MicDaddy said:duantro, how did you build/buy your switches? Is there a sweet spot for the threshold or is 15-25k log sufficient?

Looking back to post 3156 by Mitsos....weiss said:can anyone help me wire my attenuators? i can't find the corresponding terminals..
and now this is what the wiring guide says:

which relays did you use for the bypass boards?
I'll include a diagram that someone else posted somewhere in the thread. Their values are slightly different than Mitsos is explaining, but it should help some to visualize the layout.mitsos said:I think the actual resistor value for each step is the last value in each line. Kingston says the total R is 15K. It's like a pot/ voltage divider like a volume pot. Signal goes in on top and out the wiper, other side (in the volume pot example) goes to ground, but here the two "pots" connect together and is where the control voltage goes.
Anyway, between the CCW position 1 and position 2, is where the 1191R resistor goes. Between pin 2 and 3 should be a 309R, pins 3 and 4 a 183R, and so on til you get to the end of the each section. Signal would go from the trafo to last pin (CW) of the respective switch sections, the first positions (CCW) would connect together and go to CV and the poles of each switch go to the grids of the valves.
cptpfeffer said:I changed the circuitry of the Time Constant pot to a six pos Switch with a much bigger (faster) timing range possible. I completely took the 10k Pot and the 10uF cap out and replaced it with the 6 pos switch. One end goes directly to the out of the two diodes from the controlvoltage rectifier. The other one goes to the middle pin of the attack socket (wher the pot normaly is connected)
Pictures attached. the timing range goes from 10 msec to 0,5 seconds. I was smashed away by the achievable soundresults!
