and fit perfectly in my Radiola IIIA and for a reasonable price.
