New vacuum tube

[gareth magennis]

Korg are making a dual triode low voltage tube.

Wonder if it is any good.

Actually, that's old news. They announced its availability about a year
ago. And the radio in my 1957 Ford had low voltage tubes (and no
vibrator) in it.

It is reviewed in last months AudioXPress.

The idea is kind of cool, but it doesn't look to be actually useful.
The curves are very weird, and it draws too much grid current to be
interesting for microphones.

And so do a few pre-amps that have been around for years. Generally
sound quality is secondary to simply advertising it is "tubed" :-(

That's not a low-voltage tube. It's a standard tube operated with a low
plate voltage to make it sound bad.

If you want some to play with:

And Vox are using it in an amp:

So, $50 for something with very low mu and hardly any current drive capability?
That seems kind of much to me.

A lot more info here, including links to the datasheet, and two projects
with pcb's - a buffer and a headphone amp - using the Korg Nutube 6P1.
I'm not affiliated, just interested.

I should have added things do get much cheaper when production stops
because of poor demand and the remaining units are dumped.
Then they sometimes get much dearer again if nostalgia kicks in and
there is a demand for existing units.
What course any particular item will take is usually hard to predict.

Might 'sound good' for an electric guitar. but if your objective is
'pure' sound, or sound modified only by what processes you have
consciously applied, then a tube/valve and (and possible associated
transformer) may also sound like ****e.

..... but they'll always sound fantastic is you back-light them with LEDs.

Purity is an illusion. Accuracy, however...

It's clear that this device is designed as a processing element for guitar
and other musical production needed.

It's not clear whether it actually sounds like a conventional tube in that
application; the weird curves do not look much like those of a 12AX7.

It's definitely not useful as a general-purpose neutral-sounding gain device
(which the 12AX7 is if you treat it well).

Ah, a superheterodyne radio tube!!
So, who else was clever to bridge the tube radio on/off switch with a diode, enough to keep tube filaments warm for instant on sound!?
