I am building TC-15 with VRM. This is my first amp build ever.

I can't seem to find a doc that shows where/how to wire in the VRM. Does the pot replace a stock pot in the build?

If anyone can point me to a range of photos or graphic layout, I would very much appreciate it!

Heres one in an 18 watter (same chassis). Should have come with a switched pot so you can replace the power switch or wire the pot in the back like this one. (your choice) if you do a forum search for "VRM" you should come with a few examples in other amps

Barring having done something stupid--like confusing pot terminals--the VRM installation was much less difficult than I made it out to be initially. Stephen was a huge help, in steering me to the right docs and patiently answering poorly worded emails!

I replaced the Power Switch, and I could not solder the pot to the VRM board and make a good connection to the chassis for the MOSFET, in that location. So, I mounted the VRM board to the chassis, directly under the pot and ran short, twisted wires, from the pot to the VRM board.

Below is a crap photo, taken late last night, on my phone. I will post better photos of my project, when it's finished, and I can confirm that I am not posting photos of bad implementations ;-)
