|Partial construction of Fifth-Method stabiliser|

A long time ago I started making the "Fifth-Method Stabilised Oscillator" as described by the original Huff Puff man himself, Klaas Spaargaren PA0KSB in RadCom March 1991. My efforts are pictured above (note: board rotated 90 degrees from the orientation shown in the layout diagram below, and digital circuits also added).
I have the circuit diagram of the analogue sample and hold circuit as I built it (click below). I'll probably never finish it, because if I have the time I quite like Peter Lawton G7IXH's Fast stabiliser and will try that instead.
