So, I've got some time on my hands and a little extra cash. I'm going to look into building a Sunn Model -t clone, since you can't find one for under 2 grand these days. (original version, not the re-issue) I'm an electrician and I've got quite a bit of electrical theory understanding and I can solder well, I've just never built an amp before and was wondering if the experienced guys out there have any input on what I need to know before i jump into this. The schematic is here---> http://www.ideologic.org/news/view/sunn_o_1973_model_t_schematic

thanks all.

Watch what you do in regards to grounding although this shouldn't be an issue for you as you are professional. Those tube amps can shock you even after they have been off for a few minutes. I'm sure you know all that, just be careful.

This will be a difficult and expensive build and, IMHO, it is foolhardy to attempt it as a first build. I highly recommend lots of research on tube circuits, lead dress, and electronics in general and starting with a simple amp, like a 5C1 Champ or something.

How is your electronics theory knowledge? Being familiar with electrical theory and being a professional electrician (what kind of electrician?) doesn't have as much bearing on the electronics side of things as people seem to think it does.

Ok, I was hoping that wasn't the case. Any recommendations on books to read or sites to scour to get me started? I really want to build this thing and learn to build amps in general. If it takes a long time, so be it.

It won't take as long as you might think if you genuinely want to learn and have access to some good resources and knowledge bases and, of course, practice and experiment yourself. Here are some sites that I remember off the top of my head.

This is probably a good place to start.
https://www.ultimate-guitar.com/forum/showthread.php?t=1223425

This one is an online textbook that covers a very wide gamut of info. Each volume is available for download as PDFs and there's even an android app (and probably Apple as well).
http://www.allaboutcircuits.com/

This one is a great resource for tube amp theory and design.
http://www.valvewizard.co.uk/

This one has lots of info but focuses mainly on effects, but there is also some good general and amp info there.
http://www.geofex.com/

That's all I can think of right now. Should keep you busy for a while though.

why not start on something easier for your first build? that's quite a big amp!

I assume you fully understand about the hazards of working with electricity

The Tube Amp Book by Aspen Pittman is amazing and a blast to read (loadsa schematics too, comes with a CD).

The Tube Amp book by Dave Hunter is also an amazing book, I'd say those two are a must, they cover just about everything you need to build your first tube amp.
