    Tremolo intensity on Univox U42/45

    Hi. I picked up a hacked Univox U42. Hand wired, similar topology but different camponent values as U45 and to top it off, someone did a significant hack...swapping the function of the 6AV6 to tremolo osc, and the 12AX7 stage to gain... i got it to work, sounds decent...a bit to easy to breakup, but the tremolo intensity is too deep. Can someone suggest if/where i can install a pot to vary the tremolo intensity. Otherwise plenty of good info on this site to deal with the overall amp tone. Thanks.

    Looking at the schem for the U45,I would try putting a resistor between the output of the osc and the cathode of V1.Try a few values and see if they bring the intensity down.
