Folks:
I apologize if this question has already been addressed: I'm thinking about ordering F6 Diamond pcbs (as well as ZM's 4th version of his adaptor board) from a fab house and was wondering whether there were any suggested "upgrades" when ordering these boards. For example, is an Outer Copper Weight of 1 oz. adequate, or should it be increased to 2 oz.? I'd like to keep costs down to the extent reasonable, but don't want to foolishly spite myself.
Your guidance is appreciated.
Regards,
Scott

1oz is overkill for signal purposes
even for power routes it's more then enough, if adequate width of traces is used
Mighty Moi - even prefer 1oz for signal, 2oz being too chunky
alas, when I'm forced to use 2oz pcbs for signal, subconsciously it forces me to use M24 screws for grounding

Yes. An order for JLCPCB's minimum quantity of 5 will net me 5 pairs at a delivered cost of just over 43 USD (using the slowest delivery option and not including tax). A friend wants an F6 and, given that the Jensen signal transformers are unavailable, building this Diamond version with CineMags isn't just an opportunity, it's also the only option. I already have a dual mono F6 and don't need another, so I may sell off some or all of the remaining pairs if I can find a safe and cost-effective way to package them for mailing.

A kind offer -- thank you! However, it seems the updated version of Mike and TA's F6 pcbs don't require ZM's boards, so there's no need. But the kindness is appreciated nonetheless.
I'm still refining the BOM for this build and need to run the expected cost (about 920 USD in total, including FPE's processing of the front and rear panels) by my friend. I helped him sell a tricked-out F5 Turbo last year and he's hungry for a replacement amp, so the odds favor another project for moi. Goody!
Stay healthy, everyone.

Is LM4040AIZ-10.0/NOPB (https://www.newark.com/texas-instru...-to-226aa/dp/33AH4201?ost=lm4040aiz-10.0/nopb) a suitable replacement for LM4040CIZ-10.0/NOPB?
Thank you,

and Edcor 600:600 is having 600ct secondary, not two separate 150R ones
I will say that the F6 Diamond with the CineMag transformers and IXTQ75N10P Mosfets is an outstanding amplifier, well worth the price to build one. I have been listening to an early Threshold CAS-2 and a pair of Cary SLM-100 monoblocks lately, and the F6 holds its own or better, even with those more powerful amps.
The Edcor model under consideration was their PCW tri-filar series in 150:150:150 winding. It is a 1/2 Watt model, which makes it larger.
