The schematic of the first part

Follow this link to upload the first part ( the split manual section )

Just a thought ...

Would there be any demand for a fully mounted and tested upgrade box ?
If so, I can always start to assemble.
Please let me know.

The mystery relay board ...

The relay board has been designed to be mounted near the Modulator boards.
It has 2 relays of 12V connected in series ( Re 8 and Re 9 ).
There is also a solder place for a resistor ( RR )in case you would like to use relays with a lower voltage.
Normally, when using the 12V relays, this Resistor can be replaced by a jumper wire.

The modification on the PCB

It seems that I've not posted a picture of the small modification on the PCB as stated in the manual part 1.
So here it is !
The red lines are the cuts on the copper tracks.
The yellow lines are tiny wires to be placed.
