But not the other way around I suppose?

Btw have you heard the T90? I'm thinking of selling my T70 as I like the T90 I got a lot more. Any thoughts?

I have not heard the T90 maybe at the next RMAF. My feeling if the T90 sounds more like the DT990 which I have tried and returned it may not be my best choice. I did brought the DT860 underdog and it far better than the DT990. It has strong very clear dynamic bass, clear mid-range and bright but smooth highs. I am impressed with the DT860 and still have my T70 with great outside sound insulation. The Beyer's T series are very conformable and more so than my DT860 which seems to use the same headband on some of the Ultrasone models.

Glenn, so the cat is out of the bag? Have you already hooked the 6336 amp in working order? Any early impression?

I Have been experimenting with the 6336 I haven't really said that I was building anyone a amp.
And haven't tried it with the BL63 yet.
The amp will work fine with one GZ37 don't really need two in parallel I have been running a stereo
6336 amp with one 3DG4 rectifier and works fine.  I will try it with one GZ37 tomorrow morning.
 
OK the cat is out I am building Neogeo333 a 6336 driven by a BL63 amp with a GZ37 rectifier I guess it don't matter.
 
So far the 6336 sounds fantastic it destroys the 6AS7 and all it's variants a amp with this tube has enough power
to blow headphones out if you are not careful. The amp will never distort it just gets louder and louder until the head phone
starts popping on the bass like a over powered speaker.
I still have to spec it into various dummy loads and check distortion and power output on equipment.
The amp will also be able to take 6AS7 tubes if you want.

First day at the office after having spent 3 days with my gear at home. I miss my amps

New Experimental Amplifier
 
My initial goal was to make a amplifier that would sound good with
the lowest cost tubes. You can still get 6SN7s for $1.00 so this is the
amp with all 6SN7s 8 for outputs and one for driver + one 3DG4 rectifier.
Total Cost for tubeing was $9.00 for 6SN7s and $1.00 for NOS 3DG4 from ESRC.

 
 

 
This is the same Amplifier Useing 6BL7s as outputs
More power less gain and better sound to me
These are $4.00 each
 

 

 
Same Amplifier with 6AS7s for outputs
Anyone that has one of my OTLs know what this sounds like
 

 
To my suprize I tried 6336 for outpute because the power supply
can handle these current hogs.
These tubes walk all over 6AS7s power and bass is great
 

 
This is with a GZ37 rectifier
 

 
I hadent notised any diference in sound between the
3DG4 @ $1.00 and the GZ37 @ $100.00 so I recomend
the 3DG4 but it doesn"t look as good.

 

[Ultrainferno]

Looking good Glenn! Now I want a new amp that can take 6AS7G and 6336

So even with an adapter an actual 6as7G amp won't be able to take the 6336, right?

I've always liked the 6336. How big is the power supply you're working with?

 

[2359glenn]

The power / mains transformer has to deliver at least 6.3 volts @ 10 amps for these power hungry tubes.
