Re-installing a brass nut on my LP Studio.

[Simon Barden]

I really don't like no-name Chinese valves. I've never heard a good one yet. Several of them I've had you could hear them physically rattle. The one that came in a Fender Champ 600 was probably the worst as you could hear it over the amp! At least ones with a known brand name on them will have been properly quality checked and be of a higher quality to start with.

One of these days I'm going to have to invest in a good valve testing rig, and learn how to sort through all the good ones from the bad ones, I'm going to be ordering a set of three new 12AX7 valves from Evatco soon, the ones in my Marshall are just to keep it useable till the new ones arrive in the post, I was thinking of ordering either a set of three Sovtek 12AX7 LPS valves, or a set of Electro Harmonix 12AX7EH valves, or maybe some JJs, I want to get ones that are high gain but low-microphonic and low noise, so maybe ones with small anodes might be good since they tend to be low-microphonic, might even end up ordering three Sovtek 12AX7WA valves.
