With both a 230V Normal bias and a 580V Pro Bias output, and an output voltage of 370V, this amp will properly drive any Stax earspeaker on the planet, even notoriously difficult loads such as the Sigma, 4070, Omega I, and Omega II.
Condition is very good for being vintage, only a few minor scratches on the external paint. Amp was re-tuned and serviced for typical vintage amp maintenance only a few weeks ago, and had its capacitors (which had dried out due to normal aging) replaced and upgraded at that time, so no maintenance worries whatsoever. Many other vintage Stax amps you will find have never has this essential maintenance performed, so be aware of this.
Input voltage is currently set to 117V, but can be set to whatever you like before shipping, just ask after you buy.
Amp comes with two different data sheets regarding both the SRM-1/MK2 pictured, and the SR-Lambda Pro that often came packaged with this amp back in the day. Amp also comes with a 117V power cable suitable for use in the US, and the RCA cable pictured.
Buyer pays shipping and PayPal fees.
