Glenn's 300 perhaps?????
Nice tubes George, Good Luck.
Pretty good actually. Very detailed and quite neutral. I'm a bit annoyed that the tubes are of different construction though; one has straight slots instead of round holes on the plates, and is shorter than the other. I'm currently speaking to the seller to see if I can get a pair with same construction.
I am pretty sure these were not manufactured by GEC... Does anyone know who made them?
Edit: Oh, I meant to post this in the 6AS7 thread... sorry..... :(
Does anyone have any idea who made these?
PAIR IEC MULLARD ECC 6SN7GT METAL BASE VERY RARE TESTED GOOD
These don't look like anything I have ever seen before.....
I am fairly sure MOV is correct for the maker also could be labelled Marconi, Osram, GEC, MWT, Pretty much at the top of my 6SN7GT list though bass heads might prefer other tubes. Many labelled as CV1988s for the military but also often seen as B65s.
