Twin Face - Correct Trimmer Adjustment

Well-known member
OK, I just finished my version called ''Two Faced'' & I had the following issue:
1. I dialed the NPN 2 side to 4.5v as described in Notes with a DMM.
2. I couldn't dial in the PNP 2 side at all, It's at full voltage, Sounds Great!
3. Sent message's to Member & Administrator, Both Sleeping as I write.
4. Revisit, Now I'm getting full voltage to NPN2 side & 8.5v on PNP2 side, What Tha F....!!!
5. Ding, Ding, Ding, My Brain Kicking In !
6. You have to Switch the Toggle to the PNP mode to adjust Trimmer for 4.5v to that PNP 2 Transistor.
7. Switch the Toggle to the NPN mode to adjust Trimmer for 4.5v to that NPN 2 Transistor.
8. So if the Trimmer isn't Working, Flick The Toggle Switch!!!

Update : I ended up tuning by Ear in both Modes as at 4.5v it had No Headroom & sounded like a Fart sack!
