In Reply to: Choosing Resistors... posted by bamadawg_63 on December 22, 2005 at 06:07:37:
is the best overall of the ones you listed. If there are any series resistors the signal has to propogate though as in lo, high or bandpass filters I'd use tantalum. If I couldn't afford those I'd use Dale/Vishay RN65D Or RN60D metal film. For the first voltage gain stage plate and cathode resistors I'd use Holco non inductive wire wound, 3 watt. For signal polyprolylene caps I'd look at the SBC 716P series. I'd also seriously find Russian Teflons from Latvia (the problem is finding the same values as are in your amp). You can find them on ebay. I wouldn't buy designer caps. I'd use a oil cap as the first power supply cap instead of an aluminum electrolytic (GE, CDE/Mallory make them)You can find them at motor shops and on ebay. If the rectifier is tube than I would not use much more than the recommended capacitance as stipulated in the tube manufacturer's recommendation on the data sheet (Frank's electron tube pages). Most are under 10 ufd as the first cap after the rectifier. Too much capacitance here can cause premature rectifier failure. Good luck! Ray
