| Caps what are the best? When building tube preamps what are the best caps to use? I have used some of the best and wonder if I have wasted money on the components . I wonder ? |

| IMO caps are a waste of money from a certain price range up, like say 3-5 bucks or above for small value poly, metal films, etc. and this is for signal caps (bypass, tone controls). Electrolytics can always benefit from parallelling with smaller values, which lowers the ESR. Rather spend the money on good NOS tubes, sockets, and especially transformers.

| A totally subjective decision. Guitar amps are the extension of the instrument so you will find as many opinions on this subject as there are with guitars. Many are vintage oriented, they like older mylar caps, maybe paper ones. I like high voltage polypropylene film caps for coupling and low/mid EQ, I use silver mics'a for top boost and brite circuits. Older designed parts and mylar's sound too mushy for me. Jim Williams Audio Upgrades |

| There are also the os-con electrolytics caps , very fine for many uses. They are good for decoupling if large values are request, but in no polarized configuration. We should not forget the GOG caps , they are very good.

| a tip: when you spend time changing caps inside an amp it can really maka a big difference redoing all the grounds, starpoint stile. did this with a marshall superbass and the result was amazing. never before heard so much tone so loud and it was so quiet while not playing. i used polypropylene and silver-mica and ruby condensers in that one.

| Sure. If a ground wires are soldered in wrong places (like in few Ampeg SVT amps I had to after-market-correct) better caps would make hum and whistles even louder.

| Atoms are good caps, but you should probably bypass with a small value in parallel (to lower esr). If you feel like getting fancy you can use Elna Cerafine or better yet some custom Cornell Dubilier's (imo a waste of money).
