- Our part number 124C (below) is the COIL ONLY (for those experimenters who want to use their own “iron”).
- If you are looking to replace Radiola III-A audio transformers, check out our universal radiola replacement unit.
Hookup Data
- For Parallel connected operation (33.8K Ohm Secondary):
- Connect the GRN/YEL wire to the GRN wire AND the BLK/YEL wire to the BLK wire.
- Connect the GRN/YEL wire to the GRN wire AND the BLK/YEL wire to the BLK wire.
- For Series connected operation (135K Ohm Secondary):
- Connect the BLK/YEL wire to the GRN (this becomes the center tap) – GRN/YEL and BLK wires are the output.

“Classic” 600 Ohm 119DA Series – (119DA) (DISCONTINUED)
In response to requests from the “Collins Collectors Association” we developed a high quality, matching audio transformer for older equipment with 600 ohm audio output, driving modern low impedance speakers.
Or it can also be used for driving “classic” high impedance speakers used with newer equipment. Simply turn the 119DA around – swaping primary for secondary (ie…4 or 8 ohm input – with 600 ohms out).
Features
- Large core area for excellent low frequency response
- Manufactured with high quality 29M6 laminations (for low distortion)
- Concentric wound for excellent coupling
- Isolation type transformer (ie…separate primary and secondary)
- Primary: 600 Ohms (using 6″ wire leads)
- Secondary: 8 Ohms with a 4 Ohm center tap (using solder lugs)
- Power: Rated at 12 watts
- Frequency response: 30 Hz. – 20 Khz. (+/- 1 db @ Full Power – 1 Khz. Reference)
- Weight: 1 pound, 4 oz.
- Mounting: 2 hole bracket mount – on 2 & 13/16″ mounting hole centers
- Cost: under $40.00 U.S. !
- IN STOCK – check out our Classic Distributors.
