Hi,

Is there somebody you built a control board for Synrad tube or is there somebody who can tell me what this board must do or is there somebody who can help with a schematics of such a control board. I would like to build a CNC laser with a used synrad tube. The control board is doing the connection between PC and the RF driver of the tube. Through it the PWM is sent for modulating the output. I have no idea how to build this control board. Please, help me.

Thank you.

Zoltan
