What are the differences regarding SST02?

Thanks,

I have made adjustments for 110 VAC. C1 and C2 (the black caps) are changed to 680 nF.

PA:

Are there any practical limits on the SST03 in terms of the wattage of the transformer? In other words, are its traces able to handle a 1000 VA toroid?

Regards,
Scott

Yes, 1000 VA is OK.

I'm closing this offer in the beginning of April so hurry up.

With the low quantities on the GB, is this still a go? I just found it and am definately in for 2 boards and connectors.

peranders · 29th March 2011, 06:35 PM

I haven't decided yet. 12 pcb's aren't much.

DaveM · 29th March 2011, 07:30 PM

Have you posted the existence of this GB over on the Pass Labs page? There might be some more demand from there. That is what I could use them for. 750VA 18V primary transformers for F4s right now, but Aleph AX in the future and then who knows what. I am building seperate power supplies that I can use for any of Neslon's ~22 V rail designs.

I avoid cross posting, no I haven't.
