Hey there. i have here a vintage deluxe electric mistress. it was given to me a while ago and last time i checked i believe it is a 1977 or something like that, not totally sure.
anyhow when i first got it it came with no power adapter and has no mattery hook ups. back then i didnt know that if you hooked up the voltage polarity wrong you could fry the unit. so being stupid i tried every adapter i could think of in every polarity and could never get it to make a sound. the power input was a 1/8″ jack jsut like the small head phone type. the only sound it would make was through the direct out or the flanged out if the unit was switched off. so anyway many years and alot more electronics experience later. im trying to ressurect this pedal. ive seen all the schematics on various sites for various models and the one the closest matches my unit is this : http://www.generalguitargadgets.com/index.php?option=com_content&task=view&id=123&Itemid=26
if you click parts layout.

however there are some differences. 1. mine does not have an 18 volt transformer. 2. my unit has a direct out as well as a flanged out, 3. none of my 1/4′ jacks have anything connected to the grounds, only the tip connector is connected to my board if that makes any sense. and 4. my unit does not use a 6 pole switch for effect bypass, it uses a 3 pole standard stompy type switch lol. there could be more differences but im no expert when it comes to schematics. but my looking at this and testing most of the caps. resistors etc on my board they are the same.

now, after looking at several schematics. and what not i have come to the conclusion that this pedal takes 18 volts. so i chained together 2, 9 volt batteries to get 18 volts and connected the pos and neg to the corresponding point on the boad according to the diagram i posted up top. and i got no sound initially. i re wired my jacks to the board as per a picture i saw on ebay of an 80’s model board, and still got nothing. now i have wired my jacks and switches to the board as per the diagram i linked, and now i get sound!, but its not a flanged sound. its my sorta faint guitar sound with this clicking sound when the effect is on. and after some experimentation the clicking gets faster or slower if i turn the rate dial up and down. the color dial has no effect and the range dial seems to add some what of a doubleing effect on the clicking. so i am hoping this clicking is maybe a good sign that the pedal can be salvaged. sorry for the lengthy post, but if anyone has any ideas or could help me through this that would we be sooo awsome. thanks!
