If you're an audiophile who likes to
"roll tubes" in your amplifiers and
preamps please consider this regarding
your 9 pin audio tubes:
If
you bend the tube pins installing or
removing the tubes or simply install
and remove tubes with bent pins, you
are spreading out the individual pin
sockets in the tube sockets of the
amplifier.
As a result of this, the tension that
the pin socket grabs the pin with is
lowered in some cases to the point of
zero tension.
At zero tension the pin would just
fall out of the socket if the amp were
turned upside-down... When this
happens many don't realize it because
there are 9 pins so unless all 9 were
loose it would be hard to know.
The only way to test tube pin socket
tension is by taking a blown 9 pin tube
and cutting off all but one tube pin.
You can then use this tube with only one
pin to test the tension of each hole in
the tube socket one at a time.
When you look at what people spend on
cables, connectors, jacks, wire, volume
controls and so on, these same people
would be mortified if a jack were loose
and yet a tube pin is no different.
Having dirty tube sockets with pins that
have low tension will have a LARGER
affect on the sound quality of your
amplifier than any single component of
the amp like its capacitors, resistors,
jacks, transformers, wire, etc.
To KEEP YOUR GEAR
SOUNDING ITS BEST by keeping
your tube pins STRAIGHT - you need one
of these!
We designed and
machined these here in the USA.
