"I have been deluged lately with people asking about issues with their tube gear that they have decided for whatever reason must be the tubes. Occasionally it is, but at least 75% of the time in my experience it is not. So I wanted to make a few points and pass along a few tips to help people out. 1. The #1 cause of noise problems with tubes is poor contact between the tube pins and the socket. There are a wide variety of possible causes, dirty pins and/or sockets (in the case of a noisy new tube the socket is the PRIME suspect), socket contacts that have been stretched out or worn out and don't make good contact, or in a few cases, bad solder joints on the socket itself. A tube socket - even really good ones - are not sophisticated, high reliability connectors. You won't see tube sockets in critical applications because they simply are not reliable enough. Do yourself a favor - clean the tube pins and sockets every time you change tubes. A bottle of DeOxit D5 and a handful of good old fashioned pipe cleaners works great for octals and other large pin sockets; for the miniatures, D5 and the little tiny dental brushes for cleaning between your teeth (another drug store item) do a solid job. BTW, D5 is good to 400F - so don't lose sleep over it because of something you read on the "Hi-Fi Hysteria" forum. And it doesn't gum up either. Spray some in a paper cup and let it evaporate - you'll be able to see for yourself. Sometimes you swap a tube and the new tube is okay. so the tube you removed must be bad, right? NO! Sometimes the scraping action of removing and reinstalling a tube in that socket is enough to temporarily restore contact - and fool you into thinking you have a bad tube! KEEP YOUR SOCKETS CLEAN!! Honest - only a few % of the tubes I get back for noise are bad. Most go on to play fine in another socket." Last edited by jdandy; 05-04-2014 at 07:19 PM.

Gortnipper,
This sounds like good advice, once I get that pesky screw out! :-)

Its is different, not better or worse. Think of them as different vintages of the same wine. Don't get hung up in the audiophile comparison game, just play some music. The best thing you can do for your Giscours is use it to the fullest. Proper amp, speakers, cables, sources, transformers etc. 99% of people never hear half of what Shindo can do from mismatched speakers and associated cables and accessories.
Where did you purchase this Giscours? Hopefully your dealer can help you get the most from it. Jonathan
