Tube Watts Vs. Soild-State Watts?


I am considering replacing a large solid-state amplifier with a decent sized tube amp, and was wondering what I may be giving up/gaining by making the change? My speakers are quite sensitive, about 98dB. I love the dynamics and bass control the big SS amp provides, but I would like to get more resolution and detail out of my music. I don't play music at loud volumes, but I do enjoy decent listening levels. Any info appreciated.

Jeffery,
Your description reminds me of a NAT audio (Serbia) type SET amplifier. If at all similar then it will have terrific quality output transformers and very robust power supply. They are very ruggedly built.

Still Triode SE, So are a host of others used in audio in set amps, just to name a few from memory 211,845,805,GM70,VT4C, ect ect

" The tube amp that I am looking at is about 80wpc single-ended class A. My current amp is solid-state 400wpc class AB. My speakers are Tekton Design Double Impacts. My previous experience with tube amps was mixed, as the amps had some characteristics I liked, but were not very dynamic. I like the sound of my solid-state amp, but am wondering if I could get more detail out of my music by going to a tube amp."

Try to find an ARC VT100, or a pair Quicksilver V4 mono's. That should take care of the weak dynamics.

Your not going to find a one tube single ended triode at 80w unless you get one that uses the 833 tube.
Or it’s going to have to be a paralleled tube set using a pair of these tubes 211,845,805,GM70,VT4C

These 2 x GM70’s in set will give you 45w.

A paralleled pair 13E1 in set will get to 70w

I seriously doubt if the referenced single tube "transmitter" tube was designed for wideband audio reproduction. Sounds (no pun intended) like a component used for (tele)communication applications. Curios to hear more about it.
