Never Owned a Tube Amp and Want Advice


Hi All, 

I have never owned a tube amplifier before and am planning to purchase one with a minimum of 50 watts per channel to mate with 8 ohm 88 dbl speakers.

My hope is experienced audiogoners will share their expertise regarding how to approach this. While I realize listening is the best way to learn about sound and compatibility; I want to learn a better understanding about brands with less maintenance and longer tube life, how to decide between mono or stereo,can a newbie play with bias or is auto biasing a better first choice, etc.

I would also appreciate what to look for in selecting a used tube amp to identify one that might be in need of repair. For example, with solid state depending on the brand, capacitor replacement can be more of a concern. Any advice on what to look out for or ask about with used tube amps would be appreciated.

A big question I have is how to understand the relationship between power tubes like E34's, 120.s, etc. and, I guess the driver? tubes like 12au7's and 12at7's. That  is to ask which is more critical to the overall sound of the amp? FWIW, I routinely tube roll with my preamps.  

I 've read through a number of threads but maybe someone can point me to good ones I may have missed. 

Thanks for listening,

Dsper

I rarely if ever disagree with Ralph and find his amps among the best I have ever heard. It was millercarbon that made the statement which I questioned. BTW this isnt the first time miller has made this statement about tubed vs S.S. watts.
Here we go again with the statement that tube watts are greater than S.S. watts. This statement is patently false and should call into question anything this member says in the future. Also, I maintain that impedance is more important in the greater scheme of things than efficiency when considering speakers with tube amps. Higher impedance speakers allow one to consider OTL amps which are the best I have heard.
