Nixie tube amplifier project - unfinished - help!


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]




Nixie tubes do not amplify. They display numbers and are the old school version of what was around before LEDs were used to display numbers (like in old digital alarm clocks). So a nixie tube amplifier doesn't seem to be a thing- could it be some other kind of tube?
@atmasphere : You are correct!  Its got to be some other tube type! I am curious and hope the OP will respond!

Hi all! 

I'm sorry that I don't understand this better. I am absolutely certain that this involves Nixie tubes. I don't see a way to post photos in this forum or else I would post some pictures of the project and the diagrams. 

@roberjerman did you send me an email? I don't see anything in my gmail. I logged into Hangouts and also didn't see anything in there. 

Thanks for your responses!
