Thanks, i'll try to find the 12BH7. The goal is sonic improvement, not replacement for a dead valve.
The pinout does not need to be the same, though it would be nice that the heater voltages are 6.3v
In fact i'll probably buy a few of the models you all suggested and give each one a try.

Direct equivalents are the 6189 (me no like) or 5814A (I like better), 5963 etc.,etc...

Hello, I have just bought a pair of Philips 6189 for phase splitting in my Copland CTA-501 from my supplier: www.demostenes.no
He says 6189 - Equivalent to ECC 82 and 12AU7. Manufactured by Philips ECG (=Sylvania) in US. This is a military NOS valve. Probably one of the best ECC 82 type in amplifiers such as Conrad Johnsen and others.
Since I am new to this, why don't you like 6189?
Best regards
Hi,
If it's for a phase splitter you probably won't notice the difference.
In Europe alot of these 6189s were used in governmental services.
Quite often they looked as if they had been entirely chromium plated and they sounded pretty metallic too with steely highs and little or no soundstage depth to speak of.
I still have to meet the first person telling me they liked the way they sound.
This is however entirely subjective so YMMV....

Use E80cc instead. Made by Amperex mainly. If you find Tunsgram even better. It has about 80% more gain, uses .6A for heaters @ 6.3V and it comes in el84 style bottle. An SQ 10000 hour tube that will broaden your stage, mellow your highs and pump up your dynamics. Sonically non metallic like the US 6189s but errs to the mellow side if mixed with Mullards etc.
Hi,
For starters, an ECC82 has got nothing to do with an E80CC and vice versa.
Oh yeah, and you'll likely find ones made by TFK too, although not easily.
E80CC is a Philips valve if my info is indeed correct, so you'll find them across any Philips associate.
Siemens, OTOH hardly made any valves at all, with the possible exception of the Cca...
Types needed for their medical services.
Whatever valve they made was darn good though...That typifies Siemens policy though, when they want to, they can make a mockery of any manufacturer...
The Epcos series of caps being another example.
Unfortunately the company's policy is also to kill off the outstanding product...
They have so much cash it would make you think about who lost the war...not just that, they also freeze so much briliance that it make you wonder why you wanted to be an engineer in the first place...
Any more of this will probably get me fired...not that I care all that much anyway..........
George, here is where the WMD could well be stashed..............

Get real, please before I call you all rude names...
I guess you can start by calling me a rude name as I really like the E80CC
(Excellent results in Nina preamp remember).
But what am I missing ... why the name calling please Frank?
Re availability:
Mullard/Philips are common; gold pins and no holes in the plates, it's Mullard/Philips whatever the label.
Tungsram are hard to find, but you sometimes find them badged as something else; I've managed to get 6 this way. Steel pins and 3 holes in the plate, it's Tungsram.
I have a moderate preference for Tungsram but could easily live with Mullard/Philips. My experience is that either type is far superior to any ECC82 I've tried (about 6 types) in just about every way.
OK Frank, what else would you suggest as a preamp valve, gain in the range 15 to 25, running at say 6 to 10mA? Need not be pin compatible.
Hi,
Mike,
Don't worry, you designed using the E80CC which is ample proof that you know both the valve and the electronics.
However, the E80CC is certainly not a replacement for an ECC82/12AU7A.
Quite often it will work but 9/10 it won't work properly.
If the thread heading would have stated " What's a good alternative instead of designing yet another splitter with the 12AU7, then that would have been something quite different.
