Hello All,I think this is probably the best place to ask this question....How critical are bypass cap values? I have an integrated tube amp with two, cheap .33 uF 630 volt bypass caps. I have in stock some very nice AN .22 uF 630 volt caps I would like to try. Good idea or bad idea? Thanks in advance for any insight.Mike
Hi Buddy,Thanks for your reply. You’re right, they are coupling caps not bypass caps, I misspoke. I have used these AN copper in oil caps as coupling caps in the past with very good results. I’ll pony up and stick with the original .33 value. Mike
Most important rules in replacing capacitors:1. Acquire and learn how to use a capacitor meter. The value of a capacitor is not the number printed on its case, it is the actual measured value. This value can be substantially different from the printed on the case value depending upon the type of capacitor.2. Replace capacitors with measured matched pairs, left to right channel.3. Make certain that you are using non-polarized capacitors in any application that specifies this. Polarized capacitors will break down if reverse voltage is applied to them. In general, most electrolytic capacitors are polarized, most film capacitors are not, but check to make sure unless you want loud BANGS and smoke at turn on.Frank
