I saw the thread about the poor mans homemade little walter and had already been thinking of building my own amp. I was curious where one could find diagrams for the wiring and how much know how really is needed to build a few different types of point to point amps of various power ranges and variety of clean headroom or distortion.
Thanks

Think very carefully before you go down this road. I built one amp just to see how it works, just one. I wasn 't going to build any more. That was 20 amps ago.
If you are going to do this, then I suggest -
- you read up on safety precautions. You will be working with lethal voltages. Not only must you stick your fingers in a live amp, that amp also has to be safe enough for daily use.
- I'm assuming we are talking about tube amps. Learn something about how tubes work . Valve Wizard and AX84 have good free material .
- don't think it will be cheaper to build instead of buying, unless you find an old carcass with good transformers you can use.
- it's not just connecting wires. You have to worry about lead dress, oscillations, grounding schemes, and and and
- it probably won't work right the first time so be prepared to be patient and spend time searching for mistakes
- if you don 't know how to solder, learn. Buy a dirt box kit and learn on that instead of the expensive stuff.
Having said all that I love building amps. I have amps out the wing-wang.
I don't 'need' anymore but I keep building. In December I built a single-channel Deluxe Reverb which turned out just perfect. A couple of weeks ago I built this Vibro Champ Reverb. I still have a couple of things to do on the cab.

Yes tube amps, something "simple" so to say without any circuit boards.
I know how to solder and I am fairly knowledgable/understanding of voltages and how power loads work. Once I read through some instructions or guides, and maybe use ye olde Google to refresh my memory of certain things, I usually understand it pretty thoroughly.
I'm not sure exactly how you say it wouldn't be cheaper to build myself, in comparison to buying a new Little Walter twin head with external cabinet(s) that come in well over $3000,
Though I've not attempted pricing the parts to do such a build.

get this book by Tino Zottola:
[urlhttp://www.amazon.com/Building-Vacuum-Guitar-Amplifiers-Volume/dp/B004C7QAX8[/url]
It has plans for a few different amps, amongst them the Fender 5B6 circuit. Nearly identical to the non-stereo little Walter. There's not a lot of parts involved in that circuit, so the cost isn't too bad.
Have fun! |

Hi, Mark,
Would you be interested in a kit?
http://trinityamps.com/Product_Parts.htm has kits in Canada here, and I have no doubt you can find something closer to you there. I included the link because it has some good information on it. Enough that I was able to figure out that I didn't really want to build my own amp- I could get what I wanted by finding a good amp and building a fancy wood cabinet for it. But that's just me. I get my fill of electricity in my day job wiring houses, so I'd like to do something different at home. |

You are just looking at parts. Consider also the tools you need - are you drilling your chassis or buying one ready made? Are you building your own cab or buying one ready made? If you are building one do you already have access to a table saw , a router, and various sanders? Is your time worth anything in the equation? ( probably not). What are your expectations? Do you simply want a working amp or do you expect it to look like a Little Walter inside right away? They' ve built hundreds if not thousands of amps and unless you are a completely neurotic stickler your first amp will not look anything like a LW. They also buy transformers in quantity and not one at a time.
I'm not trying to discourage you - you should just know there is more to it than you think ans you should be ready for it . I studied it for two years before I built my first. It's a great hobby and I can build (and have built) any amp I want. It's very freeing to be independent of the industry. I 'm planning a single-channel brown Super with reverb. I don't know of anybody selling one of those.

You can build a LW 50w which is actually 30w amp for as little as $500. The 5b6 circuit is a great platform for guitar just add pedal board for reverb and gain pedals. Works well for steel guitar just add 15" speaker cabinet. Get Tino's book and get started.
There are many kits out there:
www.rjguitars.net
www.mojotone.com
www.triodestore.com
www.ceriatone.com
many more kits out there check ebay or google guitar amp kits
Join Ampgarage forum or Hoffman amps forum some really top amp builders on those forums that can help you out.

what Mark said - start with a kit. Just about anyone can build a tweed Champ or Princeton, and they are great amplifiers!
The first amp I ever built was a tweed princeton - and I still have it - and it still sounds great! |

I placed an order with CE Distributions AKA www.Tubesandmore.com for non dealer accounts because I plan to build another 5B6 cage amp.
I keep selling these 5b6 Tweed's as fast as I can build them and I'm not very fast after my heart surgery in January 2012 but I'm feeling up to it right now.
I can document the build process if your interested, probably in new thread though.
I use the Hammond black steel 12x8x2 chassis, bottom plate and steel top cage. Makes for a very cheap enclosure. I use the TIno Zottola layout plans (Same as LW's layout) but space the tubes further apart so I can use 6550, KT88 or KT120 tubes in addition to the standard 6L6GC's.

Hi Mark,
I'd be interested in following the build, for sure.
Thanks,

Thanks for all the links, Bob.
And I would love to have your build documented, Mark.
What is the layout for the 22/44 watt version? thanks
