Leave tube amps always on?


Mark, the owner of Linear Tube Audio, suggested I leave my tube amps on all the time 24/7 if im listenting every day, and to turn them off if not using for a period of time, a few days or for example we go away.  His reasoning was that it uses considerable more energy to turn on/off on a regular basis. 

Do others agree?  Kinda risky since these NOS Mullard tubes ain't cheap and will soon be gone forever.

i am surprised to hear of the unreliability of the rogue audio unit in your hands

was it an older or well used unit?  did you try to have them fix the problem?

i have had a eye on rogue, as a good, made in usa, brand of tube gear - the brand seems to have quite a few proponents on this and other forums, was perhaps going to try one sometime

now this gives me a little pause
Such a fuss over a simple idea that’s backed by listener experience. Argue if you will about how much is costs to turn-on/off, replace tubes, etc. people who leave their gear on report better sound in the first hour or so. That’s the complete nut.
We’re mostly at home now. Why not leave your system on for a week and see what it sounds like?
Just askin’.


PS Old tube lover now running solid state. I never turn off anything in my system.

As the OP, I started this weekend - turning amp and preamp on Friday after work, leaving on, and will be turning off later today Sunday. During the week, will turn on and off normally.

Its probably in my head, but it sounds better today than the past two days.

The Rogue Model 88 is an older amp. I bought it used. Not long after that, I had a problem and notice the ceramic (?) resistors had cracks in them. Rogue ran me through some checks using a digital ohm meter and at least one was bad. They sent me a bunch of replacement resistors and I soldered them in myself. Pretty easy. I then had a problem with a channel in my Rogue Model 99 pre amp which I sent in for repairs. They only charged $125 which is their bench fee because the parts weren’t expensive. I also had to replace the bridge rectifier in the Model 88 Power Amp at least twice. I did that myself also. Then, I had a problem with the power amp sounding very distorted/scratchy in both channels and would just blow both channel fuses. Sent it in. Rogue replaced some resistors and when I got it back - same thing. I then replaced the entire complement of tubes and still no help so I decided not to spend more money on it and put towards a new tube amp. Shipping the amp wasn’t cheap either. I also have two solid-state amps but I like my tube amp the best.
