Is a triode the best tube to use for a regenrx?
Is COPPER TAPE good to use for a variable inductor?
is DENCO "dust iron core" the same as ferrite rod?
Is it a standard to leave the 6V heater out of tube radio schematics?
is it OK to use NIXIE tube power supplies for B+
is it OK to use two 12 volt transformers to make 170 volts
Is NICKEL good to use for a variable inductor?
Is the number of tuns including all the coil or just some of it?
Is the transformer required to drive the piezo element?
Is there a way for one to receive DRM, HD, and/or DVB with any software?
IS there any reason to NOT use steel studs for radio chassis or face plate
IS this a choke and a transformer or is this one transformer made of 3 coils
Is this a regen?
Is your regen a "Blooper"
