my wife complains I spend too much on tubes. maybe I can shut her up with this?

Sure you can, but she will probably borrow some of your 6sn7 tubes to see which ones make the most difference. Maybe a tungsol bgrp, I heard they help tighten the bottom end....

Or else I can try to tone my beer belly. 

Any of you guys can describe the sound of the National Union NAVY 6sn7gt?  I am talking about the long one.  Any info?

opps double post.

The one with the grey glass?  It has better resolution than the black glass NU but I didn't care for the tone.  Imagine the RCA grey glass only shouty and edgy in  the upper mid lower treble range instead of lush.  May have just been that tube, it was noisy so maybe it wasn't run enough to be broken in.

I meant this one. 

Processed By eBay with ImageMagick, R1.1.1.||B2||T0JKX0lEPTRmNjc4MmQ3YTQ0NzI0NjkwNGY2N2EzYzg2NTU1NzA1MTM5MWNiMDI0OThkfHxTRUxMRVJfTkFNRT1pbm5vdmEtd2ViLWludGVybmV0fHxPUklHSU5BTF9FQkFZX1FVQUxJVFlfU0NPUkU9NHx8Q1JFQVRJT05fREFURT0zLzI2LzEzIDk6MzAgUE0=

Most other NU 6sn7gt have like 3/4 in black glass and the other 1/4 in clear glass.

Yep, that's the one.  They are rather rare, the black glass is far more common.  I'm not sure my impressions are all that valid given the circumstances of the listening session, but FWIW I didn't care for them.  I know some people pursue these particular tubes pretty aggressively though.

Can I borrow it when you are finished to tone mine please?

Promise I'll be very careful with it.

No need to send it with a tube I'll use one of my own.

 

As for the Grey Glass NU they are very nice tubes.

I tried them with my SP and they sounded great.

Never tried them with my Glenn OTL yet.

Has anyone used/tried the Hytron 6F8Gs?

post #3369 of 4081

What's do you guys think of using an 12AU7/6SN7 adapter? I got some nice 12AU7's I want to tube roll in my DV 336.

Good question.  I don't know.

These look more like Tung Sols to me.

The Tung Sol have different supports at the top mica.

 

They look like Sylvania to me too.
