Just a note to anyone trying the Visseaux 6V6GT.
Unlike most (all?) other glass 6V6 GT’s, the Visseaux has a metal band around
the base, like a 6550. The metal band is connected to pin 1. Usually, on any
glass type 6V6GT, pin 1 is either absent or not connected on pin 1. The metal
band on the Visseaux is painted black, not shiny bright metal, so it isn’t
entirely obvious that it is metal.
In the typical Fender amplifier, pin 1 is used as a tie point for the control
grid, and the negative bias voltage is present.
If you use the Visseaux 6V6, this voltage will be present on the metal base of
the tube.
If your amp has the “bear-trap” type tube clamps, they will ground the metal
base of the tube and pin 1 in the socket, and rob the tube of all bias voltage.
To safely use the Visseaux 6V6 on the typical 6V6 guitar amp, you need to make
sure that pin 1 of the socket is not connected to anything other than ground,
*or* remove the tube clamps to make sure the base doesn’t accidently get
grounded.

which case you use unscew and remove them. In case you aren’t
familiar with the Visseaux, here is an excerpt from the 6V6GT shoot
out from Vacuum Tube Valley www.vacuumtube.com
Tube Valley said about this tube in the 6V6 shoot out in the most
recent issue of VTV:
metal-based 1951 tubes very hard. But the bias was rock-solid at 400
VDC, so I thought I’d push them to see what they could really take.
The bias was still rock-solid as high as 465 VDC (In a Fender Super
Reverb!), where I chickened-out, before they did. These are tough
little tubes! They sounded unbelievably good at 450 VDC and 30ma.
Nicely balanced, great detail, strong and punchy midrange, and
startling transients.
stout and punchy, forward sounding little tube. It evoked images of a
Mullard
EL-34 powered Marshall Super Lead 100. Rich, smooth, un-harsh, well
balanced, and
silky smooth. Full and creamy mids, with a polished stainless
steel-like
quality to the top. The mids were tighter, punchier, more aggressive,
more
assertive, and more focused than the RCAs. It’s one mean and nasty
tube!”

other guys seperately..but one guy asked how many of these tubes have
fried due to this problem.
sold to return three that I could tell got torched, and a light didn’t
come one until I got a note from another guy who noticed it and the
tubes were starting to run away at installation.
have bought them from me I’m sure are keyed into it.
dependable 6V6GT I have ever ever seen. Period. Nothing even comes
close.
the plates and 30 mils without even one hiccup. I have had a total of
6 defects….three of which were related to the one dealer who fried
three before we knew about the tube clamp. And most of the amps in
question don’t have that clamp in place. The ones who do…just
unscrew them.
