Suggestions for BJT Tremolo Oscillator

[makinrose]

Hey everyone I'm looking for a good BJT oscillator circuit to drive a LED LDR or Jftet. I'd prefer the LDR.... I've used the London Power Wide Range Tremolo in a  tube amp and like it but since all my stuff uses eyelet boards I'd like to find a BJT circuit to do something similar. I find discrete components easier to wire up.  There seems like a multitude of circuits out there. Does anyone know of a good design to start off of? I figure I can derive the voltage from the high voltage supply and use a Zener to get the right voltages.  Thanks for the help!
