The Tilt-2 Control kit consists of a small PCB (1.4in by 2.8in), a stereo, shorting, three-position rotary switch, four capacitors and sixteen resistors. It is a passive design, which entails a -2dB insertion loss and whose center frequency is 600Hz. The center position results in a flat frequency response, but is down -2dB. As the control twists clockwise, the highs go up by +1dB and the lows go down by -1dB per click. Conversely, as the control twists counterclockwise, the lows go up by +1dB and the highs go down by -1dB. Kit includes user guide and the PCB, rotary switch, and all the polypropylene capacitors and 1% metal-film resistors.
The PS-19 is a regulated bipolar power supply that puts out low-voltage bipolar voltages between +/-5Vdc to +/-24Vdc. It uses an LM317 for the positive output and an LM337 for the negative output. The PS-19 PCB is only 3.7" by 3.2" and, like all GlassWare PCBs, is extra thick (0.094 in), US-made, with heavy 2-ounce copper traces. The rectifiers used are ultra-fast MUR410G types, each of which are shunted by a 0.1µF ceramic capacitor to reduce RFI creation. The power supply requires an external power transformer.
