bingo
my dear Papa's Koan (first of them, F4) is made in similar fashion - had 800VA Donut with 4 secondaries , 18Vac each
then 4 bridges and separate cap bank for each channel
FW case being too sissy to squeeze in motor runs too ....., but- hey , that could be squeezed only in 500mm deep
edit : so , 800VA Donut , sum heat being around 150W , and singing all day long with peaks at (2x) 1W5/16R , in my workshop
but , I've put LED toobz , instead of neon ones

When you mentioned that the Singing Bush had a bias circuit requiring a lower voltage, I found an.ANTEK 1000VA xformer with dual 48v along with 18v and 12v secondaries, I went with it instead of having to find room for multiple xformers.
I'd rather have room for capacitors instead of xformers.
Thanks for listing spec's for PS, I was hoping you'd list your recommendations.

Could you post a rough power supply diagram with labels? I know it's a work in progress.
asking elwood , or me?
Hi
I want know if is possible use linear amplifier as replacement transformer input JENSEN .
https://www.vishay.com › docsPDF
Designing Linear Amplifiers Using the IL300 Optocoupler - Vishay
ZM is possible in isolation galvanic T and 4N37?
not possible without major changes in circuit - input xformer is necessary part of Schade feedback loop , doing several things at once ( all explained in Papalecture , linked in first post) - galvanic isolation , Schade feedback , increase of input impedance
if you can find decent 600:600 xformer locally , try it
decent means - declared HiFi use ( 20-20KHz) , not Telephone range

Well, I guess I have some time for the project.
Here is the first power supply.
Nice, with LT4320 ideal bridges
