I use BC547's by the thousands. KEC or Philips. My buying price is $US0.0167 each. BC639/40 are about 3 times that. 2. Ceramic resonators - someone else was asking - are generic, also easy to get here with 2 caps built in. Price $US0.064 is what I buy them for. regards, Peter Crowcroft DIY Electronics (HK) Ltd PO Box 88458, Sham Shui Po, Hong Kong Factory: voice 852-2304 2250 Fax: 852-2729 1400 M/F, 97 Fuk Wa Street, Sham Shui Po Home: voice 852-2720 0255 Mobile: 6273 2049 Web: http://kitsrus.com Email: peter@kitsrus.com ------------------------------------------------------------- -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
