Last night I put a headphone on the amp and fed it with a antenna through a diode I received signals. Without the diode all is quite. For t...

Joe had a dead battery and Tom offered to help. When they connected the jumper cable one had a bad end and it fell off. Joe says "Oh m...

The as built schematic except one resistor. I put a 470 Ohm resistor in series with the diode to avoid inrush on power up. I ran the ...

DIT produced a winner with the Cap Divider. I put it on a breadboard and the results were impressive. The datasheet offered this circui...

I took 6 .5ufd caps in parallel to replace the 5ufd cap and bingo! 12.56 volts feeding the heater. The tube has a nice warm cherry glow. ...

The DIT did good with the capacitive  divider. It had over 400 views and counting. I pieced together a little board with one powering a t...

It is not pretty but it sings. I put a drop of glue where the part was located on the schematic and attached the parts. Then it was just ...
