sources for caps / resistors / connectors / insulation pads and heatsinks?
I have found pretty much all the transistors / diodes I need but am at a loss as to where to get resistors / caps / connectors or insulation pads / heatsinks?
I tried digikey but they don't have a good selection of pads / heatsinks and the rest is quite expesnive buying individually from them.
Where do you get yours?
I thought the Bergquist page in the digikey catalog was more than sufficient.
If for heatsinks you mean for output transistors, the only really cheap means is surplus items on e-bay or a local surplus store if you have one or kluge your own from scrap metal. For something like the ESP P3A, I've "made do" by taking a piece of aluminum bar stock and bolting on a mess of old CPU heatsinks. Ugly in the extreme but effective.
If you want pretty heat sinks or somethinh really substantial, the best source for the hobbiest may be M&M Metals (www.mmmetals.com, I think). Minimum order is $100, so you may want to think ahead to future projects and buy in advance.
Try this for heatsinks...those are probably the hardest part of doing an amp...sourcing all the parts. You can get a lot of stuff from digikey, www.partsexpress.com, www.newarkinone.com and a local scrap metal place. Ask around locally, there are always scrap metal places around. Later!
