|Now using my newly developed modified Pi wound output transformers for fully balanced DC resistance, AC impedance, and low distortion.|
The new output transformers now measure 20hz to 20khz +/-0.1db.
What this means to you is the output tansformers are not a limiting factor so no design compromises are needed to compensate.
Transformers used in some sub $3K amplifier can measure as poorly as 20hz to 20khz +/- 5db. In these cases, massive circuit design compromises need to be made just to achieve barely acceptable sonic and measured results.
Price for Topaz KT120 as pictured above $2545.00 (built on optional Jarrah Chassis)
Standard model with Tung-sol 6SL7's and Tasmanian Oak Chassis is $2495.00
Based on the Topaz EL34 circuit, the KT120 version runs larger power supply featuring a 900va power transformer and dual rectifiers.
