Want mine instead? I think it's a 40's model, though, so it's relatively new.
I still have two from the 50's and a spankn' new one from the 70's
My 40's model works perfectly. I've been worrying about the tubes but so far no problems.
Tubes are not as hard as you think unless you get into ones used in amps then they get a bit pricey
I've never been a great believer in tube amps. I know some people prefer that sound, but I'm a bit more pragmatic.
There is more difference between "Single Ended" type amplifiers and "Push-Pull" type amplifiers than whether or not to use tubes or transistors. If your listening equipment, as a whole, is capable of high enough resolution to make the slightest crossover distortion audible, then Single Ended Triode amplifiers are the only way to go.There are some Class A Solid State amps that approach zero crossover distortion, but they are extremely pricey.
A good SET tube amp is free from this kind of error, but what you give up is power. So, the pursuit of very efficient speakers becomes another issue.
You might be really surprised how seldom I turn up my two watt per channel amps, during a close listening session.
When I want to shake the floor and dance around madly, I use a big sand box, though.
