EHX Y-Triggered Filter Gut Shots
« on: April 19, 2018, 01:02:09 PM »
Hello,

Does anyone have some gut shots of a 1970s EXH
Y-Triggered Filter? I know other members have posted them in other posts but they are not showing up as if the link to them is broken.

Thanks,

Ryan

Here's a pic of mine.  Note that the twisted pair of yellow wires go to a toggle I installed on mine, and aren't stock:

Thanks for the pics. The one I'm working on is slightly different. It has 4 transistors.

2N5088 & 2N5087, EHX regularly switched between those and BC309 & BC239 though so it may vary from unit to unit.

Hey Scruffie

Would you be able to get me the voltages on the 4558 ICs?
