Product Reviews
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.
