Many moon ago I was given several reels of parts tape, the kind used by automated board stuffing machines.
A good reel of parts can provide hundreds (if not thousands) of 1k Ohm 1/4 watt metal film resistors and soak up many hours in sorting the goods but can be a good way to build your inventory of common value parts on the cheap. Some reels have a nice assortment of Zener and other small signal diodes and I was lucky enough to score one that included a bunch of 1N5711 and 1N270 diodes. Both part #'s original HP.http://www.alldatasheet.com/datasheet-pdf/pdf/64551/HP/1N5711.html
As mentioned earlier, the 1N5711's are Schottky pieces intended for VHF & UHF mixers that feature the low forward drop of Germanium with the low noise and higher reverse voltage rating of Silicon. I have been upgrading the detectors in some of my stereo receivers with them and at 455 kHz or 10.7 MHz they are grossly under stressed.
In my experience they do sound better for maybe an hour or so. Then I get used to the improvement and it doesn't matter so much, although I never get tired of the quieter noise floor. If I had to pay retail for the diodes I'd probably pass as they can run $3.00 - $4.00 each, but as a freebie?
