Just to be clear, in NO way did I mean to sound negative at all regarding the offerings from Jim McShane. I've bought multiple items from him the past and he's extremely responsive and knowledgeable. I was simply exploring options as $89 for 50 resistors seemed a bit pricey to me.
I also know ZERO regarding tube gear, so I figured I'd ask.
Eli - I don't know about the choke mod. I'll look into it. I was just on Jim's page and wasn't able to find what you're referring to but I'll keep digging. Thank you for the tip!
I paid top dollar for the Citation V because my time is extremely limited right now and I didn't want to have to work on it. In the seller's defense, he did show me the problem with the meter "displaying incorrectly" on one channel once at his home when I was purchasing the amp. He claimed that it'd been that way since he purchased it off eBay. I am simply not comfortable running it as it is because I have no way of knowing how much current the tubes are running at on that channel.
I also have two Citation II's needing rebuild that I was also planning on going through top to bottom. Hence, I thought that I'd see if there was a way to reduce the overall cost a bit. When I start looking at $300 in just resistors between all three from Jim, then add cap kits for the Citation II's at several hundred dollars each, then new tubes for all three, the total cost makes me cringe a bit, as it adds up very quickly.
That having been said, I know this hobby isn't cheap. I was simply trying to see if there was a more economical solution and that started with choosing the best sounding type of resistor for this application.
I'm not new to the DIY audio world and am more than comfortable modding and repairing the amps. I just know next to nothing about tube amps and would rather ask first than make dumb mistakes.
Thanks to each of you for the tips thus far!
Regards,
Steve

5ppm means that the resistor will change its resistance 5 parts per million for every degree C of change in its temperature. So if you have a 1 meg resistor, its R will change by 5 ohms for every degree of temp change. 5ppm is very expensive, with 100ppm, what most metal films do, is common. 100ppm is way better than you need for any tube amp. Use 5ppm, such as Vishay's bulk metal models, only for very accurate instrumentation. It won't hurt at all to use those in a tube amp, but you'll never benefit from them in that application, and they will deplete your wallet in no time.
