That's the background story. Anyway, so this weekend I'm picking up some new to me Tannoy speakers. Sensitivity is spec'd at 93 db, 5 db more then my current speakers. I'm hoping this is enough that I can start running my M125's on only 2 output tubes. Once I factor in currency exchange, duty and VAT charges two quads of KT88's really add up. I will have a lot more time for listening (yay), but on the other hand it also means I'll be eating into tube life more quickly (boo) If I can get away with just 2 per amp servicing costs will be much more manageable.
Anyone out there running their M125's on two for perhaps a similar reason? is 93 high enough to expect reasonable results?
