Marblewood

We got some unseasonably nice weather here today. Clear blue skies and about 72° outside. This meant I got some time in my shop to move projects forward.

I haven’t talked about the new amp in a while so I thought I’d share current progress.

Remember when I said that you can’t always get what you want? Well, it turns out you can. At least in this case. Especially if you are willing to shift some priorities.

Lately I’ve been looking at a revised amplifier design based on the Marblewood project. The intent of the redesign effort is threefold. First, a different and more widely available rectifier tube. Second, an improved, if slightly more complicated, power supply design. And third, some potential improvement in the low frequency response. As it turns out, you can’t always get what you want. But also, two out of three ain’t bad.

There is something very satisfying about seeing a project really start coming together. I finally got some time today to start working on my 6V6 Marblewood amplifier project. It now looks like an amplifier instead of just a pile of boxes and parts.
