Ok great advice, i have checked the voltage at the jack leads, its zero, at the taper pot the voltage is 27 volts, also the voltage at the test switch is 25 volts, i have checked the polarity on the diodes and capacitors and they appeaer to be ok by the eye, i am working to a different schematic to the 1 that you showed me, mine is much older version.
This page above is the schematic i have using and as far as i know its supposed to work as its the original 1. what would you advise as the next step, i really appreciate this, sorry i did not get back sooner but its 5am here and now i am wide away and working on it, what do you need to know next?
