Tube Amps

Tube amps are really not that hard to use or maintain, but there is somewhat more effort involved than with SS. For your first amp I would recommend that you get one that is fairly idiot proof but that allows you to maintain your self. Individual bias pots and built in meter is fundamental to ease of use and tube rolling. Make sure that you can easily find good replacement tubes at fair prices. Make sure that you can easily bias the power tubes yourself. Its nice if the unit has a fuse to protect the bias resistors if a power tube shorts out - saves a trip to the service tech (this doesn't happen often, especially if you buy tubes that are known for being rugged in the first place, and avoid tubes which are not. (I just bought an integrated unit with both a fuse and auto bias, talk about idiot proof). You must also adopt the attitude the tube changes WILL BE necessary and its not a big deal, just keep extra tubes on hand so when one fails prematurely you can just replace it, and keep a set of both small tubes and power tubes on hand so you can replace them when they ware out. No different than doing maintanence on your car. Then sit back and enjoy. If you provide some detail about your speakers, room size, and listening preferences you might get some meaningful reccomendations.

As others comment, allowing for for easy bias adjustment with a built in meter is a good feature. But note that (1) some tube amps use LEDs that go dark when the amp is correctly adjusted (easy to do) rather than a meter (e.g., the Conrad-Johnson MV-60) and (2) some tube amps are automatically self-biasing with internal sensing circuitry so the user doesn't have to do any bias adjustments at all (e.g., the BAT VK-55).

appreciate your insites and input...
the price range of $1500-2000 would be for either used or new
currently i run a mac mc252 on a set of ushers x719 which are 8ohm and 88db. the room size is 12x12...
i am fascinated by looks mostly and cool factor...is that worth the maintainace and biasing issues...btw what is bias tuning? is that a gain adjustment and is it a L/R or something else..
my other fascination is with class A rated output amps...are they worth it?
sorry i am a novice but got a serious bug..
thanks

I guess one would have to have one of these tube amps in their own system before one could judge.----There is one thing I can tell you ; they (tubes)do sound pretty different than most solid state amps--A generalization only--- Whether or not you like that difference is another thing. I say listen to a triode amp, not necessarly a single ended one but a push-pull triode. Then you can tell us.--- Some tube amps have a simiar to SS sound; and some SS amps have a similar to tubes sound.---Don't know of many SS amps that have a similar to triode sound; there may be some but the price won't be in the 1--1.5k range.

The previous post by AVguy makes a good point: moderately priced tube amps can, and usually do, sound quite different than comparably priced solid state amps (due mainly to the much higher cost for transformers in the tube amps). The performance difference between tube and solid state amps have been narrowing over the past 10 years, but that's mainly true for the higher-priced models.

If you want to experiment with a tube amp, you might look for a used Quicksilver amp, which is user-friendly and offers good performance for the money. You might also consider some of the very good tube amps now being made in Asia (mainly China and Taiwan), which offer good value due to their lower manufacturing costs.
