Hi Guys,
I have moved to Canada and am rebuilding my amp as the iron was just too heavy to haul in the cabin. Having added a few years poking about with SMPSs at work in the meantime, I am going to SMPS power this - which leads me to the questions below...
I have the following choices (to drive Brimar 6V6Gs)
Brimar 12SN7GT
Used this before, it works. Sounds great from what I remember in 2009.
Mullard ECC33
Not tried this before, but they sell for $250-300 on Tubeworld...what is going on?! I know the transconductance is higher, but otherwise it's 'close enough' to an a 12SN7. My primary reasoning for using this would be that I'd only need one heater downconverter... I must have a gander at the curves (The ECC33 is a 'switcher' type tube?)
