Good day all, I was looking in the builders guide, on the forum, in build pics... the only thing that I could find was:

I've just built a Triwatt (btw congratulations Stephen on an excellent quality kit) and have successfully added a passive effects loop. All it needed was an interrupt between the MV wiper and the 22k resistor into V3 pin 7. I was expecting potential impedance mismatch requiring a 1M to ground at the return, but did not need this. Also did not need a coupling cap. Very simple mod and the amp sounds great.
To accommodate the send & return jacks in the chassis I plugged the hole for one of the speaker jacks (the one nearest the OD footswitch) and drilled two new holes just above and just below that plugged hole. Works well, and places the send and return jacks in exactly the right place to have the shortest cable runs possible.


Thanks for sharing your success. We'll put that into the builders guide for future builders!


Is there a schem or pics anywhere ???

Edit: Now both are here

Thanks for the help

Just hooked the loop, From SEND to Master Volume middle pin and RETURN to terminal strip shared with R17 22K

but forgot to remove the existing wire from MV-pin2 to R17 on the terminal strip !!! Double feed CARNAGE!!! lol.

Now without the previous wire it's working like magic!!!

Thanks Stephen

I did drill 2 more holes just in case I wanted to upgrade for the OD footswitch... (once I'm done with my OD problems...)
