Octobass in action video, and inside the dissapointing SC200 PA

Will posted a vid up of the piece in action before we packed it up to go to Latitude festival, where it won the Contemporary art prize: http://www.flickr.com/photos/leadtowill/7610407178/in/photostream
Hopefully will get to make some more stuff like that.

Now this is something that got dumped at the bottom of the to do pile, but various things on top of it had transformer issues I can’t do much with. So dragged it out to strip. This was a Sound city 200 PA I spotted in a pile of junk for sale, I asked the guy if it had transformers in it, it did indeed. All excited, sorted a ride to go and get it. It had tiny transformers in it, and a big heatsink, someone had converted it to solid state, something I totally didn’t see coming.

Stripping it for minor spares like cap clamps and small bits of turret board is about all I can do, chassis too. Its been damp so the jacks and pots are crusty.

 

Sound City 200 up and running

Bah, wordpress decided to take me to some alternate simplified editor and made this post go weird, so bunches of edits happening.

Aside from a confused standby switch, due to strange things being done by the guy who left the notes, it is up and running, need to bias is properly, but it is sounding good and clean.

Boring stuff to do now like figuring how the switch turns the light on when its in standby, even though the light is wired across the switch, so it should be lit by the HT. Need a more awake brain for that. Might replace some wiring too. Sorted the outputs to be a normal 4 parallel jacks rather than the weird must have two plugs in it to work arrangement. The output selector wiring is a crazy mess and I have no idea why, unless they were scared to trim down wires coming from the OT, which I would agree with, like I never cut pickup wires down, in anticipation of swapping them out often.

Interested in buying bust amps if you have them.
