    Hello there,
    I have a problem with tremolo in my Tremolux. The pulses are really strongly audible (ticking) if the tremolo is engaged/on (even if there´s no signal from the guitar) and I don´t know what´s going on. It´s the tweed 5e9A schematics but I finally changed the paraphase PI for that of tweed deluxe 5e3 because of better overall sound (as in EC Tremolux circuit – cathodyne PI); if the circuit was the original one (5e9A) everything with the tremolo was OK. After changing the PI scheme the problem with tremolo occurred. All the measured voltages values in tremolo are + or - 20% of the original 5e9A schematics. I´ve already tried to change the tremolo valve for another three but nothing changed). Any suggestions? Many thanks. Regards, Martin.
