here.
There are two 1N4007 silicon diodes in an Octal base.Pin 4 is diode 1
Anode,pin 6 is diode 2 Anode and the two cathodes connect to pin 8.You
will probably have to include a power resistor of about 47 Ohms @ 10
Watts to drop the output voltage to the same value as would have been
provided by the vacuum tube rectifier.
