Transistor bank

The HRSA offers a transistor bank service for a limited number of older transistors – both germainium and silicon.

We make no guarantee that the transistor or an equivalent will be available. 

You can also try the following:

Asking fellow collectors, either at meetings or by putting a request on an internet news group can work if it is something not stocked by the HRSA or electronics suppliers.

Members can use the yellow pages section of the HRSA Radio Waves magazine to advertise sales and wants.

See the HRSA Links page on this site for some component sources.

We also sell manuals and circuit books, and things like ferritte rods, and kits.

Contact Peter Schwelger to confirm availablity and to order.
