Elizabeth, While various circuits have an effect on tube life some tubes simply last longer than others. While one tube may last only 500 hours another tube may last 2,000-3,000 hours or more in the same circuit. Unfortunately the better sounding tube can have the shorter life.

Yes, my HP-100 was 'updated' for final status before Hovland quit. I've tried several of the JJ's but the ones I used seemed a tad noisy and not as 'organic' as the Sophia's or the Mullard NOS. I may just try the Genalex and go from there. The problem with getting NOS Mullards is that you never know what you are truly getting. I have NOS Mullards that came from so-called respected on-line dealers that went way noisy in just a few months... |
stickman..i recently tried the 'genalex' 6922 tubes in my preamp and really liked what i heard ..but...i had an acute ground loop issue with them and replaced them .i did like the sound...as for the ' tube life ' issue...i recently bought a pair of the new sophia electric 'royal princess ' 300B tubes for my amps and even if they only lasted 500 hrs i would still buy them again due to their superb sound...hopefully they will last alot longer.. |
Shoot an email over to Jim McShane when you get a chance. He is very knowledgable and provides great service: jimmcshane@prodigy.net I don't think he recommends the Genalex with a phono stage, but he will give you plenty of options. His website is here if you want to peruse his selection first: http://www.mcshanedesign.net/tubes.htm I have no association with Jim, just have had very positive experiences. He is very forthcoming with his expertise. |
