Put me down for a new GS-X.  What are you calling them anyway GS-X rev.2?  

 

What's the ETA on these?

just GS-X for now.  I'm hoping to have a final one ready for RMAF in October.

Hey Justin.  For the GS-1 can you please tell me how many watts there is into 60 ohms cans vs. the module?  When the time comes, how do we go about ordering one?

I'll want new modules.

 

Possibly a new replacement silver GS-X as well, because even more output power would certainly be nice. Unless, of course, I can send mine in to be upgraded however it needs to be in order to support the highest power capability (I'm guessing you modified the PSU as well?). But if existing GS-X units can't be modified, I'll probably want a new one.

 

Btw, how about either Dynamed or Dynamo, instead of Dynalo+? tongue.gif

I vote for "Dynamo"

the power transformers in the original GS-X are too small to support both the higher voltage and higher current in the new modules (so you'd just get the benefit of higher current).  the next size up in that transformer model is too tall for the enclosure.  So, I am switching to chassis mounted transformers that are 66% larger than in the original amp.

Is it possible to update the trafos in the GS-1 to get the full benefit?

Shooting 0 for I forget how many but... no.

So what will the dimensions be for the new GS-X?

Not sure how you're immediately jumping to the conclusion that there'd be a change to the GS-X enclosure for the updated PSU. Justin mentioned chassis-mounting the transformers as his solution for larger transformers, not a new enclosure. (Justin is also the kind of person who would say if there'd be a change to the enclosure, so you can count that out.) In the old GS-X, the transformers are surface-mounted, which you can see here: http://www.headamp.com/home_amps/gsx/images/gsx_psu_inside_med.jpg

 

Chassis-mounting sounds like a clever solution to me and is probably way more cost-effective than ordering new enclosures.

 

This is an example of a chassis-mounted transformer btw: http://www.headamp.com/electrostat_amps/kgss/images/kgss_inside_large.jpg

 

This internal pic of the GS-1 should answer that question too: http://www.headamp.com/home_amps/gs1/images/gs1_silver_inside_med.jpg

True that.  I was mistaking,  When I talked to Justin at the DC meet he said something to the fact that:

 

Now this is from a poor memory.  

 

The finish on the new GS-X would be the same as the BHSE.  Justin needs to confirm.

post #387 of 540

Maybe the same case before being worked but different front and rear faceplates.

What about me?

yes, if i have anything besides my prototype set of new modules.  the transistors for the new modules arent supposed to ship until 9/28, then figure about 2 weeks for assembly + shipping both ways

The new GS-X is the first ever SS amp that has grabbed my attention - looking forward to seeing more.
