Hi. Just curious to know if it would be safe to turn over a modded Crack with extra large caps to look at the circuit after using the amp. Do the large caps need to be discharged before touching them? I installed 3 90UF 250V Dayton Caps and 3 Russian Teflon 4.7uF 250V caps and 2 Russian Teflon .056uF 500V caps. Thanks.
