What head amps are people using these days that use the 6AS7/6080 and variants??? I have not been on the board in a long time and I am out of the loop. I am still using my old circa 2003 toaster style Singlepower Supra that was modded to use the 6AS7. After many years ( since 2008) I have yet to replace the original RCA black plate 6AS7G's.

You may be right, but the grey plastic end looks a bit different to my Sylvania (black plastic). Also note the strange fabric between metal base and glass, haven't seen that before.

That is common with 6080WC tubes.

Pretty much all OTL's use them.  I'd have to dig for the link in the crack thread, but there's a very detailed technical article that explains why this family of tubes is pretty much the only suitable option when designing cathode follower headphone amps.  In a nutshell, its the only viable way to get the output impedance down (low enough for high impedance cans anyways) without the use of transformers.  

 

The usual suspects running this power tube are the bottlehead crack, woo 2, woo 3, darkvoice/lafigaro amps, singlepowers, etc.

 

Edit - found the link to the article:  http://www.hificollective.co.uk/pdf/otl_head.pdf

Have anyone tried the Thomson 6080WA (likely to be French production) ?

 

And what about Philips 6080, are they all Mullard made (and what is a fair price for those) ?

 

I'm also looking for a quad of Bendix. After a dozen emails, I found a "decent stock" of graphite 6080, for 175 USD each.

Yep gents, you read right :blink:

I'm waiting for vacuumtubes to reply, but if you have another clue to find those, I take it.

Greetings from Finland

 

I managed to build DIY amp that uses 2 6SN7 and 2 6AS7 or 6080. And so i have joined to tube rollers of these monsters. It seems that with these tubes i can drive easily even more difficult headphones. Driver tubes in this photo are Sylvania 6SN7GTA.

 

Only tubes i have yet are these Philips ECG 6080WC USA. I guess that these are made in old sylvania factory.

Hope i get soon Russian 6N13S '73 svetlanas and can try to listen differences between these. So far i have been very happy with 6080WC's, but i need to read more this thread and enjoy my new amp.:dt880smile:

Nice looking amp.

 

Are your drivers Sylvania?

50's-60's Svetlana are supposed to be even better.

 

Happy Listening

What a nice build, well executed. smily_headphones1.gif
You will find a ton of great info in this thread and also the various Woo Audio and little dot threads that have amps that use the same tubes as yours.
There are also a couple monster 6SN7 threads that are invaluable.

Drivers in photo are Sylvania 6SN7GTA's. I have some pairs of 6SN7's to compare.

 

May i ask what kind of electricity consumption does factory made 6AS7 amps have? And how hot do they get after couple hours of usage? Mine gets pretty hot, but still not hand burning and consumption is 88w.

post #973 of 3825

I haven't checked the power consumption but they do run hot.

 

If your drivers plate voltage is below 250V you can use 6SL7's too.

If your transformer can handle 1A heater current for each driver you can try the ECC32.

 

Be aware tube addiction is just round the corner.

I have some 6SL7's too and they work very good. ECC32 tubes seems to be out of my budget. Perhaps one day i'll buy pair of RCA 6AS7's.

 

Received today pair 6N13S tubes. One tube has weird hum problem. It stops when i touch tube in the right spot on the glass. Hum follows to other channel if i change tubes, so problem is not with amplifier itself. Hope this hum stops after some burn-in.

 

Tube rolling already grabbed me in with little dot mk2.

 

Edit: 6N13S hum stopped after couple warm-ups... and came back too!

I recently acquired a Woo WA3 so I have been lurking in this thread for awhile; thank you to all who have contributed as I have benefited from your insight and experience.

 

My latest 6AS7G is somewhat of a mystery to me; I was hoping someone here could shed some light on it. This top getter, black plate GE 6AS7G has a few unusual distinctions: the box is marked Canadian General Electric, it has copper grid rods and a clear glass top much like my JAN Chatham 6AS7G, and the base is marked with the usual GE logo, but in orangish ink with a 'PQ' in front of it (I assume this stands for premium quality as it is used elsewhere). The only other markings I can find are a 'C' on the glass itself. 

 

I haven't had a chance to give it a listen yet, but I will gladly post my impressions for what they're worth when I've had time to check it out, as well as a picture of this tube.
