Would something like this work to power a LCDPS feeding SPDIF/COD/Metronome and Placid BP feeding IVY?

primary: 0-115V-230V

secondary: 15V-0-15V 1A (Center tap)

0-9V 2.22A


Power:50VA
Thanks!
-V

No.

You could use the 0-9v to power only the one half of the LCDPS (only the on half!). Whether this one half is able to power SPDIF/COD/Metronome or not, I don't know. You have to consult the manual.


You can't use the 15-0-15 for the Placid BP. It needs transformer with two separate secondary windings, like 0-15 + 0-15

Are you referring to this? *Please note that one transformer cannot power both a single (LCDPS or Placid) and a bipolar (LCBPS or Placid BP) at the same time, as it will result in a short circuit of the Ground channels.

If so, I am just using one transformer to power a single LCDPS with 9/0 and 9/0. Not a bipolar.

For the Placid, I would use 15/0/15/0 with ground between the two secondaries (the middle two numbers). That would I think give + and - 15v.

LCDPS needs 4 wires from the tranny. 0-9 & 0-9. If you only have 2 wires, 0-9 you can only power the one half.

For tranny for placid you need 4 wires. 15-0 & 15-0. The go to the 4 ways connection block. If your tranny only has 15-0-15 (3 wires, centre tapped) you cant use it.

THanks! So this would work?

15V*2(1A 4 wires) + 9V*2(1.1A 4 wires)

I would step up in current.

Look at the stock trannies.

They are doing more than 1A per winding.
