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

I spoke to them about this, their metal plate 845 are actually 845C, which is not the same as the Super TnT 845M, the C has lower dissipation, which may or may not be suitable for your amp/s...check your amp manufacturers specs.
Apparently Super TnT "may" have more 845M before the end of the year....

Regards,

Thanks man...the 845C is the older model then...i heard the newer SuperTNT 845M has higher dissipation rating...and can be used in any 845 based amps...but they are out of stock now i think :(

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 :-)
