Folks,

I just wanted to share my recent leap of faith with unverified VFE Project. It's called Whirlybird. It's based on Wurlitzer Preamp. There are four controls that I can tell

Level = C50k
Depth = B10k
Speed = A10k
Tune / Trimmer =20k

I've found the trimmer only works slightly. I might have a chance to debug this later on for the v2. Overall the boards work for the first trial. Nothing any issue, however, there is tons room for improvement here.



*5306 can be replaced with MPSA18
*two rectifiers, use 1N5817
*Schottky diode, use 1N4148
*PWR cap, use KEMET MLCC 0.1uF
* .1uF Film can be used to replace the .12uF
* Use 1/8W 3mm resistors

If you guys are interested, please keep follow along.
