Mullard never made a 6SN7

Didnt Mullard make some ECC34 or CV1988 tubes. Can these be used in place of the 6sn7?
I doubt thats what is meant though. I think these are fairly rare.

I've had the Brimars when i had my first SP amp. But I thought for sure that Mullard had made some black glass CV1988 tubes. Were these made by Brimar for Mullard?

Bravo. Greetings from EddieWood. I can see Capitol records.

Sounds like something wonderful here. Thanks Ironbut.

I have a black glass pair of Mullard labelled CV1988's but they are clearly made by Brimar

This is now up for sale on the Eddie Current website.

Time to start scraping together some cash!

Dear Santa. I have been a very good boy. So, um, how 'bout it? Regards. Stretch.

I do wonder if 72dB of gain may be a bit too much for all but the lowest output moving coils. I guess there's nothing stopping you using the MM setting if you have more gain in your line preamp.

72dB is a little high for the higher output MC but there are other pre's that are up there... most are in the 60's ... using MM is one way or it is possible to swap tubes for lower gain as well.

as long as there is no clipping, you would just not use as much volume.

Glad to see it hit the site... It makes it real and makes me want to order.... need to resist for a little bit... but this has pretty much become the pre that I want for my system...

Cheers...

The prototype of the TA that I heard at CanJam sounded wonderful, even under meet conditions.

I have to resist the temptation since I'm already awaiting delivery of a new headphone amp from Craig.

the 5751 tube is a direct replacement for the 12ax7, which has much lower gain and many find to be better sounding, though some of them can be quite pricey, such as the sylvania gold brand gold pins.

Regarding the 5751, I prefer the sound of these to just about any 12ax7 but you need to ask Craig about them for use in the TA. If it has a passive RIAA eq circuit, it's likely that he'll advise you not to use a lower gain tube like the 5751. Many time the eq circuit is placed in between the stages and the difference in gain will effect the eq.

Regarding the Mullard 6sn7. I seriously doubt that Craig will offer any NOS tube as stock. As an option, yes, but finding a reliable source for NOS tubes is a nightmare as well as the warranty issues. It may be that there is a Mullard branded new production tube (made in Russia just like the Mullard branded 12ax7 that I'm sure are the stock tubes) that he's using that just hasn't hit the tube sellers yet. I'm sure it would be something like the EH 6sn7.

My phono stage has more gain than that and it works great with all the usual suspects.
With the very low output MC's, you'd probably be turning up your volume pretty high (which is fine).
Having too much gain is the last thing you have to worry about with phono stages!
