Well there's the Kentucky Derby (oh the infield!). And the rolling hills of Kentucky. Mammoth Caves. And of course Mint Juleps. And for dessert: Derby Pie!

 

t'ain't nuthin' bedder than that, I'd say... then again... there's Amsterdam.

longbowbbs congratulations, Santa came early for sure.

Your system looks very neat.

 

BTW I like your cat, how old is she, around 3?

Can I exchange her (short term loan of the cat) with my pair of 596?

6BL7 test #2 - I thought maybe I could perk the sound up by running a more lively driver so I swapped out the Hytron for a mouse ear Tung Sol.  It has better extension on both ends than the Hytron does.  It ended up sounding worse though, and has heightened my appreciation for just how good the midrange is on the Hytron GTs.  The organic and natural depth of the Hytron seems to shine through really well, and gives me the impression that the 6BL7 is adding little color of its own here judging by how different these two 6SN7 tubes sound in this test.  With the Tung Sol the upper mids gained some dominance making everything sound thinner, but the lack of top end is still obvious.  There is a "smallness" to the sound for lack of a better word, it screams "you're listening to a recording" rather than feeling like real music.  Too little power is making it out due to the extremely high output impedance.  I see the choice of output tubes on OTL amps is limited for good reason.  Heck, the 6BL7 even has fairly low plate resistance for a typical triode too.

 

I think the base qualities of the 6BL7 are really good, but asking them to perform output tube duties in this circuit is asking too much of them it seems.  On an interesting note I will miss the fact that the amp is utterly dead silent with these tubes in the output stage, there is zero background noise.  You cannot tell it is even on until music starts playing.  It's going to take me a few days to get used to the wonky noises the 5998 makes again.  I'd love to hear an affordable transformer coupled amp based around the 6BL7 someday.

 

Also, they didn't blow up!  tongue_smile.gif  I'm guessing they are at or over their ratings here but the tubes have been very well behaved while I was experimenting.

 

On a somewhat unrelated note, Glenn do you think the 5687 would make a good 6SN7 substitute?  I see people selling adapters for this on eBay and the specs on the tube seem quite suitable for the most part.

A completely black and dead silent background is so inviting. Inside my own room, the few times I have experienced my rig leaning that way, things quickly turn to "Not so fast.." It seems, I'm always having to give up something. And it becomes apparent right on the heels of this short lived moment of magic.

It's a Brätwurst disguised as a 596.

 

The 596 is made by United Electronics and is a rectifier.

where have you been this last year? Read Mister! :p

And before you ask, no sorry I shipped out 24 596 tubes already and have none left, maybe in a few months ;-)

You really do have a Bratwürst fixation, don't you cool.gif

Silent One, a Decware, Glenn amp, Bratwürst & Beer meet in Cali would convince me to come over for sure.

Do you think airport customs would mind me bringing dozens of tubes for you guys? Where's Clayton's back pack? ;)

 

I'm hungry now!
