I'm about to build a bi polar power supply to power some electronic effects for electric guitar that I've built that I'm sick of putting two 9v batteries in. The basic schematic and design is the one in the Craig Anderton books. So, here's my first dumb question:
- The power transformer should be mounted right on the chassis, right? That's what I've seen in every other piece of equipment I've poked my nose in, but I figured I'd get a second opinion here.
- The voltage regulators I got from mouser (according to their tech) require no heat sinks, as they're insulated with something. Is it a bad idea to use these in a project that might be turned on for several hours at a time? Should I get the "old" style regulators and use sinks instead of these insulated ones? My concern is that while the regulators may not be a danger to nearby capacitors, will they be prone to shut down more quickly than the ones that require sinks? I'm not going to put any caps too close to them anyway, but if anyone out there has built this before mabye you could share your troubleshooting experience with a less experienced builder. Thanks in advance, Jason Myers
