CAUTION - In
the tube section there are projects that require dangerously high voltages.
Exersize extreme care when handling power supplies. Always wait for capacitors
to drain before working on tube equipment that has been operating. Before
working on tube equipment, make sure all caps are drained by shorting them
out with an insulated piece of wire or an insulated tool (screwdriver or
long nose pliers) taking care not to touch anything with your bare skin.
It has been discussed on the rec.antique.radio+phono group that voltage
even as low as 25 volts can do harm. This is confirmed in my little pocket
engineers handbook. Please be careful!
Feel free to
My growing collection
of Antique Radios primarily from the twenties and thirties. Some include
restoration projects and all have pictures.
