Help much appreciated! |> My sister's fairly ancient Sony receiver was exhibiting some problems. The repair place told her it wasn't worth fixing so I decided to do it myself. Nobody in Ottawa could find a schematic for it, and a call to Sony Canada led nowhere. I found Sony's U.S. 800 number for technical publications in rec.video and called it; $2.50 on my MasterCard and three days, and I had all of the user and technical guides for the receiver. I had to replace a capacitor in the power supply. |> -- |> Markus Wandel Ottawa Ont. Canada (613) 592-1225 |> markus@pinetree.org <-- NOT 'mwandel@bnr.ca', that does not work. -- D.W.J.
