You will want a speaker that has the small 4-pin plug. Type H was used in models 77 and 96. Type H-2, which is electrically identical, was used in models 111, 112 (early version w/2-45 outputs), and 90 consoles (early version with 2-45 outputs).

An H-2 from a 112 or early 90 would be ideal, as these have open spiders shaped like a 45 rpm adapter and produce the best sound. Type H and early H-2 as used in model 111 have the same solid spider as used in model 20 speakers, which somewhat muffles the sound and decreases fidelity.
