    7062 / 12AT7

    Post by mantha3 on Tue Jun 21, 2011 7:49 pm

    Yo!

    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

    Interesting. Where did you buy them?

    Thanks.

    Brent Jesse is pretty cool too. These tubes I got are the cheaper (maybe the cheapest 7062s he has but they work great for 15 bucks a pop.

    You can Def. get better/more expensive 7062s if you want.

    PS - I'm not sure if the filiment is going to draw more... So classic ST70 owners may want to check. the filiment looks a little beefier then a 12AT7

    I've never tried the 7062, but I checked the data sheet, it uses 200ma of 12.6v for filaments instead of the usual 150ma, not too much more

    Hmm,

    I'll have to check my tube box. That's good info.

    I got a sleeve (5) of Sylvania 12AT7's that just sound sweet to me, don't ask why. And when I had a hum problem, they were the quietest of the bunch. I think I got lucky there.

    I need to do some tube rolling, and maybe I need the 7062 in the mix.

    I gotta get a dedicated CD player on the ST70. Maybe I'll try my Mitsubishi DVD player in there. I need to see if it has adjutable output via remote, that would be too cool. I know my Adcom does (and I was kinda looking for a single disc one of those cheap just for that purpose).

    Did you try 3 of them?

    I didn't try 3 of em. I only picked up 2. I tried one in the center spot with some Mullards in the phase splitter spots... Sounded solid. I then put these in the phase splitter spots and I'm running a NOS Siemens 12AT7 in the center. The Siemens 12AT7 is probably my best 12AT7.
