[QUOTE="Ivan Beaver, post: 42962, member: 30"] Re: Sorry, but I had to show this. Since I didn't have any money (I built everything back then-mixers-amps-processing etc), I took the cheap route. There was a surplus store in the Chicago area that I used to get all sorts of "stuff" that I built with. In order to get what I wanted, I also had to get "extra" stuff-extra output windings etc. This accounted for the extra size and weight of the transformers. The 2 transformers have the inputs in parallel and the outputs in series-creating a center tap-so to speak. The center was the ground and the "outside legs" went to a single 25A bridge rectifier-then to the caps-one for each the + and- supplies. So pretty normal stuff there. Yes the sign was Aluminum. I did get it the legal way. The highway dept would give old signs to the school I went to, so we could make things our of them. On the sides that were "touching" other layers and the outputs, I sanded them down good (to get through the thick crumpeled paint) and used LOTS of heat sink compound and bolts to hold it together tightly. While not as good as a real heatsink-they did what I needed them to and never had a problem overheating. You do what you have to when you have no money. This is NO LIE, I actually used to twist my broken guitar strings back together and solder them. You just have to make sure that the "blob" was between frets and you don't play those notes. After a couple would break-I would go to the local Western Auto store and buy Black Diamond strings. They were the only store in the county that had guitar strings. Times were different back then.
