As we started to develop skiff format modules (Dtech VCF and Polivoks(ish) VCO), we realized. we need knobs that fit Alpha potentiometers with imperial shaft. So we decided to make them available!
The AS3320 is a high performance voltage controlled four-pole filter with on-chip voltage controllable resonance IC.
PNP matched transistors in DIP8 case!
Famous LM394 matched transistors analogue made in Latvia. NB! transistor configuration is the same, but pins are shifted up - please refer to pdf manual below!
Freshly made in Latvia matched transistor pair, equivalet to LM394! Gold plated pins and metal can TO-5 case!
