So I am still working on my 38-12 and I am attacking some nasty looking resistors. I noticed alot of posts regarding what wattage and a link to Philco Bench but when I click on it I get an error that page could not be found. Is there another resource? Also, if I can't get the exact ohm rating for a resistor, can I go a bit higher or lower? Example: if the schematic calls for a 200 ohm resistor, can I use a 220? Thanks for helping with these questions. Also, in line with the wattage question, I am shopping for a kit with single wattage assortment of resistors and are there any recommendations on this?
