Go to Post The very fact that parts are rumored to be being re-used may be sufficient reason for the rule-makers to change a rule to prevent the re-use of that very part (not that they would ever be that devious!) - dlavery [more]

Re: Victor 884 Schematic Diagram

It turns out the 10K pull-up resistor on the output of the NPN transistor limits the current below what the speed controller requires.

The solution was very simple. Changed the 10k value at R1 to 1.2k and now the circuit drives either a Victor or a Jaguar just fine.

Thank you for all your comments and help.

- Hugh
