Korg Nutube with New Class D 24 v Supply. Followed by Aleph 1.7 with passive supply. 20.000 uf /Channel followed by 56 ohm 200 MH. Then 6.000 uf. And 56 ohm resistors and 6000 uf again. Should I use a 49 vac or a 55 vac transformer. This would be a passive supply. Or should I rather use the Supply for Bozoz with regulator? I think the passive supply will be the best choice??? Current consumption 70 ma or channel.
How is this possible. Seperate power supply a with seperate transformers. No connection to enclosure. Could it be between thoose Hammond's right after the rectification? Are they to close?
Problem solved.

630 MV AC at output on both. Must be oscilating. Shall I start with removing the 9.1 v from input? 61 Vdc in for both.
schematic could help , as explanation what you are doing
all I can see is relatively lousy soldering job , and usage of audiophool parts (those film resistors) in completely non-critical position

I use filmcaps in series with signal. Can not be uncritical. I will try the 220 ohm at input. I am sure there is no faults.
I measure aprox 630 mv AC on both outputs. Everything else is ok. Current for each board is the 70 ma. Voltage is 61 Vdc. I use ClCl CR.
inputs grounded , and 630mV at outputs ?
do what is already done with previous builds - either add resistance at inputs , or remove zeners , to prevent oscillations ....... everything already covered
if possible , confirm behavior on output with scope

3.3 k and 10 k input resistors.
Thinking of shorting the 10 kohm and cutting the 3.3 kohm. Would that be ok? I have 100 ohm in series with input.

Hi in my 1.7 I would like to use this fantastic capacitor at input. One of the inputs in each channel are shorted to ground. How will it work if I use this in the fase that is not shorted and leave the other with the terrible Panasonic MKP? I also thinking to use Kasei Electrolytics because there is only 3 Vdc at the input off those boards.
what exactly does make that capacitor "fantastic" and the other one terrible?
p.s. for Wima's I used on my board at least the manufacturer provided measurements over the full audio range so one could argue that there was something in the way of documentation; (not to say that that makes them any better or more "fantastic" than those Papa used in the commercial builds).

Something as simple as the way it sounds. Have you never discovered capacitors sounds different. Now I am hoping for a answer I can use.
Hi,
I would like to start adventure of building this preamp 🙂 I was thinking of getting boards by kk-pcb.com however some people complain about them. Are other layouts (like Koja's or Veteran's) better and available?
