New DiVision Vacuum Tube Direct Box from Lightning Boy Audio

[TalkBass]

Lightning Boy Audio introduces the DiVision. This is a limited edition vacuum tube direct box. It features a tiny 6DS4 nuvistor vacuum tube running at 230V for big tube tone and headroom in a little box. So little in fact, it weighs just under 1 pound.

The DiVision is powered by a standard 9V pedal adapter and boosts it internally to deliver the full tube sound you'd expect from the more common mains powered tube direct boxes. The output is mic level and 200 Ohms impedance, derived from the onboard output transformer, a Lightning Boy Audio MC15. The DiVision offers up to 11dB of clean boost with a rock bottom noise floor. It has an active shelving EQ, labeled "Vision," which uses the tube to produce a treble boost of up to 6dB, shouldered at 10kHz. With the Vision knob fully turned down, the DiVision presents a flat response from 10Hz-22kHz with 0.2% THD+N. The tube amplifier stage operates as class A and is single-ended.

Only 68 DiVision's will be produced and sold direct from www.lightningboyaudio.com for $329 USD.

Why make a limited edition DI box? Is there really a market for that?

Because Nuvistor tubes are no longer made and I had 68 of them. And yes, there is clearly a market for this since people have been buying them.

Gotcha!

Interesting! Can you put a number to the 'ultra low noise' spec? ( I couldn't find it on the website...) Thanks!

I have the ability. Finding the time is a different story. I've been trying to get to it. Hopefully this week I can.

Noise Floor = -99dB RMS A weighted after the DiVision has been powered on for at least 10 minutes. -95dB Peak with no weighting.

Awesome! thanks for the data

I see them F/S on Etsy but low stock. Is there a substitute or upgrade for the tube?

It's a shame they don't make that tube anymore. Damn transistors. I did some looking into the Nuvistor and found it was used in some of the finest audiophile gear that I've had the opportunity to listen to over the years. I can see why you decided to build your DI around this particular tube. I'd like to hear that pedal and the only way that's likely to happen is to order one. If there are any left.

There's more left and I have a 30 day return policy.

There are a few variants that are basically the same: 6DS4, 6CW4, 7895, 6S52N-V.

What is the input impedance?
