As I've stated above, I am a fan of low-powered tube amps. I own a pushpull 45 amp, a pushpull 349 amp and a parallel single-ended 2a3 amp. I like the sound of all of them. If forced to pick a favorite, it would be the pushpull 349 amp (5.5 watt), followed by the parallel single-ended 2a3 (6.5 watts). The very best amps I've heard were both very exotic--one is a custom-made output transformerless amp and the other is a pushpull 252 amp (a tube similar to a 300b, but much rarer). In other words, I would not say that any particular topology is superior to another--there are good examples of each tube amp type.
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
