here are a few kick ass sites to source parts on the cheap. the first is EVITA. they are a great source for any russian parts that you might want, and are even cheaper than what you can find them for on ebay. plus you don't have to buy a box of 100 of a single type, you can mix and match as you please. i have heard that they have reasonable shipping, and EVITA has all of the datasheets available for download on there sight, so you have some idea of what you are getting into.
as you can probably tell, i have a serious passion for these russkie germanium trannies, as many types are about as consistent as any silicon transistor out there, and unlike euro, american, or japanese trannies, many types have absolutely no leakage. the consistency of russian ge transistors is pretty much unparalleled around the world. i think this must be due to the fact that the soviets were producing germaniums well into the 80's where other sources had stopped long before. also they used them for many military uses as well, so their standards were set very high. you can tell the transistors and other parts meant for military use as they have a small diamond printed on the side.
along with transistors, there are many excellent russian teflon, paper in oil, and polystyrene capacitors offered at EVITA, so if you have an urge for cheap, quality soviet parts, now you don't have to be a slave to ebay.
if you have ever built an analog delay, you know how hard it is to source bucket brigade delay chips. you can end up paying a hefty price for what may end up being total counterfeit crap. you can go to a parts sourcer, but there may be a large minimum order that puts buying the parts well out of your price range. well, i recently was turned on to UTSOURCE, who source hard to find, out of production parts with very small minimum orders and good prices to boot. give em a shot if there are some rare chips you can't find.
lastly, is TEDDS.COM. they have lots of cool vintage capacitors and other parts with only a ten dollar minimum. also, they have pics of every cap in their inventory so you don't have to have every model number memorized. good stuff.
