How should you treat your tubes?
EL-34's are used as output tubes in guitar amps and tube amps, and are also commonly used in tube power supplies. As I noted above, tube amps should not be left powered up, if only because output tube failures can be speactacular (I've made a mad ... 
How should you treat your tubes?
A final point: if you search the threads, you'll see that this subject has truly been beaten to death, as well as the more general subject of whether to turn equipment on and off or leave it on 24/7. In those threads, you'll see that repair techs ... 
How should you treat your tubes?
I had a thorough response written and I lost my Internet connection and my text.Larryi: The VAC 140's have no means of powering up only the 6SN7's. The amp is either on or off, and I turn it off and on as needed. The 6SN7's are not a worry, howeve... 
How should you treat your tubes?
Small signal tubes such as 12AX7's or 6922's are generally best left on 24/7. Quoting from the "TIPS & ADVICE" section of the owner's manual to my VAC Rennaisance 140/140 Mk. III tube amps:"How long should tubes last? It has long been known in...

Imin2u: I can explain it. Tube gear using small signal tubes such as 12AX7's or 6922's is generally best left on 24/7. Quoting from the "TIPS & ADVICE" section of the owner's manual to my VAC Rennaisance 140/140 Mk. III tube amps:"How long sho... 
Accuphase dp90 dc91 are they still good?
It is generally best to avoid old digital. CD players are computers and their performance will be overtaken by newer CD players as the relevant technologies progress. I have a 1994-vintage Cal Audio Labs tubed DAC up in the closet that is quite en...

You have to decide whether you believe that the mono or stereo releases best captured the intention of the group and Martin in the studio.As for sound quality, the early 80's Mobile Fidelity Sound Labs LP box set is arguably the best (they are ste... 
Leaving DAC on all the time OK?
Larryi: It is precisely because most modern tube preamps use solid state rectification that powering them up and down kills tubes. I agree that a soft-start circuit (CAT preamps come to mind) or using a thermistor will do a lot to ameliorate the p... 
Leaving DAC on all the time OK?
Techs will tell you to leave all equipment powered up 24/7 except for tube amps (output tubes tend to pass a lot of current and have to be turned off to prevent excessive tube wear) and Class-A biased transistor amps (which burn too much electrici... 
6550 and KT88 differences?
With respect to its design, the KT-88 is the British variant of the 6550. In use, they have proven less reliable than the 6550, particularly back in the 80's when their were some especially poor quality Chinese KT-88's that were more roman candle ...

Audiophile TT article in Forbes
If you google "Forbes" and "Fremer" and "VPI" and "vinyl", the link to the article comes up first (moderators often don't like links, which may be why no post has mentioned the link, so I'll try it this way). I prefer to focus on the article, whic...

The best mini monitors you have heard?
I agree with the above poster about the Dynaudio C1 -- a very good monitor (clearly better than the very good Special 25).But Audiomachina's (Dr. Karl Schuemann's) Ultimate Monitors, which I just purchased and have been listening to over the last ...
