In Reply to: My tubes are down and I'm running a sand amp....... posted by Chris Garrett on August 27, 2002 at 11:42:38:
....there is a WHOLE LOT MORE sand, in a tube amp, than there is in any SS amp. In fact, there's more sand in ONE 12AU7, than a couple of dozen big output transistors.It is therefore appropriate to refer to tube amps, as 'sand' amps.

Trev,I've never had a tube 'blow', or a PS or output tranny burn out, and a while back I bought a Fisher receiver from one of my brother's elderly neighbours where it had been used every day for 40 years, often being left on all the time. It still had all the original tubes. The lady I bought it from had a file with all the receipts of all the things she has ever bought or serviced. There were none for the Fisher, except the sales receipt. It had 2 faults: a hum, due to old PSU caps and resisitors, and a couple of scratchy pots.
I've had far more trouble with Naim and Perreaux amps ( to name 2) than I've had with 20 years of tubes.

In the glass envelopes maybe, but not in the signal path.
Go get 'em Trevor : )Between Chris' post and Ozzy's response, it sure sounds like SS is a WHOLE lot more reliable, doesn't it ? No costly vintage tubes popping, no transformers going up in smoke, you don't have to worry about leaving your amp / preamp on all the time, etc... Sean

So much for my Cary lust . . .
They are just a different "animal" than SS and should be treated as such. One of the systems that i have uses a tubed preamp, tubed power amp, tubed DAC, etc... I've not found a tubed tuner that i want as of yet, otherwise that would be in there too : )Keep in mind that the tubed preamp is 30+ years old and the power amp is now 41 years old. As such, they've obviously proven that tubes and tube circuitry can last a long, long time and still sound good. Sean

a Pass Aleph 30 gobbling up 250 watts continuously and acting like a barbey-q. But, God help me, I love it.
but almost all high bias SS amps sound best when left on. This is not to mention the phenomenal amount of in-rush current that you avoid time and time again by leaving it on. Sean
