I think it's time to give up cogs and sprockets, and go into full time synth building!

Cheers!  :o)

Moog?) method of matching transistor pairs for the ladder. The method I chose was one Ian Fritz outlined in a relatively popular article. I apologize for no link but it can be found in the common search engines. It made the matching task quite a bit easier. The panel was a 2U dotcom blank which I engraved with a milling machine. The font didn't come out as legible as I had hoped but it is suitable for my use.

It is a Random Gates module from Yves and again, a bridechamber kit except for the 1U space MU panel which is from Big Blue Wave. Clearly the best panel job of all three by far. There is a bad LED in slot #4 so no output occurs there. I need to get another LED from Scott I guess.

I have been building only for a short time after having taken a break from EM for a few decades so here is a good chance to get a real laugh at my expense. My craftsmanship will have to improve. I realize this is elementary to most here but I trust you will afford me a bit of pride in these easy builds.

I had many "Ah-Ha!" moments when trying to grasp the component characteristics and even supply filtering fundementals. Great fun.
