Mismatched power tubes in Stereomour 45 -

[B00B00]

Hello all... I am the new happy owner of a lovely Stereomour 45 with upgraded caps. Sadly, I did not build it.
It is everything I thought it was and probably more as I'm still getting to know it. It did come with two different power tubes.
A Tung Sol Made in the USA with silver frosting on the backside and 45 written on it and an RCA Cunningham with silver frosting.
I understand the amp is self-biasing. It sounds fantastic with this combo. Any danger because of the mismatch?


Thank you,

Despite what's written on those tubes, do they look the same on the inside?  Are the top mica wafers the same?  They may actually be the same tube made in the same factory, just with different branding printed/etched on them. 

Even if the tubes are quite different, there's no harm done by this in the Stereomour.

Thanks Paul, very much appreciated.
