The board in my previous posting were EXPENSIVE !!!
I added black solder resist and ENIG plating.
That pushed the price for 10 boards up to about USD 12 !!!
However, I also elected to pay USD 25 to have the boards DHL shipped back to the UK - whilst this is a significant uplift for 10 boards, I was having batches of 50 at a time made, so the uplift was tiny.
Note that having 20 or 30 boards made at a time is not that much more than 10.
EDIT: Should have added that quality is pretty good and that the boards above were for a "statistical regulator" HV project, first mooted by Morgan Jones in the 4th ed. of his seminal work, "Valve Amplifiers". In the end, I distributed about 200 of those kits, including giving one to the man himself (MJ) at an Audio Talk gathering in Owston. Boards are shipped vacuum-packed to ensure they arrive nice & dry (important if you are putting them into a IR oven).
Not made a board myself for many years now. Anyone want to buy a really good, hardly used, bubble tank?
