6C33C and Aleph, Aleph-X topologies.

Gyuri · 8th May 2011, 10:19 AM

Ever since I saw my friend Chris OTL amps, I think I need to make amplifier with 6C33C.
But I can not decide which one to do.
Let this be the kind of Tim Mellow, or the kind of Graaf GM20?
Maybe something else?
Tonight I saw a dream.
Would the Aleph topologies feasible with this excellent tube?
Of course, without any FET and output transformer.
I hope the idea is not completely hopeless.
But you do not expect more from me, because I've mentioned earlier, so I know little about electronics, such as the hen to ABC.
I know that Papa does not understand the tubes, but there are experts on it outside. Now I was deliberate insolence, as I always.

Papa is engineer , so he certainly understand tubes , but they obviously aren't type of (commercial ) sand for his sand box

anyway - if you want any type of xformerless output stage with Babushka , you still need to use several in parallel , to have adequately low output impedance ( still heavily dependent of negative feedback) . if you're willing to take that ( necessary) approach , then you can choose between several types of possible output topologies

then - say - J2 topology - long time known in tube world , is interesting .

edit : if you're dreamer enough - just look around in tube forum , for Atmasphere threads . Da Man itself is around .

that topology is easily converted to SUSY

Oh yeah, easy for you but not for me.

We could not possibly a bit more specific?

Zen Mod · 8th May 2011, 11:16 AM

yes we can

but I'm too lazy to search for schematic of Atmasphere

At the moment I feel the
Tim Mellows' amp I could realize on my own merits.
Maybe it would not be bad at first.

OTL designed by Tim Mellow with 4 6C33C?

Zen Mod · 8th May 2011, 11:48 AM

this one ?

not symmetrical

Sometimes it seems you did not understand the joke?

naah
