I've been into digital electronics for years and because I like computers - I'm a computer tech. I've built digital parametric EQ kits, Haffler amp kit, rewired guitars and built computers over the years. Wave soldered boards, hand soldered components, etched my own boards, and even wire wrapped ckt boards (Ugg!) for a time.
I'm also a musician (isn't everyone?) and thought I'd like to take on a new challenge. Tubes have always interested me and I decided I'd take the plunge. I realize they are completely different than digital. But, like learning any instrument, you have to have one to learn how to play it.
I got an ODS #183 from Nik and started following the layout he provides. I've used the pictures of builds at TAG to do a proper layout.
Kind of disappointed that he doesn't use/supply Switchcraft jacks, but we'll see how long these plastic ones last. I suppose I could have sourced it all out? Maybe the next one?
I've yet to order the PT, OT, & choke. It's heavy enough without having that to contend with just yet and there's plenty to assemble beforehand.
Unpackaged and I counted up the parts. I made copies of each layout (Talbany's and Niks) and had Costco photo blow them up to 12x18 color photos for $3 each. Very good for seeing where stuff goes! Clear and precise and in color!
Some observations:
First time out I can see there would be a better way to 'assemble' the parts using an external "jig" to hold and preinstall components/wires to the switches and pots, even some of the sockets. Cramped quarters otherwise. It would be a simple task to remove from the jig and install.
Nik offers no 'technical' help on the cheapo buy. Meh, there's plenty of knowledge here to help the neophyte. However, I've yet to read where the different size wires come into play. Logically, the larger gauges for the higher voltages and the smaller for the small signal relays etc. There is one solid core wire I'm taking to be for grounding purposes? Obviously, the shielded wire for signal path.
I checked Tabany's very helpful post here:

against Niks here:

and realized that his is a little bit 'different' than Niks. I like the idea of the Convenience outlet, but am curious as to the 50/100 switch vs having the impedance selector?
Two different things, but I'm wondering, unless you are stacking speakers in different configurations all the time, how often does one need an impedance selector? Also, why would you want to go to half power? Wouldn't the master volume determine overall volume? 50W is plenty loud, but 100W isn't 2X as loud.
Sorry for the ignorance here, but the question came up as to what is the 'difference' and why?
Another head scratcher is I haven't found a clear close up of the power tube socket wiring. Though I've been searching, I could have missed it?
My goal is to document my build with all the warts and successes. I hope I can do as good a job as the giants that roamed the Earth/ground before me.
Please feel free to add suggestions and advice as you feel needed. Especially if you notice any errors!
