Dear friends, Mike PinkFloyd after having completely modded my Musical Fidelity XCan v3 in vacation, thanks to Mike's projects and components, I'm now back in Milan and placing my super headphone ampli in its place... but moving the little Auricsound A7 hybrid-tube amplifier (that drives my studio station JohnBlue JB3 speakers) I heard something... argh... "moving inside". I opened the top and saw the protection of an electrolytic cap popped out (a Sanyo 470uF/25V/105° cap). Nonetheless the ampli was working, with no apparent problem. imgur.com/a/O9tMSIlI purchased this A7 ampli less than one year ago, and it's chi-fi, I know, but very good sounding (for the price range) and nicely built / designed, so it seems strange a jap cap did have this issue. imgur.com/a/v7enCVqTrying to put the protection back in place, I see the top is a bit curved, so it's evident the cap did "enlarge" (even if apparently it's ok). Now I've ordered on amazon a Panasonic cap with the same data (470uF/25V/105), and I'll receive it in about 10 days. imgur.com/rGpvkJ8Do you know if it's better not to use the A7 ampli in the meantime, or I could damage it? And did I do right in buying a same data cap or I'd better have chosen a cap with "higher data"? (higher uF, volts and/or temp?)
Many thanks
