SEX tubes

[i luvmusic 2]

Do i need a match pair of  tube for the S.E.X.?
Is it important to match the  tubes for S.E.X.?

THANK YOU!

As I understand it, the 6DN7s are quite common but matching may be a difficult endeavor and is not usually done.
I'm currently using one Sylvania and one RCA selected for their minimum hum during low passages and between tracks.  The channel balance seems right and using two different manufacturers doesn't seem to make a difference in overall performance.

Sounds like a reasonable price to me. I used to buy 6DN7 and other similar tubes for Wooaudio's WA6SE. They are around $7 each on the lower end for NOS.

Those test results depend on the tube tester used.  For example on the TV series military testers there is a scale from 0-120 and the spec for 6DN7's says it should test with a minimum of 40.  I dont know what a good 6DN7 should test at, but if its 80-90 on one of those testers i would call them perfect.

I think the only time i paid more than $10 a 6DN7 was for some Tung-Sols, they were so rare i just didn't care as i had to have them, and a few others on eBay had the same mentality.  As above anything from $5-10 seems to be the norm.

I don't see them on ebay for less than $10/tube and THANK YOU! for the info.

Is it possible to used a 6SN7 tubes for the SEX amp?

Thank You!

The 6SN7 will not work.  The 6DN7 is special.

 

[i luvmusic 2]

If i try it anyway would I see a FIREWORKS and hear a KABOOM?

 

[Paul Joppa]

I have never tried it, so there's no way to be sure.

But in theory it might work acceptably - for a while!

The heater voltage will be a little high, and the dissipation in the power section will exceed the spec; both of these will reduce the life of the tube. It should at least be a -GTA or -GTB version, the standard has a much smaller dissipation limit.

 

[johnsonad]

Go big or go home Paul!! Lol

 

[i luvmusic 2]

I have both the GTA and GTB so i guess i will be the first one to try these.


THANK YOU!

 

[fullheadofnothing]

Use ones that you didn't pay much for...

 

[i luvmusic 2]

OK THANK YOU!

I will be using the 6H8C for now to see how it goes.

 

[JamieMcC]

OK THANK YOU!

I will be using the 6H8C for now to see how it goes.

Make sure to let us know how you get on the Russian 6h8c are inexpensive enough to be regularly disposable.

 

[i luvmusic 2]

I don't mean they are inexpensive/disposable,It just happened that i paid $3 a piece compare to my other 6SN7's .
I hoped i did not offend anyone.if i did PARDON ME...

BTW You guys should give it a try it does work and sound nice too.

 

[mcandmar]

I can never tell if PJ is being serious or just trolling us

6H8C is basically a 6SN7GT and limited to ~300v plate voltage so it may not be suitable.
