You can find radios to salvage at thrift stores.
#Transistor radios at radio shack full
The two sections only add up to 220.ones used in the plans are 365pf but you can add a fixed capacitor to switch in to get the full range. Most AM radios have 60pf/160pf varicaps in them. You can use the varicap from the radio too.just add the two sections together. if you want to really get fancy or even wind a loopstick form from kraft paper and glue with a nut in the end and wind your own coil on it. You can engineer some type of threaded rod tuning mech. Unwind a few turns and add a tap if necessary. If you need a substitute for a loopstick for the radio projects, you can use the ferrite rod and coil from a AM radio, just slide the rod in and out of the coil to tune. Check out the cool little HV supply it uses and how it uses the neon bulbs as reflex oscillator. Neon Goofy lights is another one of my favorites. Of particular interest is the simple WWV time signal receiver and three transistor shortwave.
The projects all work quite well for as simple as they are. Look for long silver cans with 2SB and a lower number.
You can also get these from old RS 100-1 kits, and many old transistor radios will have Ge transistors in them. First come, first serve, as I only have just a few extra. I have a very small supply of these available if you are dying to build one of the projects then send me a pm and you can have for postage. Only problem is many of the designs use 2SB54 Germanium transistors.
This website has schematics and instructions for most of the old P-Box Radio Shack kits available.Īhh.back in the day when Radio Shack sold the good stuff.
