Making a 12AX7 substitute from two subminiature 6247 triodes

November 6th, 2015 by

I have a handful of these 6247WA subminiature triode tubes that I bought way back when I was getting interested in tube electronics. They were very cheap, and thus good for experimenting with when I didn’t have a clue what I was doing. Now that I’ve graduated to more common and more expensive tubes, I’m…

Custom 1×8 combo tube amp: build log #3, finished!

May 26th, 2015 by

I’ve started putting together the electrical parts of the amp. This is where the real fun begins! This log is going to be rather picture-heavy if I can help it, with explanations placed where pictures are worth too few words. First comes the power input section.

This turned out to be exactly on top of where the old power transformer was mounted. The hole the old transformer lived…

I’m not so good at this whole “consistent project log” thing, am I? In any case, I’ve made lots of progress since my last check in (the introduction, hah)! The display board is complete, controls are hooked up and working, and TMOOS is quite functional. It’s able to run standalone from a battery and is…
