Hi pathetic
Mundorf Supreme 1uf Mcap for the I / V that is very good! but not necessary for SSHV, waste too!

Im wrong it, Shunt diodes for low Salas for special, select the type equivalent

I'm not quite clear on this. Do I use 1N5819 or 1N5062 for the DAC updated?
Thanks quanghao.

I have a couple of questions for those who have finished the DAC.

Did anyone try removing the filter (L1,L2 in the DAC and R30-33 in the IVY)? What difference should I expect if I do that?

Also, I'm thinking of switching some caps to Black Gate. The ones I'm replacing are the Sanyo 47uf. I'm having the OSCON SP there and might try the BG NX HiQ 47uf. Other caps are the 220uf in the IVY. Thinking of popping the BG N 100uf into there. What do you guys think about this? Is it worth replacing those caps?

HELP

Problem with Salas HV
Using 0-250 Rcore -260V AC at input

250VDC after rectifier?

Have blown 2 9610s
THe 470 ohm resistors start smoking after 2 seconds. Obviously too much current

No obvious shorts on board.

Where do I start troubleshooting

Thanks

Bob

In my experience 2uF give me a litle thin sound (for comparation); with 4uF (each channel) this problem is in some way surpassed, the bass is more pronounced, more body, more solidity, more color. I take this detail quite seriously.

pharaod, I'm sorry, my reply appeared out of the context.
I wonted reply to the "pathetic" #1940:
"Hey guys, about to order 1uf caps. I'm going to order 2 x 1uf Mundorf Mcap Supreme for the I/V. Was just wondering if I need premium caps for the Salas Shunt as well.(...)"
