The faceplate was changed from black anodized to natural brushed aluminum.

The final revision made no changes to the circuitry, only the cosmetics and the layout.

All the revisions to follow would maintain the same controls, but the red power light would disappear when the black faceplate was introduced. Universal 17' Accordion - very good condition (cuntry of origin Unknown) serial 54/3499.
The rest of the design features two black plastic control knobs with silver tops and clear plastic collars, two smaller black and silver knobs, eight black plastic pushbuttons and a red power indicator light. The output matching transformer at 600 ohms was a UA-5002 (later improved to UA5002A) with a split secondary, a tertiary winding for negative feedback to the final line output circuit, and a separate emitter winding.Ĭovering up all this electronic wizardry was a brushed aluminum faceplate with blue paint around the Weston meter. The output amp circuit was similar to the preamp, but followed by a 2N3053 bipolar transistor operating in Class A. The original 1968 design by Bill Putnam used an input transformer at the industry standard 600 ohms resistance (Peerless, later UTC), a T-pad resistive attenuator to drop the input voltage, a FET acting as a voltage variable resistor to control gain, followed by a bipolar transistor as a preamp (the famous 1108 circuit with a Darlington pair).
