I probably need to start a different build diary for this, but I went shopping at The Green Shed (not the Big Green Shed) but a place in Canberra next to the landfill site that sells reclaimed stuff for next to nothing. I was looking for parts for the cigar-box mini amp that I am building for the foot stomp (or other things).
For the princely sum of $5 I got this old Sanyo speaker:
It's as ugly as anything I can imagine, but paint can fix that, and it's the right size and the 6" 5W speaker is usable. It likely won't give anything like a solid thump, but this mini amp might end up being used for a completely different purpose anyway.
I also picked up the chassis of a Kustom Sienna 30W acoustic amp, again for $5:
It looks like someone let the magic smoke out of a cap in the power supply section:
While I can replace the cap and fuse, I would be worried about why it blew in the first place and whether there are other faults. I don't have a chassis, and if I went to the trouble to build one, I would want to put a homebrew tube amp in, not this. So I might strip it for parts. I can salvage all the pots, the knobs, jacks etc. Most passive components are not worth enough to desolder, but there is a nice JRC13700 opamp sitting on an adapter board that is just ready to use in a pedal. There is also a spring reverb unit that looks OK. Too large for a pedal but I might be able to use it somewhere else, like in the mini amp.
