Hi,
I recently get a revox b77 mkii. The heads look pretty clean, un-used almost. I was trying to set it up but don't understand why everytime I make a recording, it always turns out very noisy, filled with these seemingly random scratches. Here is a link to the sample of this problem, please have a listen and advise.

I have changed all the capacitors on the Record amp pcb, and also the input amp. Still the noise persist.... Here is a new sample of this scratchy behavior, please any B77 experts, chime in, your help is much needed... Another strange behavior of the unit is that most times when I turn it on and there is a tape loaded, it automatically starts playing.

I've had the same problem. It turned out to be the relays on the oscillator board. (relay contacts worn/dirty?).
A new oscillator board cured it.
