"I saw this SEM SUB-oscillator floating around the internets and had to give it a go. 5 stars would go again. Available here from @Lackan110f https://reverb.com/shop/peters-gear-g..."

Note the Marion Systems logo on the board. As readers of the site likely know, Marion Systems was Tom Oberheim's follow-up company after Oberheim.
"SUB-oscillator module for the New Oberheim SEM Pro (2009). Installation is very simple, you just have to solder one wire to the +15V point and then attach three connectors.
The +15V point can be located in various places depending on if it is a Marion or Oberheim, and also what model it is. So a multimeter is recommended to verify +15V.
This will give you a -1 octave SUB-oscillator using the EXT-IN knob #1, or a -2 octave SUB-oscillator using the EXT-IN knob #2.
You can also mount it so that you keep EXT-IN on #1 and have SUB -1 OCT on #2 (SUB -2 OCT is then omitted). Se illustration.
Does NOT work in an older vintage SEM (1974-1979) due to different connectors. (the video shows a vintage SEM, but this product is for the New TOM SEM Pro 2009)"
