6SN7 Tube Addicts

They draw 1.4Amps compared to 0.6Amps of a 6SN7.
In a typical 6SN7 amp they will damage the transformer.
 
Glenn's OTL can handle the 1.4Amp easily.
They are worth trying for sure.

 
Given my stock of 6SN7s, ECC32s, ECC33s and 6F8Gs, would this tube be superior to those in Glenn's OTL?

The BL63 sound signature is unique. My vocabulary limit my words in describing it. But from what other users have said in the ECBA thread, the BL63 is one of the top 6sn7 if your amp can support it. I have lended a pair to dBel84 to try on the Cavalli LG and maybe he can chime in and described it sound.

David I think it's worth a try, you only need one.
 
I have not tried it as my transformer might be on the limit and I don't want to push it.
 
I have read mixed comments about it, some people mentioned a weak low end, it's all about system synergy and personal preferences.

I think it is all circuit dependent.  I have seen people say the ECC33 is bass weak and it gave me the best bass I've ever heard on headphones while I was demoing the tube.  The words "maybe this is too much bass" almost left my lips at one point and I'm pretty sure nobody listening to a K701 has ever said such a thing before.

Been wanting to find one of my own actually but the prices are just absurd and not worth it to me sadly enough.  I can't help but be curious what it would do on the LCD's though.  Probably provide a good head massage.

I still haven't tried ECC32 driver tubes yet. That's a shame...

This was a television tube replacement for the 5U4.  A little more rugged with a little better current at high voltages.  It is a good tube--not used very often.  Great replacement in a power amp.

Xcalibur it's true a lot depends on the circuit.

The 5U4 is a full wave rectifier.
 
The ECC32 is a double triode similar to a 6SN7 but with a higher heater current 0.9Amp and higher gain.
 
But I agree the ECC32 is a wonderful tube.

Thanks for the tip George.
 
Just as well it ships to US only!
 
I bet it revitalises body and mind!

Are you going to try?
