General Questions / Re: Quqdrovibe light bulb

I am completely stupid...I didn't solder the LED...I thought that it's only for bypass, so I put it for a few seconds, without soldering it, on the back of the PCB to test the LFO and after I removed it 
Thank you again Brian for all your fabulous work!

General Questions / Quqdrovibe light bulb
March 20, 2012, 07:47:59 AM
Hello all and thank you Madbean for all your great work!!!
I've just finished a Quadrovibe, using a 14V/40mA light bulb instead of the 18V/28mA requiered (it was impossible to me to find one here, in Bucharest).
The problem it's that the lamp doesn't blink (it lock up or blink a little and fade out after I'm modifying the Gain or Chop trimpot).
The LFO works OK (the LED it's blinking), the signal passes in both modes (vibrato/tremolo), the T1 trimpot works.
I used a 1K trimpot for gain instead of 500 ohms and a 25K trimpot instead the 20K trimpot.
Best regards,
Radu
