Can anyone one point me in the direction of some good super regen. schematics, i'm waitning for some parts on another project. I found some parts in my junk box that would make a good super regen. but i don't have a good schematic, The bigest problem is they don't give the turns fot the coils. I have an old cathedral that has nothing other than a chasis with shorted IF and RF transformers and the oscillator was totaly destroyed. It has a couple of 57's, a 58, 80, and a 47. the powere Xformer is good:). I cant find the radio, it is a silver marshall, so i think i'll see if i can utilize what's there and make it work. Any i deas other than mine are greatly appriciated.

Lindsay Books has lots of good books on the subject.

Hmmmmmm….When you put down those magic words of….. Superregenerative…….. I would be at a loss to not recommend a circuit that I ran across back in the ‘50’s.
It is truly a “bulletproof”, trouble free circuit, no spurious oscillations or touchy adjustments. To get the coil for the lower freqs, I used a 365 var cond meshed for max cap and then peeled off turns of Litz wire from an IF coil until my lowest (540kc) signal came in and then cut out the loose wire and reconnected. The higher freqs then just fell in as the cap was opened and decreased in value.
I built it as shown and then later merely used a triode tube (12AT7)when shifting up its operating freq to the business band, FM Band, hi way patrol, police freqs, ham bands, or basically, just anything that a one coil tank and variable cap tuning it would resonate to. If using an audio amp after the circuit, vice the phone shown, merely sub in a load resistor instead, and then capacitively couple on to the AF amp circuitry following. To really hop it up an RF stage can be put in front and loosely RF coupled into the unit also.
