I purchased an ECC82 to try out with my new EE DAC. Will be my first bit of tube gear and hoping I like the sound.

I tried to extract from all the posts the tubes folks claimed to work for them:

1950 Raytheon blackplate 5814WA
Amperex 7316 PQ
CV4003
Philips pinched waist D getter E80CC (82?)
Siemens 5814A long plate
Siemens silver plate
5751 Sylvania gold label black plate triple mica getter

I'm using a Mullard right now with a Mazda as close second

You should NOT use the 5751 as this is a 12AX7 variant not a 12au7 variant

13D5 also works very well.

I'm curious if Alex can approve use of the E80CC, known to be much more linear than the 12AU7, which runs 2x filament current at 600mA.

5814 is a good choice too which runs only 50mA more current.

One of many threads.

Alex says that besides a 12au7 tube, that a 12AT7 tube can also be used in the DAC. The 12AT7 has a little more gain.

Yes, an E80CC can also be used in the DAC for sure. Alex approved.

Awesome news on the 12at7's! I have some primo nos tubes to try, such as the Genelex A2900, the Brimar yellow T 6060 and a Valvo pinched waist blue label 12at7 (this may be my favorite tube of all Ive tried)!

I an breaking in a NOS Phillips gold pin E80CC - very pleased so far. Improved air, better imaging, more detail. I have been looking for "more cow bell", and I think I finally found it!

Cool, I've got some Telefunken 12at7s to try once my damn media server is repaired. Apparently the problem isn't my motherboard...

I know AudioClyde wasn't so hot on his E80CC roll. I haven't pulled mine out of my amp since rolling them (SET 6V6).

My main server's SSD just bit the dust out of blue btw - what a pain.

Doc,

You sure have a lot of computer problems

doctorcilantro · « **Reply #12 on:** 4 Oct 2010, 11:11 pm »

I know! Luckily I have a LOT of backups. All restored, drive (G. skill Falcon SSD which lasted 1.5 years behind a UPS) RMA'd, and in the mail. My "Hifi" client (I use J. River mc15) sits behind a Brickwall suge protector and EP15 regenerator.

The E80CC I am listening to may not be for everyone. It is similar to the Siemens I own and way different than the 1950s Mullard I had in just prior. While the Mullard is fantastic on vocals, it lacks the air, detail and top end of the Philips E80CC. For me, there is not a clear winner - they all sound great, and amazingly different.

Speaking of tubes on the EE Minimax, who is running with the tube guard in place and who removed it?

Hello .... I would like to obtain a Siemens Silverplate to try in my EE DAC .... Can anyone halpe me locate one I can purchase or even try ?

Thanks

There is a possibility I may be willing to let mine go in the near future depending on how an experiment works out for me. I may decide to keep it, but I'll let you know/give you first crack at it if not.

Is it sure that we can use 12AT7 tubes??? I have a GE 5 star tube that I can try but will like to know if thats ok to use in the EE DAC?

Thanks

Gopher · « **Reply #18 on:** 25 Feb 2011, 01:04 am »

Yes. The Alex that Bill refers to is the DAC designer. I have personally used a 12at7 in my DAC with no issues... beyond not liking the sound.

You did not lilke it with the 12at7? You prefer the SS or the 12au7? Which 12au7?
