Gold said:Yes, sounds like the relay is working. When you say the HF section doesn’t work do you mean no signal or the controls aren’t working?
weiss said:Is it possible i used the wrong potentiometers? Mine only have 3 solder lugs instead of 4 printed on the pcb. But then i think it's strange that most of the pots work..
i used this BOM
Wrong. Every connection to the ground plane is hidden.shot said:It should be okay to use 3 lug pots since if you observe original board designed by mr. Porter it uses only 3 lugs. Fourth lug is not connected.
I've attached PCB Tracking.pdf here so look it up
Gold said:I used the two 5K resistors twisted together trick to get my EQ going. You could also rig up an On-Off-On toggle switch for max gain, min gain and no gain.
The gain control is a good candidate for a rotary switch for this reason.
