[QUOTE="MusicMan_ZA, post: 945027, member: 14924"] Ok, now a general question about building e.g. a Muffsy PP3: I thought I would put together a component part number/price list from RS to build this PPA. The second item I needed is a 130-Ohm 0.25W 1% metal film capacitor. Not available, unless I buy a pack of 5000. Not happening. If I change the specs, I can buy a pack of 20, at about R5 each, of 130-Ohm 0.5W 5% mf capacitors. ("wrong" W and "wrong" %). My question: What parameters are "changeable" without messing things up, in this case: the Ohm? (I think not) the Watt? If so, by how much? the %variance? If so, by how much? Or what combination of the above? Or none? Please help! J [/QUOTE]
