Tube reliability in amps

I have had great success with the Music Reference RM 9 MK II
amplifier. I have had EL34's in there for years already, and I still have no problems with noise or sonics. This amp
creates a good argument for tube reliablity.

I've been very happy with CJ tube amps for reliabilty, sound, and ease of tube replacement and rebiasing. I'm running the CJ Premier 11a as it does a fine job with my Thiel CS 1.5's. I'm not familiar with your B&W's and if they are in fact "difficult to drive" then you might want more power and that usually equates to higher cost. (not talking about low power SET amps here as they do not apply in this situation).

Ive been using a pair of VTL monos that have easily adjustable bias (about 30 min 2x per year and it could be done a lot quicker but i'm kind of a-r about it). Warm-up time is usually about 30-45 minutes before they start sounding real good, they keep getting better for the next hour or so...they sound somewhat dry and one dimensional at first...kind of like solid state. I bought them 6 mo old about 2.5 yrs ago and am still on the original tubes excepting 2 a near hit lightning strike claimed. They will probably need to be changed out by summer end (getting a tad soft but still sound good). I also use tube guitar amps exclusively and they live a MUCH harder life than any audio rig...no problems there so far either. try the tubes you won't be sorry

Drjjpdc, I like Jena would recomend the Music Reference RM9 as a very user friendly, musical, and indestructible power amp. This amp can use (8) EL34's (very inexpensive) which are very musical, or 6550c's (a little more expensive not necassarily better) with a little more authority or KT88's (much more expensive than the EL34's) that some people love. It is rated at 100 watts per channel with the EL34's and probably more with either the 6550 or KT88 tubes. Is very easy on tubes, probably well over the 2000 hours that seems to be the norm. Very easy to bias (won't need any meters, uses LED's), right from the top of the amp, and is a very pretty amp INHO. Usually you can find these amps for around $1200.00, they came in two versions RM9 and RM9 MKII. I personally favored the origianal. I have owned 2 and will surly own one again. Good luck with you search.....Bob

Might add the Music Reference RM-200 to this list.Lots of bass for a tube amp and absolutly beauitiful to look at.All Music Reference products designed for long tube like.
