12ax7 vs 5751

I have a pair of each that test way good.The RCA is Triple Black Plate 1960. Really did not like them in my VTL 5.5 pre-amp. Went back to 12ax7, like some one said in what circuit are you using them in means a lot. They test on a B@K 700 with 22 being minimum good 35/35 and 34/32. The RCA i got from Jim McShane.

Yeah I think this Thor was a steal. Had cap upgrades,etc. Today I was cracking up listening to the Commodores. I went from a Marantz receiver as a pre to the Thor, so my cd collection seems brand new.
Are the GE tubes that you ordered (d getter) similar to the triple mica black plates? I am so new to this..it isnt even funny.
How about Phillips Miniwatt 12at7? any experience with those?

hiya yes the ge`s are d getters triple mica black plates (the really good ones). i`m waiting to pounce on the postman (not literally!) this morning. i`m so hoping he has at least one package for me! i also ordered the telefunken 12ax7 smooth plates yesterday. should get those tomorrow. i want to see if there`s any difference in the sound quality compared to the ei elite 12ax7`s. thats gonna be interesting!

unfortunately i have no experience with the phillips miniwatt 12at7`s as my amplifier doesn`t accept those types. i`m kinda glad too! this tube rolling is getting expensive! i really musn`t order any more! i`ve already built up a small collection of 12ax7`s and 5751`s. i must say i`ve not heard any lousy sounding tubes out of any of them. they all bring something unique to the sound of my amplifier but i will say the ei elites are truly stunning!

we`re both in the same boat as newbies to tubes! i was kind of the same, i went from a denon reciever straight to a tube amp and i know exactly what you meant saying you were cracking up when listening to the commodores. i`ve been exactly the same with some of my cd`s too. i just cannot wipe this stupid grin off my face when i listen to a cd! i feel like the cat that got the cream!

the funny thing is i was listening to music on youtube through headphones on my computer and listened to some of the tracks off that dave gilmour cd on an island. i actually heard more detail through the headphones and they`re only cheapies too but it`s made me think that all that extra detail maybe is to come when i get all these other tubes i`ve ordered but i`ll have to wait and see. once i`m satisfied with the sound in all this mixing and matching i`ll just concentrate on those certain tubes i`ll be using and get spares. all the other tubes i`ll probably sell but i`ll hold onto them maybe a few years to see if they go up in price and hopefully make some extra money.

i`m really excited at the prospect of getting those telefunkens. i got them at a fantastic price off ebay last night. they`re supposed to be the best.

i have to ask.....did the cap upgrades make a difference. i`m thinking of doing the same for my amplifier using mundorf silver/oil caps in the pre amp stage. i`ll be starting a new thread on this topic once i`m happy with the tube arrangements and sound. i bet that`ll be a very interesting topic. keep your eyes peeled for that one. i`, also thinking of upgrading the speaker cables at some point to chord epic cables but that might be some time off yet as those cables are pretty expensive!

i`m kinda glad too! this tube rolling is getting expensive! i really musn`t order any more!

Oh just wait until you start rolling vintage output tubes or try some current production EAT's!! Then just think of all the combinations with all the input and driver tubes. I just ordered some Gec and Tesla KT88's.

Xti16 stop right there!!!!!! lol. i can`t hear you!!! i kind of had a little delve into the gecs, wow! very expensive! but i bet they sound amazing! let me know what they`re like when you get them it`ll be very interesting. not heard of the EATS, i`ll do a little research into them and the tesla KT88`s. i was thinking of those psvane KT88-t`s too. i`m just looking around my room to see if there`s anything i can sell lol i can see me ending up sitting on a wooden box listening to the only bit of furniture i have left lol. funny enough i do have plenty to sell that will make a good bit of money but my sensible side tells me to keep the money for a rainy day, but then i have this little devil on my shoulder poking me in the ears until i give in!

just a very quick update on those sylvania 5751`s in there currently..... they sound really nice. nice and clear and a really nice focused soundstage. listening to them right now with the volume cranked up a little louder than usual. there`s nothing really lacking in them anywhere. they have a nice punch to them too but not the slam that the ei elites gave me. but there`s lovely detail all through the frequency extremes. damned good considering i only paid $18 for the pair. stunning bargain!
