300ohm trimming resistor

[pjf610]

Hi all, need to know where I can get a 300ohm trimming resistor or possibly a substitute for the p700 main amp board for a 2250b

sm shows wiper and one leg tied together/shorted as commonly done with VR's, so you can use a 500ohm VR, for bias I'd pay the extra buck and get one of those multi-turn blue ones... The multi-turn should provide sufficient resolution to get the bias right.

Thanks, will try to find some
