More D'Yquem Problems

My issues with Shindo D'Yquem amps continue. Tonight I attempted to turn my amp on and within 30-40 seconds it just died. No power at all. I have had many tube failures over the course of my ownership of these great sounding amp's but now am pretty much fed up.

It seems about every dozen or so times I go to power these up something bad happens. So far bad tubes have been the supposed cause of the amp failures. This time it appears to be the fuse as the tubes seemed ok upon power up.

After a record amount of Gold Lion 300b tube failures and now what appears to be a fuse issue I would have to think maybe this amp design is flawed. I have not heard of many tube issues with other Shindo amps so the D'Yquem may be unique in it's unreliability.

As much as I love the Shindo sound the frustration and anger with these amp's have created a situation where the tolerance of not knowing if your gear will work now far outweighs the sound quality.

Change is in my future.
 
I'm so sorry to hear that. However one of MC275 was doing the same thing to me ( failure 3 times with KT88nd the 5 fuses were blown ) some how since then no more problem. I guess it could be just bad luck. Well what do I know.

Hi JJ. Sorry to read this.
Do not take the decision to part from them just because of a fuse after some tube failures. I had one of the fuse of one of my CCQ blow away 2 months ago. Fuses are here to blow and that is good when they do.
Many things can happen when you power on a tube amplifier.
Unfortunately our domestic AC current can be of very poor quality during very short time. You want the fuse to blow when this happens ! Do not blame your amp. Blame your AC company provider !

But I would still test your the tubes just to be sure. It could be a tube getting bad. Moreover, did you recheck the bias about 100 hours after changing the last 300B's ? If the bias changed and was not adjusted, you can have there an other reason for a fuse blow.

As many said before, tubes are by nature unreliable. They compensate this by sound quality. There is a price to pay for every thing in this world.

There cannot be any "design flaw" in your amps. Because they were made by one of the best tube circuit design experts in the world. Would you question a simple multiplication made by a Fields Medal mathematician ? Are you kidding ??

Now, the most reliable tubes on earth have your first name on them: JJ.
Please try them if it appears again that one GL is faulty. And be sure to set the bias correctly and recheck it after 50 / 100 hours.
Good luck buddy !

Will do. Thanks Jerome. I am just so frustrated as every dozen or so times I turn these amps on they fail. Maybe I should try the JJ tubes. I just am hesitant to install tubes that were not originally supplied with the amps.

Whatever the issue is it really takes the fun out of just switching on your gear and relaxing to some good tunes. Now I just stress every time I turn it on to see if it works. iPod?? Maybe soon.

I understand.
You should not be too worried in putting other tubes. Great tube designs do not really care so much about various tubes. You'll get very small differences in sound imho between GL and JJ. ( Of course, WE or Cetron may be clearly better but you cannot find them !) But with JJ you will have a much higher reliability.
Nagra uses 300B JJ tubes in their 300B amp and 300B integrated. And they both sound really fabulous.
 
I will try them. Nothing to lose at this point. Thanks for the advice.
 
just curious to what your dealer or shindo had to say about it?? did you buy them used or new? this should not be happening, and buying more tubes and fuses to try to fix the problem is not what you should be doing. i had a similar problem with a BAT amp. the one that i bought used was perfect and ran beautifully. the one bought new was a nitemare and every time i turned it on the same anxiety over what tubes or fuses were going to blow. after 3 trips back to Bat and 6 months of headaches i finally got it fixed and it was something small and stupid they kept over looking. once it worked properly i sold it immediately .
it should go back to the factory and get fixed properly , especially for the amt of money you laid out for them. good luck and let us know how you remedy the problem.
 
Any amp that was this unreliable I would have dumped faster than a used prophylactic. This is supposed to be about a hobby that is fun and relaxing and not one where you sweat bullets every time you power your amp on. You have either had an incredible run of bad tubes or it's simply a defective design or a defective unit. You have already come to that conclusion and I agree with you.
 
For the money spent on these amps they need to go back to the dealer and have them sort it out and give you a loaner until fixed. Swapping out all these tubes and fuses to have them continuously blow is BS.

+2.

BS is BS, and at their cost you should expect something more reliable. And I adore the Shindo sound more then any tube gear I've heard to date, but this seems freaking crazy to me, if all else fails?, I'd find a very good technician like Michael Samra over on AA, would fixed my beloved EL84 Integrated along with an ex-friends Sophia Electric 126S and now both are working up to par, without a hiccup to say the least.

But there's no way in hell, I'd just be writing this off, and it would've been sent back after the second incident. Good luck with this matter, but it saddens me to hear/see topics like this. But tube components do have their problems after all, and seem to need that much more attention compared to solid state - trade offs I know, but this is one of the main reasons I'm looking for a solid state backup, as one never knows..........
 
I certainly agree with others, that there may be an issue with the amp. It should get looked just to be safe.
But I suspect you will find the problem is with the Gold Lion 300B's. To date they are the most unreliable 300B out there. I've had bad ones right out of the box.
Had the same problem with Gold Lion KT88's a couple of years ago. Turned out to be a QC problem, and once sorted out no problems since. This 300B is relatively new on the market and I think there maybe some production issues.

Modern tubes just arent the same quality of the 50/60's tubes..........Sorry to hear about your problems . Maybe a solid state amp with your preamp......D'Augstino makes a wonder solid state amp. I have thought about this myself.

I cannot believe that you are suggesting a SS amp to a Shindo amp owner ! :D
I am not saying that the Dag is not a heluva of an amp, but still, JJ. loves Shindo.
There will be a solution to this problem. We are talking here about state of the art tube amplifiers.

You allowed to have your opinion as I am sure you have tried the D'Austino, right?
Yes I use tubes too but one needs to keep their mind open and sometimes whats best for you is not best for all. So thank you for your opinion. After all you own Harbeth and must be a man of great taste and knowlege
 
All the Krell amps that I listened too made my ears bleeding so I did not dare to listen to the d'Ag....:lmao:

I will second that too, High end customers and high end product deserves the very best of service. Which I know Jonathan agrees too.
 
Point proven you might listen before you speak and actually personally I am not a wilson fan but I have to say I had never heard them so good untill i heard them with D'Austino.....just a thought.
