Title: Old traynor tremolo tweak?

I was wondering if anyone knows how to slow down the tremolo in this circuit , it is too fast and won't go slow enough for me.


Thanks!

I did a search at the traynor yahoo group, one of the guys recommended changing the .01 caps to .02 to slow things down, hope it helps.  I have my YSR open at home, maybe I'll try it this weekend and let you know.

Double the size of all SIX caps. 

Doubling just the 0.01 will run slower, but note there is a 0.015 also. If you lose this 0.01:0.15 or 0.02:0.03 ratio, the oscillator is less likely to start. Also the cathode cap must be "large" at the lowest rate or it will tend to not-start. The 0.02 output cap must pass the lower rate so it should be larger. And "tik" may be a problem, the 0.001 cap reduces that, and may as well be larger.

The 0.01/0.015 caps can be 0.022/0.033. 0.001 becomes 0.0022. Use 0.047 output and go ahead with 100u cathode cap.
