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

SRMcGee,
How many PCBs will you have to order for a stereo pair? Usually JLCBCB gives an MOQ of 5 for any design. So for 2 gerbers, I am assuming you will get 5 pairs?

I already have about 20 of the adapter boards in hand that I won't need. the price difference between 10 and 30 boards was about a buck and a half... If you need a couple of adapter boards, Let me know. I think they will mail in a small envelope in the US.
zman01:
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.
Donaldspace:
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.

Scott

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,

No. We decided to leave out the Edcor transformer. It is much larger than the other two, and didn't fit well with the board size we were working with. The store may wish to have a different layout for the F6m with that transformer.
Ok thanks TA. The other transformers are too pricey for me so I’ll see what the store does eventually, time to move on and go build other stuff. Have fun
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.
Update from me - I’m working with my transformer partner to make something more palatable.
Any update on validation of the latest F6 Diamond PCBs?

Ok cool - so the gerbers are final then. I’ve been reading too many posts!
Was there a final BOM as well / Mouser link?
