For sale is my DIY KGST. I built it for my own use. Selling because it has been collecting dust on the shelf lately and it deserves a loving home.

The outside dimensions are 240Wx89Hx320D, or about 9.5"x3.5"x12.6", not including the bottom bumpers, the volume knob or the RCA connectors. The unit weigh 12lbs. Being a DIY product, it doesn't have any engraved or laser-marked lettering. The asking price reflects that as well.

The front Stax-compatible headphone jack is for Pro bias only (580V). The rear panel has balanced and single-ended RCA inputs selectable by a toggle switch. The extra pair of RCA jacks are not wired. The AC input is rated for 115V (110V or 120V okay). Being a class-A tube amp, it runs quite warm. Please leave ample space around it for heat dissipation and do not stack any other unit on top.

The 6S4A tubes are matched on a curve tracer across the entire working voltage
and current ranges for lowest distortion. The circuit has been tuned to extend the undistorted output voltage to >400Vrms, ready for low-sensitivity phones.

The asking price includes Paypal fees and ground shipping to US lower 48 states. Please feel free to ask any questions. Thanks.
