I'm running 7062 in the phase splitter spots on my VTA ST120 amp. These are a little lower in gain then a 12AT7. The sound is great and the amp is dead silent at idle. I can't say if I like the sound better or worse then the mullard 12AT7. This is not a bad thing! Mullards rule so not hearing a downgrade in sound is ideal.
The 7062 is about a half inch taller then the 12AT7 tubes.. The things are industrial and look a bit more robust then a 12AT7. 10,000 hour heater rating. Pretty much bomber. At 15 bucks a pop they work well in the phase splitter
Tube detail -
Philips label Amperex E180CC (7062 / 12AT7 premium tube), military stock
A very nice Amperex made 7062 tube with Philips SQ labels, which is nearly identical with the 12AT7 and 5965 type, which has just a bit lower gain than the 12AT7. These are the low noise audio screened, 10,000hr. rated heater life tubes. Sweet sounding and smooth, add to that the extra quiet and sonic focus of vintage Amperex manufacture, and you may never go back to a 12AT7 once you hear these
