Phono Preamp

Oh, and the transistor, invented in 1948, so that’s nearly 72 years old. Not so far from the “100 year old technology”. What the age of the tech has to do with anything I don’t know. Hmm, now that I think of it all of my gear has ancient transformers in it! Those transformers predate the tubes and the transistors, guess I have to get rid of all my tube and solid state gear. 
Again smh, some of the reasons I read on this site; in the words of Kelly Bundy, “the mind boggles”.

Comparing transmitter tubes to small signal tubes in consumer gear. Literally shook my head. 

I have one class A amplifier, the Reimyo PAT 777, three Graaf OTL’s, a set of switching amps with linear supplies (one of the top three Solid State amps I’ve every heard) and various other amps. I’m not married to one technology. 
I can easily find matched tubes, the Pvane Black Treasure MKII’s are exceptional and can easily be matched at Parts Connexxion. They have bettered all NOS 12ax7’s and 12au7’s I’ve tried.

David Bernings gear is also exceptional and the tubes last a very long time. Just so you know transistors do go out of spec. They are not magic, they can drift and often do.

Again, I listen to tubes and SS but when it comes to my Phono Stages, I’ve never heard a SS unit regardless of cost and that includes the CH Precision P1 that can outperform my Lux Eq500 or my AMR PH77 BUT, that’s to MY ears and I’m in no way making an objective finding that tubes objectively beat SS. 
Tubes have there issues, but so do most high-performing items.
