JoaMat has sent me the board layout, and I'm working on it.

He did not need silkscreens, everyone else is definitely going to need them.

Could do it as 1 board instead of 4.

 

As one board it would be 11.77 x 7.8 inches.  So a bunch smaller than the 16 x 12 of the original

And using 10m90s definitely removes a bunch of parts. And so does the lt1021, although that one

part is probably double the cost of the led's and fet it replaced. Way more stable though.

Cheers to the sliver of hope that mere mortals may be able to own a T2, at least a higher chance than currently  ;D

Oh crap! I'm feeling the need to build this.

haven't looked closely yet, but you still have some transistors labeled with 2SC3675.

were you thinking of doing this as one or four boards?

four boards might give a little more flexibility in casing, you can stack the output stage over the front end

 

Might be cheaper to fab four smaller boards as well

JoeMat, Very nice! use LT1021 to the active battery is good idea.

 

Keven, can you add extra pattern for the solid state input (LSK389 and 2SK170 x2) option?
