Pills taken. It's just that it gets on my nerves when the answers are clearly in the thread or on Google tongue.gif

I understand that..but sometimes its easier to ask..as thread is so long! and it only needs a simple answer..and i didnt even know it was a rectifier biggrin.gif how could i look that up in Google if i didnt even know that? On the pic i couldnt know it was a rectifier..i saw a big sexy tube only.and a cat...lolz tongue.gif

I am a computer specialist as hobby and built the most extreme watercooled pc's for myself and others...and sometimes i do get questions also that i think..geesh..check google people..its so easy...but when overthinkin it..i understand allthough it sometimes seems completely clear to me, to noobs it sounds like chinese..and in this situation i am the noob. biggrin.gif but believe me i am onthe overrun lane..driving in uberspeed..before no time i will be up to speed about all whats tubes and amps.. I only need time and u guys and girls from tube-universe to guide me.. biggrin.gif
friends again? wink.gif

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.

 

The 5687 looks like a good sub for the 6SN7 the curves look good how it sounds I have no idea. I can make you a adapter if you want?

Actually the 6BL7 wasn't run to hard it only had 120 volts across it so it's current wasn't that high.  If you had 300 to 600 ohm headphones

your test would have come out different. After I build the next one of these amps I will try them with the HD655s and HD800s   300 ohm.

Also you can try the 6BX7 almost the same as a 6BL7 but with a gain of 10 instead of 16 also can be gotten for cheep.

    The 6BL7 sounds fantastic in a transformer output amp in push pull

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?

She is a spry 8!  Clean living and lots of catnip....wink.gif

 

Sorry though...No loaner cat's are currently available. I don't need the payback!

Thanks SO. The mighty 596 is a sweet piece of glass. I had to drive over 450 miles yesterday and I almost didn't go to bed the sound was so sweet....biggrin.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!

hmmm...checking the frequent flyer points for the freebie to Cali.......We may have to import Brats to Cali, not sure if they have the real ones there.

We have bears here...They take the bird feeders down if we do not take them in at night. Wolves too, but more Coyotes. Lot's of deer....We have about 8 inches of snow on the ground now so Winter is here until late April. Time to wax up the CC Ski's!

post #1423 of 9384

I just received a bunch of adapters from Glenn.  I cannot tell you how well built these are.  I can only imagine when one of his amps feels like, let alone sounds like.

 

Thanks Glenn.

post #1424 of 9384

My 596 adapter is terrific. Firm fit in the amp and the top connectors are solid without being too tight. Glenn builds them right!

6 pairs already, I think you need counselling..........

It's the first step...........

So you have time to evaluate the 596 and tell us what you think of it!

We expect a report by Sunday night, or else.................the bears...............
