The 8.2K resistor drifts too much

[BoogieEngineer]

I got a 8.2K dropper that reads 9.37K, so I had to get another one, planning on using the old on in place of the 10K. But this new one reads 9.41K Thoughts?

I'm not sure why you posted this but...

Maybe your meter isn't very accurate? The slight variation in resistance there will have very little effect on voltages, etc. so I wouldn't worry about it. In case you're talking about CC resistors, it's quite common for those to read higher than marked but I wouldn't use CC's there anyway.

9k4 is fine. try testing the one in old marshalls instead of only following the schematics

Yeah they are both CC's. Why wouldn't you use CC's there? Almost every JTM45/100 build I've seen has got a CC in there. The ones I've got are both 2W if that makes a difference.

Thanks, good to know. What about the 10K near the preamp cap? I guess I could use the 9.3K in place of the 8.2K and the 9.4K in place of the 10K?

They can add noise and drift in resistance. They are historically correct though. (I was just making a general comment about CC's.)

I'm using CC's just for several spots. As for tone, general consensus is that there is no noticeable difference from what I've heard. I find them look cool though

yes, it doesn't matter much though. different tubes will draw different amounts of current, affecting voltages and tone

Thanks Roe. I actually got another 8.2K from Valvestorm which reads 8.4K on my meter, so it goes to the 8.2K position. The 9.4K goes to the 10K place, so I'm all good now
