Outside of a rewind or custom wound transformer theres not much available I use a 124e in my sparton 1466 which the push pull driver to push pull output was all so 4-1 with a 124e which was 3-1 I have had this radio since the mid 1964 and the original failed about 2 years ago so I know what it sounded like before it failed could not tell any difference this radio has variable if bandwidth 20 watts output and 12" woofer two 5" tweeters. I think it should be fine to use a 124b in yours I put it in the old housing so it still looks original,
