The 68 ohm resistor connected to Switch 1 should be 10 ohms, according to the schematic at any rate.
Also, the schematic has a DPDT switch that, in position 1, lifts the 470K feedback resistor of Q2 and bypasses the 27nf capacitor, while position 2 is what's hard-wired here. If you want to try this, remove the jumper at 18E/18G and connect the DPDT like so:
pin 1: n/c pin 2: 18E pin 3: 18G pin 4: 18F pin 5: Tone 3 pin 6: 18D
i built it and it works, you can verify it! thanks!

Yes, SW3 toggles between Spacerocket V1 and V2. The layout is for the V2 version only.
DeleteApoligies. The 68 ohm resistor should be _100_ ohms.
ReplyDeleteFixed.
DeleteThanks for noticing.
