PSU Board

Jan,
I think a PSU board would be a good idea, as long as it's more than the standard "minimalistic" PSU boards we see around here alot.

Maybe something that would accomodate (and utilize!) the MUR3020, 3060, etc rectifiers. (There are some PSU boards that have the mounting holes for them, but don't utilize them correctly/completely!).
There could possibly be mounting holes for screw type mount filter caps as well as the normal snap-in. Either for mounting directly to the board or wire connections. Nice mounting points for power chokes. Enough room for a complete CLCRC or similar PSU, etc.

These were just brainstorming idea's so nothing that's been totally thought out. I am just hoping to stimulate some discussion on creating a really nice power amp PSU board.

Thanks,
Donovan

Now 38 LYNX PCB's 🙂

PSU board;
I normally run this amp with a traditional PSU consisting of toroid, diode bridge and 20-40,000uF per channel.

I think it would better to start a new thread only for the PSU board group buy, as it is a new project and because others who have no interest in the LYNX amp could join in......

Would someone here start and take care of this thread (my spare time is limited at this moment) ?
I will then make the layout (and have the PCB made) according to what have been decided 😉

Hi Jan

As the Lynx amp PCB count is up to 42 boards, how long will you keep this open before taking a commitment from everyone involved.

Anyone interested should indicate their interest here in this fine design.

Cheers

Gary..

Sure,

I just checked to confirm. Shipping a 500 gram (or less) package anywhere withing the continental US from my address will be $5.00. That includes the shipping envelope and all postage. The price as quoted is USPS Priority Mail using their 'flat rate envelope'. Delivery in 2 days.

Do we know the shipping weight of each PCB?

Best Regards,
Carl Huff
