Resistors
Finally got fed up with the shit most places sell, so started lurking on Fleabay for resistors and surprisingly enough there is a plethora of options available.
Today these showed up in my mailbox:
Straight outta Lithuania, old school USSR stuff. Claimed 10% tolerance, measured 10 and closer to 5% typical. These were less than $0.50 each, shipped from Eastern Europe.
I'll admit - looks matter to me, even though crossovers are buried in a cabinet. I have also been replacing my huge inventory of other values with various Dale/Ohmite/USSR stuff such as these 6.8 ohm jobbers for around $0.80/each:
That being said, I now have a box with a metric fuckton of sandcast resistors to give away at DDIY. Winner of a death match takes them home for the low, low price of free. Many have short leads etc (I am a fidgety prototyper).
For the record, I considered the heat sinked options - until I remembered something from my electronics 101 class 12 years ago: power handling absent being mounted to a heat sink is actually compromised on a heat sinked resistor compared to sandcast or silicone/enamel coated so I passed on stocking my resistor box with those.

I have a signature.
