12ax7 vs 5751

VERY interesting thread. I recently bought a Thor ta1000 and am very impressed with it but would like more of the sound you are describing.(3d and depth) This is my first tube component of any sort and I was told to go with GE 5751 triple mica blacks. If the potential for improvement is anything close to what you have experienced...then I have a lot to look forward to! I am anxious to hear your update when the 5751s come in.

I didn't like the 5751 until I found some good ones. Give A'gon member Paul_lindermann a shout,he will fix you up.

hiya guys,

i`m still waiting on those tubes though i got a matched pair of sylvania 1970`s grey plate disc getter 5751`s through the post. i bought them because they were very cheap and have nothing to lose as they were cheap.

the sylvania`s for the price are very respectable. nice and clear, nice bass and lots of detail. they`re not in the same league as the others i`ve tried (12ax7`s and 5751`s) but i wouldn`t say they`re that far behind. they`re a used pair so no breaking in has been required but i have let them warm up a couple of hours. the sound compared to the ei elites is thinner all round but again i don`t want people to think they`re rubbish. far from it! they still have a very nicely weighted sound, just not as weighty as the others.

it`s driving me nuts waiting for the ge 5751`s and the black treasure kt88-z`s. i was lead to believe the black treasures were posted on the 18th but i`ve found out they were only posted on the 29th! so i have more waiting to do! grrrrr lol. the ge 5751`s should be here anytime now.......hopefully!!!

i just googled the thor ta1000 pre amp. wow! very nice looking! and very unusual. i`ll let you know straight away when the tubes arrive i`ll do an initial review of the tubes and then a more in depth review when they have more hours on them and when i can give them a good prolonged listen. you might want to think about the telefunken 12ax7 tubes. the ei elites are apparently based on the telefunkens and made with the same tools that made the telefunkens. i have to say that so far the ei elite 12ax7`s have blown everything else i`ve tried out of the water! a truly stunning sound! just dubious about them turning microphonic after a few months use. so far they`re quiet. one is just very slightly microphonic and i do mean its hardly noticeable. the ei elites are very holographic and very 3 dimentional and the depth of sound and tones has to be heard to be believed. a word of warning though......what works in my amp may sound different in yours but i guess this is where the fun lies in finding what works in your system. so far i`ve been extremely lucky finding what works in my system. definately not skill! i`d hardly call myself skilled as this is my very first tube amp. i hope this helps. more to come very soon hopefully.
