Which tube will give me the lowest noise / hise in my speakers?
I bought the BHK 250 + pre used so I don’t know how much noise the combo has from new.
Currently I am using a NOS One Electron JRC 12AU7 from august 1953.
The noise is tolerable but I would really like to lower it as I can hear it from my listening position.
One thing I have found out is that if I use RCA cables I get a lot of hum and noise, like it is broken.
So maybe some of the noise I am hearing is some kind of ground issue.
Because RCA is a no go.
Personally I’d give Brent Jesse a call, and see what he has in stock. He is a solid provider of tubes in general and should be of great assistance. You are going to want tubes that are actually available, which is why I’d recommend a solid straight shooting provider.
