The TOWARIšč is basically a derivation from Triode Dicks "Everymen's
Single Ended".
I mainly did this amp, because I had fitting
output trannies lying around,
the 6C4C tube's relatively cheap (esp.
the very reliable russian NOS/NIB versions)
and I always wanted to do a
SE to prove the underlying legends with this kind of
amp.
Dick did this amp according to the old tube manuals (Bias,
Voltages,
Currents etc.).
After I read an article concerning a conservatively
rated 2A3 amp (Sorry, I can't find this article.
It was from an
american DIY'er, following the tips of a japanese tube guru),
I decided
to rate my 6b4g amp as stated out in this article and used a B+ of 275V
only.
I can assure you that it works.
You'll get only about 2.5 to 3 Watts per channel out of this
design.
If you have speakers with at least 93db sensitivity it's
sufficient enough
for a 25qm room if you won't listen
to techno in full blast.
Always when friends are visiting me, I play some (loud) music
on the
6C4C.
In almost every case they advice me after a short time to turn
the volume down, because it's much to loud.
When I'm telling them, that
they've listened to 2x 3 Watts in the last minutes,
I
always get
this special look, saying "What's this idiot telling me. He
wants to take the mick out of me."
How does it sound ? Very good - not more, not less. Please
don't expect
to get "audiophile" phrases from me.
The Towarišč
is a very good sounding
amp with the typical acoustic properties of a single ended amp.
Like in all my designs I used normal components. All R's are
standard
2W MO Types from Reichelt.
The C's are MKP Types and the Cathode R's
Bypass Electrolytics are bipolar types.
The output trannies are from
Welter.
The main trannie is from HB Ampdesign and I use two
trannies for 5U4G Heating from Reichelt.
You can find their
Web Sites at the audio/diy-linkz.
There are no Hi-End Voodoo devices in there.
I will
not deny
that the amp may sound better with this hi-end, voodoo devices.
For me
it's sounding good with the normal components.
And this components
didn't blast my budget.
