Sophia Electric's 845M vs. SuperTNT 845M ?

Sophia sells the current production of the older Shuguang 845C, but it's a better tube than the original 845C in my experience. I'm using the Sophia-sourced tubes now and think enough of them to have a back-up pair ready in case disaster strikes :-)

Dopogue: What other 845s have you used before the Sophias? How do you like that 845C over the others?

I'm having a pair of Cary CAD211AE now..do you know what dissipation ratings Cary run on their 211AE?

Can't help you with the dissipation ratings, sorry. I've tried various 845s, starting with the cheapest Chinese ones, then the 845Bs from Super TNT and elsewhere, and ultimately the ones from Sophia, These took my amps to a new level of clarity and dynamics, quite a marked improvement over the "B's". One of my first Sophias went bad after a litle more than a year, but I've had no further problems. The current pair has been in place for around 8 months IIRC. Dave

thanks guys.
Coolhand: You are right. Sophia's metal plate 845s are improved version (or better QC) of the 845C. I emailed SuperTNT and they said the latest SuperTNT 845M will be available again in Dec this year....hopefully that will happen !
