Hello,
I just finished my second Pultec EQ and now I came upon this little problem. Let me explain: for the 3k to 16k frequency rotary switches I used two Grayhill switches (rotary type 1P-12pos 2 deck) with digikey part number GH7103-ND (http://www.digikey.be/product-search/en?x=0&y=0&lang=en&site=be&KeyWords=GH7103-ND).
Now I finally finished my Pultecs and just used the switches, only to find there is a problem with one of the switches. There is no connection between the two decks and therefor the switch is not working at all. It seems now that it is bypassed. First I thought it was a bad connection, because when I turned the switch there was a lot of noise and the, let's say boosted 3k would fall away and come back as I tapped on the switch. Then I turned the switch for 1 minute and it got better, but today the switch is not working anymore at all. There is no noise when I turn the switch and when I boost 3k, or 5k, or whatever, there is nothing happening.
When measuring the good switch on my other Pultec, there is, of course, a connection between the two decks, but on the bad switch there is no connection at all.
Anyone any thoughts on this one?
Thanks a lot!
