Here's some more info - A COMPARISON of President Richard Output
The RICHARD uses 2 - IRF520s using a Pull Up "tap" into the 8V TX line
The IRF520's source from the 8VTX thru a 330 ohm resistor, into 1K
- thru the EN1230 style Diode and 820 Ohm Resistor then Grounded
thru a 1.2K Resistor. ....Now onwards...
To President Bill
The BILL uses 1 13N10FQP and directly uses 10K from 8V TX as Source
with 8.2K to Ground.
The above can help those what are trying to make specific conversions work.
One type uses a Hybrid of the EN1230 and the 8VTX voltage thru a Pull Up resistor to accommodate the Gates of the IRF520 Twins used...
The Bill being single-FINAL - uses simple 10K to 8.2K directly across the Gate from the 8V TX.
