Nixie tube amplifier project - unfinished - help!


Hello!

My name is Kate and I'm in the Denver area. I was directed to this group by Karl at The Music Room. 

My late husband, Adam, was an electrical engineer and audiophile. As a passion project, he was building his own nixie tube amplifier for our stereo system. But, almost two years ago, he had a heart attack and died suddenly before he was able to finish the project. It was very near completion; I saw him install the tubes, power it on and watched the tubes glow - it worked! He sourced all of the parts himself and designed it in CAD. I have all of the parts and engineering diagrams, but they might as well be in Chinese to me. There was some final tinkering and assembly that he needed to do, along with building a case to house it.

I was wondering if anyone might be interested in trying to finish a project like this? I am getting ready to move out of my house at the end of July and need to do something with the amplifier - but the thought of just throwing it in the garbage kills me. It's also insanely heavy (transformers, I think), so it would have to go to someone locally.

Let me know if you have any interest or want more information. You can email me about this as well at [email protected]

Thanks!

Kate

Check to see if you can find 6V6 anywhere on the 7P tube.
@kjmelvin   I run a small tube amp manufacturing company called Atma-Sphere. If you want, send me a photo to my email address. You can find that on the contact page of our website www.atma-sphere.com

Maybe we can get to the bottom of this. If you have the schematic diagrams and parts, I'm sure it would not be hard to sort this out. I have to admit I'm curious what the VFD tube is doing in a project like this.
@atmasphere Sent you an email. Thanks!
