Really looking forward to reading impressions on the new amp boards. I love how clean HeadAmp gear always looks.

It's coming along nicely, even with screw heat sinks.

Will the new amp modules fit in the GS-1 and GS-X but not in the GLite?

The Gilmore Lite doesnt use modules

Does the GS-1 have a secondary primary so the voltage on a 110V unit easily can be changed to 230V?
post #321 of 540

No.

Yes

Some stats on the new modules:

 

Max volts peak to peak into loads:

No load - 23Vpp

25 ohms - 20Vpp

10 ohms - 14Vpp

double this for balanced out.  Note that these results are with the power supply voltage increased from +/-16.4V to +/-20V.  Use of these modules in an older GS-1 or GS-X would have accordingly lower output voltages.

 

Distortion (1khz @ 1Vrms)

No load - 0.0011%

10 ohms - 0.004%

 

Freq response: -1dB @ 50KHz

 

I will re-measure the old modules to offer a comparison

The prototype heatsinks for the new modules are in, now I can finally see how much I can turn up the juice.

 

 

700

 

 

I may call it the "Dynalo+".  It's inbetween Kevin Gilmore's Dynalo and Dynahi in terms of power output and design.

Jumper a post board rework or the bias resistors?

there isn't one.  but an existing GS-1 can be upgraded with the new modules.
