Hi Bas
No comparison, I love the EL84 in any shape or form but the OTL slays it. IMHO (self protection from those who protest such a statement)
Reinhard, pretty much told the story (especially the bass!- tuneful with lots of slam), add to that great clarity and a neutral character and you have a winner.
It sounds even better after its been on for about 8 - 10 hours!
I would like to see a higher power version, ~ 20W.

How does it compare with say an EL84 single ended amp?

A little inspirational reading about SE otl´s:

As I told you the cathode follower is working on an inductor.
Each C19 has an additional cathode resistor of 5 Ohmsfor better
current sharing. The plates are sitting at nearly 100 Volts and the grids are at -12 Volts (Three teminal reg)
Don´t know the bias current but I thnk it is near 400 ma to get
1.5 Watt at 8 Ohms.

Dear All,
Howabout the circuit in this:-

Does ant of you tried the OTL one ?
CHOW

Hello,
I'm very interested in se OTL.
What about KTR circuit?(about " super Totem circuit" I saw in LED magazine.They use as preamplifier, the output impedence is about 5 times lewer than SRPP.
In the next days I'll scan the circuits and I can mail if you are interested.
Another thing :Morgan Lundberg , the audio friend with the link of 519 OTL is very friendly and I think that can help us.
Sorry for my poor english.
Ciao

Hello,
what is LED Magazine?
Yes I´m interested, mail to
in.audio@gmx.de
What is a super totem and why is the impedance 5 * lower?
