You may get the bug to do the full blown IP with all the bells and whistles 😀😀

That would be the next logical step 😀
@peppennino - Are you asking about Iron Pre or Iron Pumpkin? If Iron Pre, PM me. Jim (6L6) will likely have you contact me anyway, and he's a busy, busy guy. We can take out the middleman. 😀
EDCOR 600:600 phasing issue!!

which is found just lately - I need to rework all pcbs involving named Xformer, which means Iron Pre too
if you intend to use Jensen or Cinemag, no worries, but there is a price for error in Edcor datasheet
if you already have pcb and intend to use Edcor - cure is easy - either some xacto knofe work on pcb , or same on xformer (swapping pins 5 and 7)

Maybe a little batch of that new beta PCBs in EU would be great, since I have difficulties in obtaining it in Italy...
Or, at least the gerbers, since I don't have the skills to develop

Once again I listened to ZM, and once again it has paid off. I picked up a pair of 600:15K edcors to put after the AVC in my Iron Pre. Works like a charm, and sounds fantastic!! Still need to permanently mount, but so far so good. The cherry on top is that I put them on a switch, so passive/no gain is down, and big iron gain (Edcor) is up.
I’m pretty sure I’ll never need another preamp. Thanks again ZM!!
How many times I thought, "last one.". I don't even get Done before I start another!

I'll make necessary edit of pcb files, both SE and Bal and post to whomever is willing to make small batch, of course with Jim's blessing
Ah-choo!!! 😛
Blessing.
There. Happy to make a run if anybody in interested in trying and testing that it all works. Or if somebody else wants to have them made, please go right ahead.

Any way to get these pcb's in Europe would be greatly appreciated. As peppennino mentioned earlier acquiring one for interested builders is rather difficult.
whenever you are ready, I have pcbs edited ( Edcor issue) and Gerber files ready
besides sending them to Jim (6L6) ......
in fact , I'll send them to Jim, you pester him

Who wants the revised PCB ? I’ll get a run made and send them out, but you have to actually build it in the next couple of months…
PM me, don’t respond in the thread.

This is one nice preamp to have. I have the 2016 board version I built as a beta test offering. Not only is it very nice sounding indeed, the entire package is to be applauded. Power supply, a nice shunt type, relay switching with ultra short paths to the RCA jacks buffer and all on one simple board. No wondering what power supply, all here on one board. Wiring greatly simplified.
You wont regret this little jewel!
