Are you working off of the paperwork for the 604C or 37-604C? I see yours is the later version. I looked at Nostalgia Air for the paperwork for the 37-, but it wasn't listed. I know there were changes between the 2 models, most notably, the tubes used.
I would think any changes would be documented in Philco Service Bulletins, but I couldn't find any around the web for that model. Hopefully someone here will have access to one.
That said, part number 33-3010 is rated at 300ohms, so if it measures 329, it is within 20% of rated value. I'd leave it alone.
