If you read the post:

then you know that I am happily employ an interesting 65dB-gain, 7788-7721 two stages phonocorrector designed and build with air capacitors. A few days ago when I eventually got my SPU Mono replacement I decided to finalize the design and find a correct screen supply for the input penthod.  More about it at:

The scenario is very simple: a VR isolation tube with a driving resistor and small pre-screen stopper. However what I would like would be to get rid of a capacitor before the pre-screen resistor. There is an opinion that the nature of the gas regulators create a noise but I wonder if exist out there any ultra low noise gas 75V-105V regulators that would be able to drive the screen without any caps?

I pulled out of my storage a collection of my gas tubes and so far I use Philips 85A2. (Data is here) The noise-wise this tube it looks like is in the realm of any other VR-75, VR-105 tubes. So, are my dreams about the noise-free gas tubes an utopia?
