I think for such a big group buy some more beta testing is required, particularly if a component that does not function as expected.

I think it would be better to get a small group of say 10 people that will build quickly to test. even thoguh people would be waiting, its much safer this way

It is a great OPINION, however PCB QUICK TO SEND TO THE MEMBERS ARE expensive! YOUR COMMENTS ARE NOT WHAT?

I WILL NOT DO BEFORE YOU TEST FOR 10 PCB, PCB ORDER WHEN I AM OK!

sorry i'm in a rush and cannot find payment details, I did not follow this thread lately, but I would still like to take my position. I too wonder if it is best to send out for test by people other than yourself for fresh eyes and different perspective. please do not take as an insult, just with such a large GB and with some inconsistencies, this is usually a good time to regroup. the design is obviously very good and has good heritage, but if there was issues with parts choice and placement on such a large GB, I would not want to be you.

just my 2c and again, please do not take this the wrong way.

I think the filament supplies could easily be tuned for 3v3 or 1v2 dac supplies yes?please let me know where to pay, but I must transfer some money to my visa debit so will not make payment for ~1-2 days. is that OK? I still have place?

With the two reg boards laid end to end as on your single PCB what is the distance from one end of the first board IRF9610 to the second board IRF9610? This determines how long the heatsink needs to be if we're trying to use a single sink for two boards.

The heatsick follow mA you need, I can set to chassis
You can se the Salas last i use for my Pre, one chanel need 80mA, i set I total 100mA!

I hope no one minds me posting this but finding big heatsinks in the USA has proven a challenge for me, especially ones that integrate with a tube chassis. With these PCB's you have to keep them and the heatsinks near the tubes not a separate enclosure. Anyway after getting outrageous quotes from several companies I found HeatsinkUSA, llc. They will cut any size you need and have fairly reasonable pricing. Integrating the heatsink seems to be the most challeging part of this project.
