I’ve been pretty busy for the last month. But things are starting to move forward again. I’m still working on the project page for the Source Selector Unit and something new as well.

An Opportunity
As it turns out, there is a crew working on painting the exterior of my house today. Since I can’t work on many of my outdoor projects around the house, I thought I’d take the opportunity to get a little done on the source selector unit.
Continue readingCompleted Tube Assembly
I got some time today to finish out the vacuum tube assembly of the source selector unit.
Continue readingSignal Sections Fully Wired
Yesterday I was bottling mead but today I got a chance to wire up the buffers and tie in the coupling capacitors. This completes installation of all the signal chain components. All that’s left on the assembly is the final power supply wiring.
Continue readingSource Selector Chassis Wiring Complete
I had the opportunity today to sit down and finish up the wiring on the source selector unit chassis. It has been a productive week for this project. Now that the chassis is in good shape, I’m free to move on to the assembly and wiring of the vacuum tube circuits.
Continue readingSource Selector Chassis in One Piece
This morning after installing the selector switch and all its pigtails in the chassis, I decided to install the base plate. The chassis in now all in a single assembly.
Continue readingSelector Pigtails and Chassis Wiring
I made some progress today on the Source Selector Unit. The twelve twisted pairs are all soldered to the selector switch and I managed some chassis wiring as well.
Continue readingWiring in Technicolor
So what does one do when needing to keep twelve signal paths clearly separated and easily identified in a chassis? Actually the answer is remarkably simple.

I’ve been waiting for some wire I needed for twisted pairs and a Fender style fuse holder. I really like these fuse holders. I find them sturdy, good looking, and reliable. I have some cheaper ones but I reserve those for brassboards, quick projects, test equipment, and the like. While I’ve been waiting for my deliveries, I’ve been populating the chassis.

I’ve finally completed the finishing of the bubinga chassis. It has four coats of hand rubbed oil finish. It really makes the wood grain stand out.
Continue readingFirst Oil on the Chassis
Today I got the shop cleaned up and applied the first coat of oil to the bubinga chassis for the Source Selector Unit. (Still looking for naming suggestions, by the way.) The oil really brings out the grain. I think it will look even better than I thought it would.
Continue readingMetal Work and Policing Ground Loops
I took some time this afternoon to get the metal work completed (mostly) for the Source Selector Unit/Preamp. All the drilling is complete and everything is properly fit to the chassis. The only metal work left to do is four holes in the mounting brackets which need to be drilled and tapped. These four screws will hold the top plate in place and make swapping tubes easier.
Continue readingBack to that Metal Work
Well, eleven days since my last post and the cedar fence is done, the garden is in, a toilet has been replaced, and a new batch of black cherry cider is in the fermenter. So I decided it was time to get back to the metal for the source selector unit.
Continue readingChassis Metal
I’ve been working on a whole bunch of different projects this last week. But I managed to carve out a little time to get all the chassis metal for the source selector unit cut to size, fit to the chassis, and marked for drilling.
Continue readingAbout That Metal Work
I often get questions about how I design and construct my projects. One of the things I realized this morning, after receiving such a question, was that I really haven’t addressed my basic metal work and how I size all the aluminum parts I use for my chassis. So I thought I’d give a little insight into how I make these cuts and how I got to where I am today.
