ok, earlier than tonight
how to add Edcor 600:15K to Iron Pre preamps, both SE and Bal;
SE - to have additional 6V/V (almost 15.6db) of gain
Bal - to have additional 5V/V (almost 14db) of gain
note: see on Edcor site - 2 different wattage options of said Edcor; weaker one ( used in M2) as proven, stronger one (more lamms) for lesser THD when swinging high

bare with me - I did use female XLR sketch at first, by mistake
later edited to write male and blackened pins
take care of pin numbers, not notch triangle shown; anyhow, I'm never caring for notch in vivo - always looking at number of pin

Ok, I hear you. Maybe in future. But time and finances are lacking. I would love to build more PapaCreations™.
Wow, thank you! Now that would make a nice wall poster in my living room (read sound room). 👍
Zen, how do you do it??? 😎
"We are not Worthy!"
I bought the 1/4 Watt. Will have to check if there is more 1/2 Watt maybe I'm guessing??? Is there a limit?
I have no excuse not being able to implement your ideas in the Pre.
Will be glorious
M2 coming in queue. After F4 and Gen 1 Sony VFET pairing.
Can't go any faster... Maybe it would have educated me for the Iron if I finished the M2 projects earlier?
Ha! You coming up with these circuits? I can restore/build vintage aeroplanes, race cars, heavy iron, and make sawdust but you can corral electrons.
naah
I'm just stealing those from Papacoral
Papa's
are
most free
electrons

Still, it's like herding cats. Squeezing them into line and making them sing. I am in awe of your ability and of your mentor.
I hope you don't mind, ZM. I tidied up the thin lines in MS Paint to be more consistent and completely white.
If you zoom to 100%, you'll see what I mean.
Thank you!

there is a thought - A2 or A3 size , Kunstpapier Poster, DiyA Store

Just for fun - some color. Can also be used as a Christmas tree. 🤣
I don't know if this has been covered. Mouser is out of 24 VDC Relays. I ordered 817-RY-12WFZ-K 12 VDC instead. Are there any changes needed to accommodate?

just zener diode in relay reg
whatever relays voltage is, said zener is 4V on top of it
if going down from 24Vdc, put small hsnk on mosfet

Zen, I see you have planned, looking at board, for eventual bombs with diodes before the relays. 
Do all the mosfets need heatsinks? Or, just M3 with relay V drop to 12 VDC?
Danke, H.
