I would like to find a manufacturer that can make high quality printed circuit boards, I was getting the from a company in the North-East but they haven't been able to provide them for me...........I have a copy to go by.......THANKS

Will, there's a fellow on another audio forum who designed a PCB for me from a schematic.  He does it for fun and a little bit of money.  It was not expensive, he sent me the Gerbers and I now order the boards from China and they arrive in about a week.  Would you like me to reach out to him and see if he'll do something for you?

Come to think of it, I know a couple of other fellows, veteran DIYers, who I'm sure are quite aware of your work, who also might be willing to help out.  Feel free to send me a PM.

"How much does it cost to have a Gerber File made?"

It can cost a lot if you go to a professional firm. Plus non-audio people don’t always understand what you need.  Little things like how big the filament eyelets need to be. stuff like that.  And you need to send them technical drawings, etc.

No problem.  I reached out to the guy, and he'd be happy to help.  It's just a side thing for him, I don't know what he does for a living. ;-)  He put an entire Williamson circuit on a heavy-duty PCB for me, they're terrific boards, better than I had hoped for.  I'm in agreement with Will about the advantages of a good circuit board.

I’d be more than happy to help, Will. If it’s the original Dynaco circuit, with the original eyelet inputs, I can email him a Dynaco manual and a picture of the original board layout and he can pretty much take it from there. The only data I’d need from you is is what tube you use in place of the 7199 and any changes you might have made. I’d also need the outer measurements of the board and the spacing of the mounting holes, but I can get those from any ST-70 replacement board. Florick is very experienced with tube circuits and will know what to do to make a nice, sturdy board. You can approve the design and I can order the boards from China for you. They cost, like $3 each. I could order a few and you can try them out. I’m right next door in Southern Oregon. No need to raise your blood pressure! ;-) If they don’t work out no harm done.

Believe me, the Williamson boards he designed for me are wonderful. They measure beautifully and are dead quiet, no ground loops, no issues at all. I love them. I was in the same spot as you, thinking how in the world could I get this accomplished, and in fact it was incredibly easy.

I’m semi-retired myself but my wife still works full-time and this sort of thing keeps me out of her hair.

I can see your dilemma.  Let me know if I can be of assistance, even just to put you in touch with this fellow.  He works pretty fast and it would cost a fraction of what you cited above, and far less than buying boards from these other sources in the long run.  At any rate, keep us posted.  A lot of us admire the great work you've over the years to keep the tube culture alive and thriving.

Well, I believe he's in the Netherlands, so sending the board would be a bit of a pain.  And I'm not sure he could do an exact replica.  But I think if you sent him pictures of the current board so he can see the layout and maybe even the traces, he could do his best to duplicate it.  I will send you a private message with his email.  

Thanks, moonwatcher.  I had a nice chat with Will and he sent me pix of his old board, which is very clearly labelled.  It's pretty much a duplicate of the original board with some spacing changes for the components he uses.  I'm going to send everything to this fellow in the Netherlands and see if he can create a board with an identical layout.  He's posted a bunch of free PCBs for various tube projects over at Diyaudio.  He goes by "v4lve lover" and he has some great stuff there for DIYers.  He made an excellent custom board for me, and I also use two of his other designs for various power supply elements, etc.  We'll see what he can do!
