Now I got in contact with Synrad. I'll keep you updated.

Well the situation is that there is no lasing at all so I guess both boards are dead. Or There is something stopping the second one when the first one is dead. Hopefully I don't burn my Fluke.

Thank you! Sorry for posting here in your thread without asking. Your name was the first to pop up in my head when the laser broke.
I'm on a mission to gather all the knowledge about repairing the synrads yourself

Someone said that you could tune this boards with an oscilloscope. I'm just guessing but I think you want the boards to be in sync?

OK I have two different RF boards. One has the MRF150 transistor, the other one MRF151.. I wonder if they have different MICA caps then. The blown one is quite unreadable..

Thanks for the advices.

I'll start with the caps. I've got two of them, one one each RF board.

Yeah I sure hope so. Thanks for the schematic. What voltage do you have? I have 30VDC.

Very very nice control box you've got there! Mine is not as nice but I have much bigger problems right now  

My Synrad made the worst kind of smoke. Looks like I could repair it but it would be nice to know why this happened in the first place.

Edit: A service manual would be good and schematics over the RF board. Synrad have not answered yet.
