ST35 amplifier

this is our new low-powered tube amp, available as KIT or ASSEMBLED


This is based on a popular amplifier kit that sells for $1200, our basic KIT price is $600 or ASSEMBLED for $800. Includes all tubes.
Standard configuration is a pure tube amplifier, with one pair of inputs, one pair of speaker outputs, and a power switch.
Options include a volume control with knob, a rotary selector switch with knob, and a power switch with matching knob, on a custom machined front panel.
The basic kit includes the RCA jacks and speaker connectors, but no holes drilled in the rear panel. A custom machined rear panel is available.
This is a push-pull tube amp using four of the great sounding EL84 tubes, with 6BL8/ECF80 type tubes as drivers. Auto-bias, no adjustments needed.
