Hi Ben, You just made it on time and the board has been shipped today. Thanks.

Hi Peter. Green PS boards arrived.

Thanks, JC

Don't you think there is a mistake in the bom
Q3 and Q4.
My F5 is burning, j hope you have again some boards,
Philippe

The BOM in post #8: http://www.diyaudio.com/forums/showt...41#post1777841 indeed seems to contain an error: Q3 should be FQA12P20 and Q4 FQA19N20C
It wasn't my BOM and I found that link posted somwhere on a Forum. Didn't check it either, as I'm using IRF mosfets.

The boards are still available.

Hello Peter. I recieved my PCBs today. They look GREAT !!! Thanks!

I am having trouble finding data for the diodes you had mounted on the PS board though. Any info you could provide would be appreciated . They appear to be from Harris\Intersil Which sold their rectifier devision to fairchild I could not locate or cross reference the part #IH49415.

Thanks,

Brent

Peter -

Received all my boards in today's mail.

I'm going to look closely at them later this evening. If I can't figure something out, I'll post a query here???

Thanks for the excellent service.

Thank you Gil-Garcia!!!!

I just put my boards together last night using this same parts list on Peter's recommendation. Luckily I did not apply the juice yet, so can I swap the FQA's around tonight. Close call.

Hey Peter are there any of the F5 boards and supply boards left? If so please PM me or e-mail me regarding a possible pick up.

Thanks again, and the LM3875 builds are still ongoing, awaiting some parts.

Hi, I got those diodes two years ago and didn't keep any notes. Tried to identify them recently through findchips.com but that didn't produce any results.

I have approx 36 stereo amp sets left, no PS boards though. Pickup is fine, but since the shipping is already included in the price of the boards, you may as well order them online.
