    Sounds like (excuse the pun) the design was a bit compromised in ratings, or near max dissipations.
    I like to de-rate as much as possible so as to keep temperatures low and ensure very long lifetimes.

    Yep, exactly the same as Prima Luna do.

It had a recurring habit of valve regulator failure and corresponding failure of its valve, must have replaced all 12 of them eventually, then the mains transformer went up in smoke, literally!
    Got a replacement transformer then sold it on, was glad to see the back of it, sounded lovely when it was working, had real synergy with my ESL63s.

    That was not typical of valve gear even back before that. One example, AKAI reel to reel tape recorders started out with valve amps in them. I have seen 4 examples in recent years that turn on a still work perfectly. The seldom needed any servicing in the day (except for mechanical things). Nice sounding little valve amps btw.

    I have played valve guitar amps all my life, and gear like that gets totally thrashed. Loaded up in trucks and carted around, and played at 110% on stage. Other than replacing output valves occasionally, or a fuse, I can remember having to do an actual repair maybe three times in 40 years on either my amp, or other band members amps. Once the bias resistors on the output cooked, and once, and resistor in the power supply went o/c. One other time on an amp from the 1950s an electro cap spat is guts messy but easy to fix.

    No valves are not as reliable as SS, but they aren't all that bad either. A well designed hifi amp should be good for the lifetime of the valves (which is longer than many believe) a few times over.

    Possibly not as reliable as solid state amps but then solid state amps are not going to compete on sound quality.

    Bit early in the morning to be cracking open a can of worms isn't it? Still, I suppose it is the holidays, might even join you.

    Slippery slope all this valve stuff Iíve had loads and itís all down to personnel prefence and of course symmetry , If you donít want to change your speakers then perhaps go the valve pre route to start with.
    I have a pair of Audio Note AZ2 floor standers here and a pair of Audio note Zero power amps that you are welcome to have a listen to as we live in the same county , the speakers are excellent sounding and built for valves but the Amps wonít drive your speakers

    Have you looked at the World Design web page ? (http://www.world-designs.co.uk/products.htm).. The KEL84 is regarded as a 'giant-killer' and can be purchased in kit form or already made.

    (I have just built the KEL84XL kit).
