Default Revox A700

Hi All

I have Revox A700 tape recorder in good condition which has been given to 60+ years old technician for refurbishing. I am planning to change TBA931 with direct equivalent SN76131. It means I don't need to do any modification on any other component except TBA931. Also where do I get them SN76131? Does any later years Cassette decks from Technics, Akai, Pioneers used them, if yes then I may get them!

Hi,

I am getting SN76131N, can it work in place of TBA931-1?, hope it should. I am told that TBA931-1 /2 /3 are differently calibrated as they are placed on different purpose boards in Revox A-700.

Thnaks,
Sach
