..of course knowing that u ain´t sleeping
do you still intend to leave an option for the lazy ones to make resistive pot ironpre
nothing is stopping ya ......... cheap xformers are everywhere , and you already have all necessary know-how
Thx. Now I can do my own math.
Btw, don-audio.com not only sells the PC type Edcor transformers
https://www.don-audio.com/Edcor-PC600-600
(0.25W, 2.5H as stated on that site)
but also the PCW type
https://www.don-audio.com/Edcor-PCW600-600
(0.5W, 2.5H)
and the WSM type
https://www.don-audio.com/Edcor-WSM600/600
(also 0.5W, but 3H)
at almost the same price.
Will bigger transformers have bigger sound?

I always like the idea to make everything simple, i read somewhere that if volume pot is fed with higher input like more than 5V is not good. once I had tkd 2cp65 which I thought as ultimate volume control but after long reading that idea was abandoned, sold it and just use tkd carbon. Thats why I always try to look at several options to get extra gain from preamp, with pllxo biamp I have already lost some headroom. Luminaria is the option now with parts is ready to be soldered.
but this thread is very interesting, which brought me to Slagle AVC which looks interesting. my AD1865 dac with srrp has 2.4V output and I have unused sowter 9762, and another AN dac red pcb that i have populated but too lazy to reworked existing dac. I might put sowter and use parallel tap and match with Slagle of 8V input capability, and I might not need another active gain stage
is this good option to pursue with 8V dac output + avc? is buffer before avc really required?

Supermalloy = better permalloy ?
Hi write perfect wave form but they don't look like one "perfect" square wave response btw...

tube SRPP ?
for proper drive of AVC you need cojones , and tube SRPP is not having them
however - buffer and Slagle AVC (fed to -6db point , old type , not modern ones with two switches)
It is better to use low noise and low losses C-core like F3CC or AMCC
any tips for source of these ?

yes tube srrp, its look like AN dac2.1, previously i wanted to pursue on building AN dac4 but building several class a is more interesting.
if i understand correctly, i still need buffer and I can put Slagle on buffer output without any need of passive volume pot before buffer, correct? I'm using dcb1 now, you use k170/j74 as source follower, any hint the difference with dcb1?

stopped following buffer threads long ago , so remind me - dcb1 is direct coupled B1 , meaning of first iteration B1 , with 2 x 2SK170 ?
regarding Rout , complementary JFet buffer is superior , having half Rout , vs. noncomplementary one .... and for drive of chunk of iron , every Ohm is important
also , THD spectra is ......... matter of taste
try dcb1 , so - signal source , dcb1 to AVC , tapped to tap which will give you desired gain
regular pot is redundant .......
if you like what you hear , you can try other type(s) of buffer
