I haven't tried building this yet, but it looks like one end of the 22nF capacitor is disconnected. I wonder if Depth Sw 3 should maybe be attached to row F rather than row D?
Tag away! This one sounds verified to me - just built it up, and it is, indeed, a treble booster! I used one of my pile of MP42B transistors that measured around 90 and it sounds right to me!
use a 2p6t switch like this one (https://m.media-amazon.com/images/I/51weQCgLKvL._SL1100_.jpg) connect depth sw a to the pin labeled a on the switch, depth sw 2,3,4 to their corresponding labels on the switch, use the ring to set the rotary switch to 4 throws. so yeah you simply connect a wire but not to each pin
I think I'm not understanding it quite right, I connected the depth switch A to the center row (where there are two pins) to one of them, and then the other 3 wires I connected to 3 pins (the outer circle) so 4, 5 and 6 would be left without connecting any wire (and the other row is also empty)
https://www.auselectronicsdirect.com.au/assets/alt_1/AC3152.png?20230512124517 here you can see the pinout of the switch (https://m.media-amazon.com/images/I/51weQCgLKvL._SL1100_.jpg) do not use this one (https://ae01.alicdn.com/kf/HTB1XjUpkBnTBKNjSZPfq6zf1XXaP/2PCS-RS25-Band-switch-2P6T-Mount-Rotary-Switch-Selector-Band-2-Pole-6-Position-Knob-Switch.jpg) they have no numbering so you keep looking and trying for forever ( lots of combinations possible) so get a black plastic 2p6t with a ring so you can set it to 4 throws instead of 6, and just connect swa to a , sw2,3,4 to 234 on the switch, thats it. good luck!

ReplyDeleteHi, I'm a bit new to this. How do I connect the 2p6t? Do I simply connect a wire to each pin, leaving 9 pins free?
