Hi Bill:
Install a pair of 1N459A diodes, one reversed back to back to ground. They
will sync everything and short if hit hard enough. Kindest regards Jim

In the process of restoring a NC-303 receiver, I noticed that the 33 ohm
resistor at the control grid of the RF amp tube (6BZ6) ?had fried in half.
All other resistors in the circuit are OK. It's no problem to replace the
resistor but I could use some advice as to why it happened in the first
place and is there more to it than I know. Any help appreciated. 73, Bill,
