- My piece of mind on using Ecc81/12at7 on the phase inverter position. if you like little less gain but more detail, this is the vid for you! :) Hope you enjoy and subscribe for more!
Let me know in the comments which is your favorite ECC81 /12AT7 and why! :)
Thanks for the video really it is a value information 👍
Thank you for posting and bring back the interest on the ECC81/12AT7 tube .......the good news is , they are good, still plenty nos and not outpriced>.
some brands have a kind of chromatic overlay on the sound .......
All the tubes you mentionned are good , the Ei is indeed build on the tooling bof TFK but not with the same quality materials and chemistry property of the genuine TKK tubes , copies yes but they sound nothing like the TFK and the life expectancy of
And I thank you for this comment! I need to find more Ecc81's . TFK, Valvo is on my want list :) you should also give a try to this Marconi Italiana Ecc81 made in late 50s, sounds amazing :)
@@ecc8344 The Italian made Marconi is in fact an RCA BP linced made tube ( materials provided by RCA ) ..........that's the secret why it sounds so good !
Do you live in Eyurope ? ....maybe I can help you finding some of the ECC81 tubes you're looking for !
Yes Im Europe :) thats why im calling it Ecc81 not 12at7 hehe..maybe if you know some good deals would be good. I usally find people selling tube lots and find some gold in there for peanuts :)
Great tube lineup but your missing the best one. My gold standard, Mazda 12at7wah. Coming in close 2nd, Valvo 6201. Cheers!
Dont have those 2 yet, maybe one day :)
Are there recommended tubes for v4 effects loop position?
No, this is for phase inverter..the very last preamp tube before power section. If you have a FX loop tube just like my amp it can improove the signal and clarity of FX. Hope this helps👍
Ok thanks! What do you use in your amp for the FX loop if I may ask?
