> Does anyone have a datasheet or pinout for a UPC1330HA? There's a PDF Sony service manual online which has this IC on the schematic. It's at: https://www.vancebaldwin.com/shop/research_new/SON/HCDMC1.pdf I've attached a pinout diagram of the IC itself from it. Here's the pin description (may be confusing, but this is how I got it): Datasheet text preview: UPC1330HA ***** AUDIO HEAD SELECTOR -SIDE VIEW- IL04 1 SW R1 GND 2 3 SW P1 4 CONT VCC +4.5V t o GND +15V) 5 6 7 ( GND 8 9 SW R2 INVERTER SW P2 COMPARATOR 1 SW R1 2 GND 3 SW P1 4 CONT 5 GND 6 VCC 7 SW P2 8 GND 9 SW R2 If you have a login at bdent.com, they seem to have a spec sheet for it. Hope this helps. William E.
