Power supply, input potentiometer, resistors, capacitors, zener: all will be the same except for the Jfets. There will be A-B hardwired switchover of source and power amp connections between the two units for instant comparison. Gain matching with pink noise and calibrated measurement microphone.
Question:
Can we use Dale or PRP 0,25 watt resistors instead of the 0,4 watt?
because i will order now the values 😉

How critical is it to use 332K versus 330K resistors? I am trying to build another Korg, exotic resistors are in abundance for 330K and not 332K which is only available in CMF55.
I go with Vishay Dale for now (mostly RN55....learned that from 6L6) but where is your source for Takman? ….HiFiCollective?
When I read how Takman Rex and Vishay Dale RN55 are made they seems quite similar. I have not been able to find out which material RN55 use for the end caps. Takman Rex use brass. Both use copper lead outs and Chrome/Nickle alloys for the element.
Some components seems to have lead outs with some iron in.....else they wont be magnetic I guess…..I suspect it could be some of the small diodes. The lead outs are thin but feels a bit hard to cut.
Hificollective or Partconnexion. I think Dale is a little hard sounding in compare.
Try with a strong magnet. Prp is also unmagnetic but is the worst sounding off them I think. This is from hearing when I was a bit younger. Now I do not think I would be able to hear the difference anymore. Or maybe because I do not try

Nice implementation, Marra! I was considering going the LDR route as well - I have a few sets and a dedicated 5v regulator board sitting in my parts box still. For now, I'm using a $20 Chinese 50k stepped ladder. Perhaps I'll wire up the LDR at a later date and see how it compares...
Balanced output buffer for Korg Nutube.
Aleph 1.7
Pure Tinned Polypropylene 5.6 uf for output. The input cap is at the Korg. Multicap 5 uf Pure Polypropylene 5 uf.

Thanks guys.
The LDR board was from a GB organised by dvb-projeckt some yearsago with the consent of George Strantscheff.
Hi everybody. I have a pair of top Jensen JT-11-BMCF around. I'm considering putting it in use to get the phase back before amp... Any thoughts?
