I am still re-assembling the "engine."
Had to take the whole thing apart to do the painting. I sure hope it works after I get all the boards back in. I found it easier to make an RF board and a separate audio board. My audio board is kind of a standard building block that I use with regens and ZN414 radios... just an LM741 driving an LM386. The BFO is a Ten-Tec "kit" board.
Hope to get some pix on the weekend, but have to go to the Silicon Valley ham swap at 5 AM tomorrow. 210 miles round trip but always a lot of fun.
PS: This was the "Mark I" version. The new set has a different RF board.
