Here's some pics of my B1 before and after installing the SSLV, and a closeup of one of the Jupiter output caps.

That Jupiter is their current brown skinned higher temp line. Use something like Multicap in the Zobel.

Default Dual Polarity Salas

But even that complication is not always required.

Simply build all -ve regulators and use a dual secondary to power the regs. This gives an equal or better performance Dual polarity regulated supply than having to buy specialised +ve & -ve PCBs and having the problem of "left overs".

Hi Andrew / others,

Newbie here : I am building two Salas boards to create -12v 0v +12v output to power an Opamp.

Can I 'just' connect the 0v from the two boards to create a reference 0v ? or will I get current drawn from one to the other (ie: short circuit situation).

I have only single transformer 15 output to feed both boards.

Thx
Jim.

Hi, I kept building 3 boards in a row . My boards power TP's Opus DAC and the transceiver board. As a Vref cap, Oscon was replaced soon. Weren't a good choice there. SSLV1.1 works well, I like it very much! C105, C103 caps are Nichicon Muse KZ's: 1000 uF/25 V and 47 uF/25 V.

Thanks Marra,

My transformer is dual secondary, feeding 15v to each Salas board. I get nice 13v output from each board.

To make a dual polarity PS, I assume the 0v from each board should be made common (?). Should the common 0v also be grounded ?

If your client circuit board has a common point, there they go the F0 S0 wires from both boards and they make a symmetric system. Grounding to chassis or not its a matter of how your design is sorted out and what is recommended, i.e floating or not there.
