It's a 0.125" shaft. I wanted to use those knobs salvaged from a very old mixer...

[Zen Mod]

just flip it upside down

 

[peppennino]

Now it's correct

Hi all,
As I'm building a little 24V linear psu for this project, I'm considering to use a second socket to feed the B1R2 (that will become B1T once Edcors arrive) since LT1084 is powerful enough. Is a 16VA xformer a right choice or better go for 30VA? Thanks

 

[Stanislav]

30va always better. If it's a bipolar PSU go even higher, 50va.

 

[Zen Mod]

there is no replacement for displacement?

Mini Cooper got its share of Monte Carlo Rally

so, conclusion - best to have at least 500VA EI chunk, close to those signal xformers


disclaimer - in case of Iron Pre, with Good Gemini regs - there is no difference , as long you use decent xformer with enough VA (10VA)

for Peppennino's build of B1T, dunno what reg is used, so maybe it's best to go with 500VA

 

[peppennino]

oerdered 600 VA

 

[Zen Mod]

well, better safe than sorry
