REVIEW AND COMPARISON: Eddie Current Balancing Act and SUPER 7 - Page 7

@Stavros

    Thanks for your suggestion :

     I will try those combinations , I think I have all those so I don't have to do the

tube hunts

    

I would use:

Driver: Brimar CV1988

1st Pair: RCA Gray Glass 6SN7GT

2nd Pair:Sylvania 6SN7W Short Bottle, (Lower Mica Inside Base)

3rd Pair: NU 6F8G

 

@CeeTee : thanks for understanding, I am also a little bit embarassed about my computer illiterate.

 

I may use the round plate RCA 6F8G's and switch with the gray grass RCA 6SN7GT.  Brimar or STC CV1988

is an excellent idea or Mullard ECC33.   NU6F8G 's are wonderful tubes as you suggested.

I would also try an ECC35, or an ECC33 Yellow Label for drivers.

@Marv, Those picturs are beautiful. Do you know how much is the output of the speaker post? Can we use them to drive the AKG K1000? I hope it can be ready for my Christmas present. I am ready and my tubes are ready. I don't think we need to used a perfectly matched pair of 6SN7's and a pair of the same 6SN7's should be on the left and right at the same row , is that correct?

Only if you're the President, then you have to do it like 10 times in one speech.  At least it's not as difficult a word as Orion, excuse me, Oreon.

I would only dare to hope, I mean, have the audacity to hope. We could definitely on the precipice, I mean, on the doorstop of impropriety here.

Supposedly yes on K1000. Tubes do not need to be matched. Isn't that awesome!

 

And yes, it looks fricking awesome! Not like that ugly prototype.

Correct on both counts.  I asked Craig specifically about matching and to sum up, after a long in-dept explanation, he said it was basically a non issue w/ the design of the S7.  If you want more technicalities I'm sure purrin can chime in.

Yes , Craig answered back .  He said the Super 7 is more powerful than my BA, may be the same as 2A3.

If the input if 3V it can drive the AKG K1000 and HE6 with no problem, that is really good news.  I can set my output

from Weiss DAC 202 to 3V  or even up to 8V

The tubes don't have to be matched and the position does not matter , just place similar 6SN7's each on opposite

side , doesn't need to be on the same row.

He is waiting for the Electra transformer,  I heard the bad news that he smashed his hands and if he has to do

the transformer by hand by himself, that will cost some delay.

He said that the super 7 is possible before Christmas but more likely after that

The BA is really not that powerful ~1W into 16 ohms. It sounds powerful with most cans though including the LCD2/3.

I can use my BA to drive the AKG K1000 and HE6 at 2 oclock by setting

the output of Weiss DAC 202 to 3V with balanced in and out.

I think the output of super 7 is About 2.5 watts, 3V in should drive the K1000

This is the info from Craig, so I am happy that it can drive both phones

even I use unbalanced in and balanced out.
