Pass Labs X2 REV1 Relays?

Mad_K · 8th June 2005, 07:40 PM

Does anybody know what make/model/type of relays was used in the X2? (RELAY1 & RELAY2)

It's just a guess, but I think it's this one: http://www.diyaudio.com/forums/attac...amp=1052926903
Same as is used in the Ono. I thinks Pass likes to buy big and use the same components in many of his products. Makes sense.

Cloning an X2 are you? Any plans for making pcb's? I'v been planing on upgrading my preamp, and X2 seems to be a good candidate.

We consistently use Aromat DS2Y-S-DC24V. The relay
pictured is a sub made by Matsushita. Very nice relay.

Good guess! Thanks. Yes, I'm cloning an X2, and I will try to make as good a replica as possible, down to the pcb layout and component choices. I also feel the X2 to be a good candidate

Thank you Nelson! This works out very nice, as I had figured I would use Omrom G6A-274P-ST-US-24, which is compatible. It just has a little lower coil resistance 2K88 instead of 3k2 for the DS2Y.

Does anyone know why R13 (4K7) has been added to the output of the -32V regulator in the X2 REV1 PSU?

That is an SDS number.
Aromat is Panasonic, Panasonic is Matsushita.
SDS now being NAIS, or Matsushita if you prefer.
Matsushita has used licenses from SDS for decades, the S in SDS from the founder and relay designer Mr Sauer in Germany.
Ever go to Japan and you'll discover how big companies as Matsushita and Mitsubishi industries are.

The SDS DS2Y i started using 2 decades ago, it's a joy observing NP knowing the hardware so well.

Yes, they can build you a nice little relay, a flat screen plasma TV or a high tech oil tanker ship...S. Korea is following suit.

Gents,

Forgive my ignorance - how did you find the X2 schematic ?
I thought it was still "secret" since still in production ?

Hello Wayne
The X2 is no longer in production, and the service manual can be found on www.passlabs.com under downloads.

Cheers !
