FS: power supply assortments
¿ªÔÆÌåÓýHello-- Once again, I'm offering power-supply assortments FS. There are two flavors:1.) All Wall Warts-- a medium-size USPS flat-rate carton stuffed with as many AC and DC wall warts as will safely fit¡ªtypically at least 14 minimum. These may span the 3-volt to 48-volt range and will feature various output connectors. These are offered on an as-is basis, and it's up to you to verify that they work in your applications. The price is $23.00 which includes USPS flat-rate postage, a $17.10 ¡°value¡±. 2.) Some Warts and Open-frame Power Supplies These assortments are a mixture of wall warts and open-frame linear and switched-mode power supplies which fills a large USPS flat-rate carton (a $22.80 postage ¡°value). **NOTE: these supplies may have exposed AC power connections and are NOT recommended for unsupervised beginning electronics builders. The price is $28.00 ...and now for some FAQs... Q: Will my assortment include a Chow Foon Electric 3.14 V 22A Laser Pump? A: That's extremely unlikely.Q: Are these guaranteed? A: They're untested, and it's up to you to make sure they'resuitable for your project and are safely applied. Q: What good is a low-voltage Wall Wart (WW) in tube circuits? A: Want to experiment with a1940s one-tube regenerative receiver design?Use a 5-volt WW to light up a 5U8 triode-pentode tube and a 15-volt WW for its plate power supply. Q: Are you getting rich from this offer? A: In my dreams! The best I can do is clear some shelf space.Q: Do you accept PayPal? A: I thought you'd never ask-- yes, I do.
