😱😱😱
Valery,just a note.
I see this pcb ,i think that traces are thin and pads aren't ideal for hand drilling

Just leaving the place it occupied during the last few years - it will take some time to find the new place, likely closer to my home, and re-assemble everything
Hi Valery,
I will build it but I use iron transfer so I need your files mirrored from what you have posted. It would be nice if you could post one with see through showing the silk over the traces for easy troubleshooting.
And, Like thimios pointed out, maybe enlarge some of the pads a bit.
Thanks, Terry

Parallel - updated bigger holes / fatter traces
Hi Terry,
Great! I hope, now it's easier to etch / drill.
I have printed the mirrored PDFs now.
Cheers,
Valery

Yes... unbeatable 😎
I have already mentioned somewhere - in general, I think slower than Terry builds

A few traces close to the bias spreader are looking a little bit close to each other, but I believe it will be possible to separate them, right?
It really takes less than an hour. I had to wait for the wife to go to the store so I could steal her counter space. 😉
I have the holes drilled now. One nit pick if I may. If laying for etching it is nice to under-holes a little. It acts like a center punch and leaves more copper after drilling. I like to use a 6mm bit for the small resistors and caps. 8mm works fine too. I realize that you have to error to the larger size if they are through hole. I'm only speaking of etched single sided boards.
Blessings, Terry

When I used to hand etch, I would make all hole sizes .025". This would leave a tiny center punch size hole in the copper for drilling. This worked especially well for larger ICs. Much more accurate drilling.
Right, I see. We need relatively big pads for better soldering and small holes for better drill centering.
Thanks Valery,yes inp.caps are missing if you want MKP type.feedback resistors also missing(CFA amplifier) and some 100pf caps.I will built all with what i have and then i report what is missing.😉
