Discussion about the Korg PolySix synthesizer

Hi,

 

It’s a Hamamatsu P1501 Dip 5 opto-coupler device. Try here
http://www.chinadatasheet.com/download.asp?id=1376323_852681. This device is
older than the hills and probably obsolete. The resistance across pins 4 and
6 should drop as the voltage across pins 1 and 2 increases (I think!!!).

 

Cheers,

Andy

Subject: [PolySix] PC-1 Optocoupler question

 

  

Hi

I was wondering if anyone has a datasheet or pinout for the PC-1
optocoupler, i'm thinking mine is broken but i can't verify it as i can't
really discern the pinout from the schematics.

Thanks!

Karl
