Crazy tube circuits Venus 2025

With box and power adapter.

While the classic masterpiece that inspired Venus originally shipped with an ECC83 (12AX7) dual triode tube, users looking for a smoother, cleaner sound replaced the tube with a lower gain/higher headroom variant like ECC81 (12AT7) or ECC82 (12AU7). With that in mind, we selected an ECC832 tube as stock for Venus. This kind of oddball tube features half of an ECC83 and half of an ECC82. The tone is as close as possible to the original “tube sculpture” but with more clarity, string separation and a wider soundstage.

You can still substitute with all the "usual suspects" of dual triode tube types like ECC83/12AX7, 5751, ECC81/12AT7, 12AY7, ECC82/12AU7 for a different sonic flavor. Use the bias knob to set the tube bias/control the current passing through the tube cathodes. By adjusting this knob, you can find the sweet spot for different tube types used and/or set the texture of the overdrive / distortion: from gnarly, nasty and gated (counter-clockwise) to smooth and creamy (clockwise). The full clockwise setting of the bias knob has the cleanest sound for most tube types used.
