#1 New Transcendent pre-amp

Post by Ray P »

Bruce Rozenblit has just released a new preamp kit, the Slider.

I thought I would mention it because it has a novel variable gain feature. That's variable gain, not variable attenuation (it has a conventional volume control too), -3dB to +20dB.

It occurred to me that variable gain might be quite neat in a MoFo front end context.

Oh, it has a built in phono stage too.
Sorry, I couldn't resist!

The artical is distorted on my phone so could not read it all but I've built a variable gain stage with the pot on the cathode, it worked well as i remember.
The tube manual is quite like a telephone book. The number of it perfect. It is useful to make it possible to speak with a girl. But we can't see her beautiful face from the telephone number

Abut half of the distortion spike at 1 kHz is residual from the signal generator. This measures about 0.2%.
Well he should get a better generator then.
