sharp gf 9494

Which vintage compatible microphone worked on or was for the Sharp Gf-9494? I’m retro fitting all my blasters with all kinds of awesome add ons and accessories but most double prong microphones are to narrow and won’t fit in with the Sharp.

Last monday (8 days ago) has the gf 9494 arrived me. The condition was ok, but i needed this rubber for that tape deck, a battery cover and all the other typical repairs... Cleaning... Line in- phono / before And after my line in tuning, looks like original Very dirty even more dirt...
