Finished...   Back plates before I mounted them...

I finally got the last plate machined.  I had to replace the spindle on my CNC and also made a mistake on the CAD so had to redo this plate, but it's looking great now.  

Been busy at work, but managed to pull a new version of the T2 amp board together. I've added separate modules for the active batteries, balance servo, pre-CCS feeding the output CCS and the opto

I found a source for a board set thanks, ordered the silicon (DAMN THAT HURT BAD), Penny and Giles pot (already numb from the silicon), and transformers. All the major parts.


KGST smoke test today, KGSSHV in a month, Megatron about 3 months out, T2 by end of year.

Great and ambitious lineup !

I'm also stocking things for this beast, but being a slow builder it's going to take several months...

I'm gathering mods ant tips in the thread for now.

I have a quote for 4 sets of PS and Amp boards, I need one, three (only) more participants and I'll do the run. 


  • Blue board
  • 92 mil board thickness (thick but not too thick)
  • 2 oz trace

I got them to come down a bit on the cost, it's now $314/set + tax and shipping. On this one I'll eat some of the cost and joiners can get them for $300 + shipping to them. I've got quotes from other sources and they're coming in more expensive, such as $280/board. 


Edit: This rev of the board (known to work)


Here's the AMP board



PM me if interested. 


I also have an unusual/rare board I can't use, it's for standard off the shelf 400mm heat sink, is .125 thick with gold mask, if anybody is interested ($240 shipped)
