I guess I get the allure of kits from ebay for the cheap prices, assuming the components are a) genuine, and b) decent quality.
However, buying a kit and then coming on here without apparently doing a modicum of research first is very bad form. The links to Kevin's board files and schematics/other files are here, but might require a bit of digging. Since that vendor supplies both kits and built units (for a whopping $10 more), one might assume that they build with the same parts as they supply in the kit, and it might not matter whether you use a 1K or 10K resistor in the 2 spots. If you're worried about it, then use some 1K for those two positions.
But otherwise, the appropriate head-case response is...
