Problem- Synrad 48-2 Problem

[Gnu]

From what I understand after reading some posts here and there it's the RF boards that are broken.
I bought this Synrad from a guy in Germany who said it was like new and gave me 6 months warranty. Now I can't reach him so that's probably BS..

I've contacted Synrad describing the problem yesterday and are still waiting for some feedback.

I think both my RF boards are dead. I have an OEM J48-2.
First I lost half the power and then all. The green and red LED are working/responding as normal. I've checked the PSU (30.1V), tickle pulse and PWM and it looks good. I can even hear the noise when turning on the PWM. But no lasing.

On the Control board I have it says 01 rev. A

The two RF boards are a bit different. One is with the MRF151 and the other one have a MRF150 transistor. They are from 1997 and 1998.



The other boards capacitor have some minor discoloration and I'm guessing it's gone too..

Would really appreciate any input from you.
