    I was wondering if anyone knew where I could use the MSD6150 transistors that I have laying around in the circuit. I heard that they were used in the original GR circuit, but I’ve been unable to track down a schematic that uses them.

    Thanks for your help!



    The MSD6150 dual diode is mentioned in these RG Keen schematics it’s common anode the one on the left shows it, note the anodes are connected to Q3 whilst on the right the cathodes hence the update I’m assuming
