Dare I say, the 6V6GT can be a great sounding audio tube.
Especially for guitar amps, the 6V6 is my favorite tube. But there's no reason
it wouldn't sound great for audio and hifi use. Try it out and build something
with them. If you don't like it, you can always switch back to EL84 as the
conversion is pretty easy.

Yes it is. I am listening to a 6005W (6AQ5) based SE stereo amp that
I built as an experiment, and I really likt it. 6AQ5 is virtually the
same as 6V6.

Good, that means my hoard of 5AQ5's & 8AQ5'smay come in handy someday.

instead of the 6BQ5s that are in the original schematic(Eico 86) that I
am basing the design of my mono blocks on.This is my opinion and that is
all,but one of the nice things in my view about the 6V6 line of tubes is
that there are so many at such good prices that it is not hard to
collect a few Quads and switch them out according to the type of music
you are going to listen to.I am going to get as many matched quads as I
can find and listen to different music on all of them to find out what I
like best with which music.Just another thing that makes this fun.

I normally don't go around saying that I like 6V6's but since you
brought up the
subject, I do also. It doesnt have as much distortion as 6BQ5's. I
have a Hardon-Kardon
A300 which uses 7408's (a high class 6V6). I also have a 6V6 SE amp
which
I built, with the 6V6 hooked up as a triode and the output xformer
connected into the cathode. A cathode-follower amp. I think the 6V6 is
over looked because of its
low power and also because some folks think its a low power version of a
6L6. Not the best
HiFi tube around. Also the 6BQ5 is not really a smaller version of a
6V6. It replaced
the 6V6 in similiar amplifier circuits, but the 6V6's smaller cousin is
the 6AQ5.
Either way a couple of them is plenty to drive most speakers in the
average sized
living room. Let me know how you make out.

of these, one is on 24x7 for my pc system. I use audio glassic 6l6wgb
tubes, which work great in the Award 300, Citation V, and Fender Deluxe
amps from the '50s and '60s.

Aha... someone else who likes 'em :-) You may have seen a thread
where I am asking the question about which valve sounds best. I have
built a small SE 6AQ5 amp and want to do something bigger.
Sheesh... maybe I should just parallel a few 6AQ5's..... 4 per
channel, triode wired, would give me 8 watts SE... they'd need a 1.5k
output tranny... hmmmmmmmm
Mr. James C. Mcshane
suspect.
I'm a 6AQ5 fan also. It's a real bargain in power tubes too.

Hi 6V6 Guys,
If you want to try something a little differant , plug in a couple of
6K6's
in place of 6V6's. They have the same spec's voltage wise but are
pentodes instead of
those beam power jobs. They have a bit smoother sound and are direct
plug in's.
Regards,
Helm.
PS 6AQ5's and 6BQ5's are not 6V6's no matter what the RCA manual
says!!!!
PPS instead of trying to come up with a matched set of tubes...design
the circuit to balance
out the differances. Buying quad balanced tubes was started by the
makers of run of the mill amplifiers. Look up the original design of
the PtoP amps and see how any old tube can be placed (of the same type)
into the output stage and can be balanced.

Lot's of people say they are very similar.

I've never seen it claimed that 6BQ5's were the same as 6V6's!
Bill B.
The 6AQ5 is considered the same as the 6V6 with the exception that it
is a 7 pin mineature type as opposed to an octal. Anyway, the tubes are
excellent for 10 - 15 watt class A pushpull amps. I'd go with the 6V6
simply because there are manufacturers currently making it. With the
6AQ5, you are going to have to deal with NOS or good used. Many nice
amps use the 6V6, most notable are the Bogen DB10 and 110 series, the
Bell 2122 series and the Bell 3DT and older 3D Binaural as well as
several Fender guitar amps (do I hear Princeton and Champ?).
The only place I usually see the 6AQ5 is in television audio output
stages.

I would exercise a bit of caution here, if you intend to run them very
long, as the 6K6 has only a 8.5 watt maximum plate dissipation rating
vs. 12 for the 6V6. Also, at 250V (plate & screen voltage, SE
operation), the 6K6 data calls for -18 volts bias vs. -12.5 volts for
the 6V6. Similar differences exist for PP. Also, the 6K6 has a much
lower trandconductance (2300 vs. 4100 at same V and at their recommended
operating points). At the same 250V (Pl/Scr), the 6K6 data calls for 32
ma bias current vs. 45 for the 6V6. So, from the above values, in
cathode bias (SE), the 6V6 would require a cathode resistor of
12.5V/41ma = 305 ohms, while the 6K6 would require 18V/33ma = 545 ohms,
or, in fixed bias, an increase in bias voltage from -12.5V to -18V. For
a quickie listen, you could probably plug and play, in cathode bias, but
if making a permanent substitution, the bias should be changed as noted,
else the 6K6s will be run way beyond their maximum dissipation rating
with shortened tube life, probably drastically shortened. The 6F6, also
a pentode, is worth taking a look at and is a closer match to the 6V6,
ratingwise, having a plate diss rating of 11 watts and calling for -16.5
volts bias at the same plate/screen voltages. Unfortunately they cost
more nowdays than do 6K6s which are cheap as dirt.
