"Color" Tube Pre-amp for Solid State Amps: Power Supply #1

In this video we start laying out and wiring up the power supply section of the amplifier. This will be followed by part #2 to finish this up!
This series is about building a tube pre-amplifier for use with any "overly sterile" sounding solid state amplifier. This device introduces the warmth and second order harmonics people associate with tube gear, in a controllable and consistent manner. The builder can add multiple sources and other options, we are building a basic version to showcase what it can do. At the end of the series we will be doing a complete technical and subjective test of the unit.
Here is Matt's website explaining the design of this amp:

"I'm more of a star ground person" - you could print that on a T-shirt 👍

If you’re ever looking for only those strain-relief parts for a captive power cable, they have the head-scratching name of “cable gland” at most suppliers.

Bought my tranny online for $16.50. A few weeks later my buddy asked me to build him one and the price had gone up to $61.80!

There is a guy here on You Tube that had built a pre-amp like this, but using a 6SN7 tube. He also built a tube based power supply for it, but he added an OD3 regulator tube. Now, while I understand the reasoning for this to create a more stable DC supply, I have read that these regulator tubes can be very noisy. For the most part, I USUALLY don't see them used in commercial tube amplifier designs, but I have seen at least one amp made by Grommes that used a regulator tube for the bias supply. Not sure if you are interested in building another one of these with a tube regulator and do some tests on it to see how much noise the regulator tube adds to the signal.

There really is no point in regulating the DC in a design like this.

@@SkunkieDesignsElectronics I didn't think so as I have seen many amplifier designs and only a handful (if that many) are using a regulator tube. I know at least two designs were by Grommes. But when I saw the recent design on You Tube, it had me scratching my head. I mean the tube looks cool and would make a sensational power indicator, but I heard they can introduce noise in a circuit as well.

I live in Denmark and we have 240v. What transformer can i use instead and does any other parts have to be different then? Thanks in advance.

@SkunkieDesignsElectronics 10 ай бұрын

A 300 series hammond transformer is used and no other parts need to be changed.
