Anyways You do not unbalance gain with this 332K resistors https://www.mouser.fr/ProductDetail...EpiMZZMu61qfTUdNhG3EzrPz99APhI%2B4G%2BcQ3ZMc=
temperature drifft is little 25 ppm and price < 1€.
No worry about magnetic field influence CMF have no steel inside.
It's far away from expensive ~ 10£ boutique resistor with unknow datasheet

Excellent!!
Now, I have 6 good large Sonicaps and litle warm Mallorys to put in parallel.
This order is so good that I have to find something useful to make 50 dol.
Missing 7 dol for free shipping!
All this for the price of one 2W Audio Note Silver.
Audiophiles, wake up!

I don't remember but... isn't it necessary to have them matched?
I remenber I received a gift from Nelson...
R1 must be 100ohm, right?
@ Polaron
I don't know how much Your four R1's value is ?
Could be possible make Ohmeter mesurements....or simply read color code bars ?
I can't see them very well on the photo.
My boards are for vintage Toshiba not Fairchild so R1 are not on the pcb.

I have all these tools, even CK cutter, luxury.
Braid from Stannol, the best.
I have to ask Nelson if he has a spare set of jets.

Make high quality work with such tools is more handy
🙂Fairchild jfet´s are cheap from Mouser
get some spares for the future
@ Polaron
Yes matched see instructions in Mr.Pass B1Korg article.
Forgot write about this upgrade FN9222S1B-3-06 Schaffner | Mouser France

To bright sounding
I really do not like the Korg. Very very bright sounding. I wonder why. I use a New Class D 24 v regulator.

Test voltage at T7 and T8 are 9.5 V ?
Power amplifier speakers connectors have reversed polaritys ?

I bought the parts selected from Diy Audio. But it measures all to low. Around 6.45 for both. How can I change this?
Thank you very much Sound happy.
