Need part value GR 1340 Pulse Generator - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

I have a wonderful GR 1340 pulse generator. There is one burned out resistor. I would truly love to repair this generator. A schematic would be great. However, I may be able to fix it without a schematic. If you have a GR1340 you might be able to determine the part value for me.

When manufactured, one resistor lead was not trimmed against the PCB. So here it is decades later, the resistor lead finally shorted against the chassis. The generator still generates 50% duty cycle great, but the variable duty cycle no longer works.

If you can help, I would very much appreciate it.
