Schematic for the VM204

Would it be possible to get the schematic for the VM204? I’m thinking about removing the relays and adding some RF ones but need to check how they’re wired and determine the current ratings etc.


Hello Robbo,

Here can you find the circuit diagram of VM204.

Good evening,

I have damaged my VM-204 and in need of a schematic to determine the transistors and IC’a that may need to be replaced on the input logic. Could you share the schematic with me as well? The link on this thread is no longer good.
