I wouldn't call it trouble, because I like building things. I'm a tinkerer at heart. This is the first tube anything I've ever built, so not much to compare too. I like it and it works well with my Altec A7's. Building some Paramours now to go with it.
Re: C4S
Thanks for the offer of the C4S, but I already have some. So, which Mullards do you have?

Do you want some C4s's. I have a foreplay that is collecting dust.
Beautiful!

P.S. I also have some NOS Mullard tubes...

12AU7/ECC82 CV4003 Mullard. HEAVEN!!!! Attn: Rogue and Conrad Johnson owners and those with other "picky" preamps!! I had about enough of the PV-10, 11, and 12 being a bit tough on 12AU7s, and was suggesting folks stay with Chinese or RFT even though they don't sound as good as a Mullard. We now have a test where we can supply you with premium tubes that are quiet and don't go microphonic.
The Mullard CV4003 is a wonderful tube British tube with the midrange we crave. For premium select $35. For Private Reserve $40. For Rogue/CJ owners, we have a special test that only 5 out of 100 will pass. $45 each, but you won't have any more problems, so it's worth it.
I have the $40 ea type.

What is this nonsense? The Mullard ECC82 is a field scan valve (an application that does not require low distortion. The one remarkable feature about this valve is its consistency between manufacturers and samples. Selection is not necessary. They are all equally poor for audio.
ECC82.
Hi,
He,he...and if you really want to listen to the worst of this kind try the nickel plated 6189 as was used by the French postal services and usually made by Cifte...yuk.
Instead of spending money on so called premium 12AU7A/ECC82s it would be much better to mod the preamp and use a similar gain valve such as the 6CG7/6FQ7 or better still a 12BH7A.
Cheers,

Hi,
Not all that many tubes were designed with audio use in mind anyway.
And amongst those that weren't designed with this particular use in mind, there are a lot of various types out there that all sound a lot better than an ECC82.
Cheers,
Hi,
But, just because a valve was not designed for an audio application in the first place, does not necessarily mean it'll be no good for audio.

I take your (logical) point. Sadly, very few valves not designed for audio are any good for audio. The ECC82 is very definitely an astringent citrus fruit.

That too might be true. The funny thing to me is the number of valves that I knew in my previous RF life (teens) that have become "standards".Sadly, very few valves not designed for audio are any good for audio

I take your point. There are a few other applications that also require low distortion. RF front ends, FDM telephone amplifiers, and good IF strips. I'm not quite sure what the variable-mu ECC189 is doing in your list, but the EF184 is one of my favourites. It's a good triode, and it makes a good constant current sink.

FU! I love 12AU7
