Unless you have a Premier 17, which uses 4 per channel!

Thanks, Ron!

to my knowledge ET2 comes with NOS Mullard
M 8080 equivalent 6C4/EC90/CV4058/6100

Maybe when it was new. Today these tubes are no longer available from CJ. You can find them through other sources on the web but I do not know how reliable they are. If you order from CJ you will get a Phillips 6C4.

Still better than the 10 per channel in the ART

Ronenash, as best I can tell...this is the "de-facto" replacement for the Mullard M8080? WV also lists these other "6C4s"

Watford Valves :: Product - 6C4/EC90/GENERAL ELECTRIC
Watford Valves :: Product - 6C45PI/SOVTEK
Watford Valves :: Product - 6C4WC/JAN PHILIPS

Any thoughts on whether they'd also work in place of M8080s...on my ET-2, for instance?

The 6C4 is the american version of the british 8080. There is no problem using it as a replacement to the 8080. CJ currently use the 6C4 as the 8080 are no longer available.

So all of the above should work? The Sovtek 6C45 was the one I wasn't quite sure about. Thanks.

Wow 2100 to add SE....

So glad I bought the ET3SE for the additional 1500 over the ET3.

Took about two weeks of playing the Pre for 10-12 hours a day. I just enjoyed music during this time not worrying about the sound.

The Mat 7DJ8 and the EAT 6922 are my two favorite tubes so far.

Not sure about the Sovtek but all 8080 and 6c4 are 7pin tubes as opposed to the 6922/6dj8 series which are 9 pin tubes

Good to know you like the Mat 7dj8. I bought two of those to have just in case I really like them and they are no longer available. The EAT is a major investment which I will leave for some time to come.

I will wait for this weekend to replace the EH for the Mat. The preamp should have 150 hours on the burn in meter by then.
