Hi, I'll throw my two bits in!
Diodes from Efratom FRS, FRK, and M100 are made for 60Mhz drive and probably would be a good fit. I'll take a look and see if I have any junkers. All diodes used in Rubidiums are inside the cell oven so operate at a high temp anyway. I agree with Ed, swapping A3 modules requires retuning. One tidbit, make sure the two trim caps are actually rotating! The top rotor can get stuck and if you force it the screw connection will break. Then you have a fixed capacitor, not a variable anymore. If you check ahead of time you can break the rotor free by levering a tool against it laterally.
