The SR-009 is the product of repeated research trip to techology and material search without deviating from our stance to return to live sound and music always with refined sensitivity.
looks like it says its woo audio on the about page.
Here's a few of the Amplifer Case interior.
Signal input is not final. Assembled with a TDK 4CP-2500 volume control from s recent GB. The ALPS RK50 is waiting for me have a machine shop make me an adapter plate (already designed).
Wire from the PCBs to the STAX jack is not final (too short). Longer solid silver/gold teflon wire on order.
Also, to do: devise a permanent Star/Chassis Ground connection. A better solution is needed,
The photo of with the top plate installed is from an earlier trial fitting. Shown with Svetlana Winged C EL-34 (2000 vintage). Even on a short listen, they sounded like "Meh...." Now up and running with a matched quad of JJ 6CA7s. Highly preferred, this amp sings now. Thanks for the tip Whitigir!
Also to note, in the umbilical with the heater wires tightly twisted and all the other wires scramble wound, there is zero, zip, nada, NO hum. Deathly quiet.
I just discovered that this exists: https://www.staxaudio.com/
Must be the new US distributor? Maybe @justin knows more?
009 pads listed for $150. No clue if shipping to Australia is possible from this seller, or how much it would cost. Prices for other products significantly lower than the defunct staxusa.com.
