MY NEXT PROJECT

They say that amp building can be habit forming, and it's true. Go here to see pics of my second build:

My Amp Builds

Specs from Firefly combo as outlined at AX84.com Great crunch at reasonable levels.

I like the pictures along the way. I'm thinking of building the amp in Dave Hunter's book, how much should I expect to spend? I see the Epiphone Valve Junior head (very similar in size and power) for about 100 bucks and obviously they don't use the same quality parts as most people would consider using. Thanks for any info.

Hi Pete-

I have seen those valve juniors and they look very cool. The most expensive parts on the two-stroke are the transformers. The Output transformer is about $35 from Antique Electronic Supply (www.tubesandmore.com) and the Power Transformer for about the same price. Then it's the chassis ($14-$20). The filter caps are the most expensive of the electronic components. My buddy had the eyelet board and lots of the resistors and small capacitors, but these are real cheap from Mouser. Shipping will get you on most of this stuff unless you have a good local electronics store.
The speaker cab can set you back a lot depending on what you want....

You could make a Two-Stroke like the one I built (head only, not combo) for parts you get yourself for under $200.
If you want to go really cheap, you could try to cannibalize an existing combo- I did that with this amp (not a two-stroke): http://new.photos.yahoo.com/mystro2b

I'll try and find my original parts list/email from the places I bought stuff from if you need more of a specific idea. EMAIL ME AT pendergaurd-blogger AT yahoo if you are interested. Right now I noticed at Antique Electronic Supply, everything is 10% off until the end of December 2006. These guys are great to order from.

Here is a link to another amp I built, The High Octane: http://homepage.mac.com/mystro2b/
myHO/PhotoAlbum10.html- I love the sound of this thing- It would cost about the same as the Two-stroke but is a bit trickier to build if you are a first time amp builder.
Good luck!
