Also Adam, it would be absolutely fantastic if you could guide us to a manufacturer in China that produce good copies of now defunct transistors. There are many on ebay as you probably know. It would be a good exercise to test them without spending your money and waiting 3 months to arrive to find them defective in an area you are interested in.
I'm not tasking you with this mission, I'm just asking for a China manufacturer who is true to the original specifications.
Adam, snap to a grid of 0.1 mm if you do a pcb. I'm not sure there will be many takers due to the amount of same frequency crystals which are rarer than unobtanium any where else other than China. This is why there is not much development anywhere else in the world. China can produce crystals on any freq on demand. Western world add $25.

It’s been a while. I wish to present the recent design. The only semiconductors are 13 piece 2N4401 and a few diodes. The output is 1 watt SSB and it is a practical number for 40m FT8. Still long time to finalize the design.
