AMMRL: Proton amplifier on Varian Mercury Plus 300

Hi All,

We had a Varian Mercury Plus 300 system which is 15 years old. Recently we noticed the proton channel is extremely low in power (with 90 degree changed from 15 us to dramatically longer). The proton decoupling doesn't work either. The carbon channel looks okay though. We suspect the proton amplifier is dying.

1) Do you know where I can get a functional proton amplifier for Varian Mercury Plus 300 system?

2) Other than the proton amplifier, what else could the problem?

Thanks,

Jinfeng
