In Reply to: 12AU7 as a buffer - suggestion of brand/model. posted by beppe61 on February 13, 2007 at 23:42:41:
... an RCA 5963 black plate or a Tung-Sol 12au7a. There are many to choose from and try that are not expensive.
Thank you very much Sir for your very kind and helpfuld advice.
Actually I felt that an 12ax7 in 12au7 was not a smart move.
Nevertheless I have been impressed by the result.
Maybe the original 12au7 is quite bad.
As I said the duty for the selected 12au7 is that of a buffer.
Actually I am putting down a list of very good 12au7 tubes.
Is there the problem of "fake" pieces with them as with Telefunken NOS tubes ?
Thank you so much sincerely.
... pick up 4 or 5 common 12au7 variants (5963, 5814a, 12au7a, ecc82, ...) on ebay for a few dollars apiece and see what caught my attention. The different influences of the particular tube on your music will be noticed.
I'd look for a seller that had several of these tubes and do a 'combined shipping' deal to save money on postage. For $25, you can get a nice assortment of good used tubes to try. If you find one you particularly like, you can then buy a true NOS of that variety.
Thank you Sir but I have already settled for a more energetic sound.
So I am looking for a very "aggressive" 12au7 tube.
If this kind of tube does exist.
Thank you very much indeed.
