Continue readingNo, I haven’t fallen off the face of the Earth. And I realize that people are waiting for the completion of the Source Selector Unit. I just got unexpectedly busy.
Continue readingIt took a while but the DC checkout is complete and I’m finally ready to finish assembly on the Source Selector Unit.
Continue readingThe resistors for which I’ve been waiting showed up this afternoon. Time to get back to work on the Source Selector Unit.
Continue readingWe’ve all done it or at least thought about it. It’s so easy. It’s really no big deal. It feels good. No one will ever know. Well, I’m here to tell you that eventually, you’ll regret it.

Continue readingAs I said before, I decided perform the DC testing of the tube assembly for the source Selector Unit in the clamping fixture. But just as I started testing, I ran into a little problem.
Continue readingI got some time today to finish out the vacuum tube assembly of the source selector unit.
Continue readingSo last night I posted about a mistake I made in wiring the latest project. And because of when and where I made that mistake, it took all afternoon to correct it.
Continue readingI can’t believe I did that! How could I have been so thick headed to make this kind of mistake?
Continue readingYesterday 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 readingBetween regular chores, gardening, and yard work today I managed to steal a little time to make some progress on the latest project. The gain stages for the source selector unit are essentially complete and I’ll begin working on the buffers as soon as I can.
Continue readingWhile I was preparing to begin assembly of the vacuum tube circuits for the Source Selector Unit, I was quickly going over the design and pulling components. And this is when I became aware of a little problem with the buffer circuit.
Continue readingI 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 readingThis 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.
