General Information and Shipping

For those who like to design and make there own Crystal Radio set we sell the parts (1N34A Diode, Ceramic Earphone). The 1N34A Diode is the diode of choice for crystal radio sets. The 1N34A, 1N60, 1N270, are germanium point contact diodes. Also the MK484 complete AM radio IC that looks like a transistor.

Crystal radio sets are a great way to introduce young people to electronics. Crystal Radio Set kits are easy to make and Crystal Radios do use external power sources other than an antenna and ground. The principles of a Crystal Radio Sets operation are not hard to understand.

A Crystal Radio set requires a good antenna and ground for the crystal radio set operate properly. This is because the Crystal radio set needs about .2 volts to be generated in the Crystal radio set tank circuit. Our simple Crystal Radio Set Kit is great for children of about 13 years old to learn Crystal Radio set making and how a Crystal Radio Set works. I say 13 years old because our Crystal Radio Set Parts Kit requires some soldering. 

Some of the crystal radio set kit parts are no longer sold or made in the USA any more. Crystal radio set parts are becoming harder to find. You can find however most of the hard to find Crystal radio set supplies here.

We sell transistors MPF102 JFET , J309 FET, 2N2222A , 2N2222, PN2222A , 2N3904 , 2N4401 , BF981 , MFE201 , 2N3819, 2N3906 , 2N4403 , PN2907A .

Some of these transistors are becoming obsolete like the 2N2222A , 2N2222 , . The 2N2222A or the 2N2222 transistor in my opinion is almost a universal transistor good up to at least 300 Mhz.

The PN2222A transistor is about the same as the 2N2222A or 2N2222 except it has a lower power rating.

The MPF102 JFET is a VHF hi impedance device. The MPF 102 JFET can be used from audio to about 400 Mhz.

The 2N3819 JFET is another hi impedance device like the MPF102 the 2N3819 is also good from audio to VHF/UHF .

The J309 FET is another hi impedance device good form audio to VHF/UHF only manufactured to tighter tolerances than the 2N3819 and MPF102
