CGS 116 Extended ADSR - Transistors placement

CGS 116 Extended ADSR - Transistors placement

2012-01-25 by Stephen Richards

Hi Ken

I am about to install transistors to the CGS116 EXT ADSR.

As i under stand the notes on the CGS116 build page ; all 'N' type transistors are reversed as to how the are shown on the pcb's.

Would this mean the LED Driver 2N3565 is going to go in as shown on the pcb and all other transistor reversed ?

Also , these are the replacements i am using for each.

2N5089 - 2N3904
2N3565 - 2N3904
2N4250 - 2N3906

Does that look OK ?

No.

No. Only the LED Driver needs to be reversed. All others are correct for the
type of transistors you are using.
