A sad tale of tube problems...


Before I tried tubes, I was warned that they are a pain, can be expensive, can fail, will develop hum issues, etc. Well, I had no idea how bad it was going to be. I have tried repeatedly over the past couple of years to get some tubes into my system, and everything has failed. If only they didn't sound so good I would just commit to solid state. Here's my tale of woe...

1. As my welcome back to the audiophile world, I bought a hybrid integrated - got a terrible buzz through the right channel. When I turned the balance to the left, the buzz through the right channel got louder. Never got it solved and went to a SS integrated.

2. Got into vinyl and thought a tubed phono amp would be great. The first one lasted 5 minutes and the right channel dropped out completely. Replaced the tubes, still no luck. They sent me a new one, but I was getting significant distortion. Turns out even the lowest gain setting was too high for my integrated amp. Went to a SS phono amp.

3. Tried a single ended tube integrated. Had a hum problem that was audible from 30+ feet away. Shipped it back for repairs. Came back to me and broke down within the week. They sent me a new one - hum was still there although not quite as bad as the first unit. Went back to my SS integrated.

4. Tried another hybrid integrated. Lasted a week before a loud pop caused horrible distortion. Had to send it in for service. Went back to my SS integrated.

5. Bought a SS power amp (worked great) and used my integrated's preout. Then decided to try a tube preamp. Got significant bleed through on one channel, and when the volume was off I was still getting sound through the left channel. Went back to using my integrated as a preamp.

6. Gave one more shot at a tubed preamp. There was some tube rush through the right channel, so I bought upgraded tubes. Put them in and got a terrible hum through the other channel that I couldn't get rid of.

Counting the replacement components, that's 8 tubed products - and not one has worked. I guess I'm doomed to solid state...:(

Just had to vent...

p.s. I have tried with and without power conditioners and an Emotiva power strip to stop DC on the line. Didn't make a difference.

Bummer, Smrex. I've used a push-pull integrated for six years without one single hiccup. I Replace the power tubes every two years or so ($80) but expect the small ones to go a decade.
how about finding a dealer who carries, and has lots of experience with, tube equipment, then taking components home for try-outs before buying? a good dealer will do this, and it would've saved you all the above problems.
I've personally used tubes for 20+ years (dynaco, audible illusions, CAT, Cary) with almost no problems. in fact, in some ways, tubes make problem-solving easy, since most issues are just a bad tube, easily diagnosed by switching out tubes. sorry to hear your tale of misery though!
"For the most part the components were very well respected brands - some new, some used. In any event, I just needed to vent a bit. To me, tubes sound so much better than SS that I will keep chasing the dream :)"

There's no reason why you can't have your dream, instead of chasing it. You just need to alter your approach. If you choose to share some more detailed info, I'm sure we can you make better choices.
Now I know why I have had such good luck with tubes...You've been getting all the faulty tube gear.
Thanks!!
(Just joking, that's a lot of problems)
Hi Scott,
I'm sorry that you've had such failure and frustration with tube components. It's as if my experiences with tube electronics has been the polar opposite of yours (for whatever reason). A former push pull amplifier would occasionally blow a resistor due to a bad output tube (6550/KT88). Another PP amplifier (el34) is still performing flawlessly in a secondary system in my out of town apartment, this amp I've owned for 20 years.

My main amplifier is a 300b SET and is unquestionably the best sounding I've ever owned (tube or transistor). This SET has a very simple circuit with a low parts count. It is utterly reliable and has required hardly any maintenance at all. I agree with you in that I do find tube amplifiers better sounding if they're well implemented/designed. Scott you situation is an unusual string of bad luck it seems.
Charles,
