i dont get any noise or hums at any volumn... just that when i mount the sockets on the casing the signal passes right through

does that happen? the case that i used is made of zinc

just mounted the amp onto a new plastic case... works well now

overall lesson learnt:
1) use bigger pots with stronger lugs
2) plastic casing
3) smaller gauge wires

had a real nice time assembling the amp...
gonna build another 4 more with the remaining chips

if you have that much more chips, i suggest you take a look at some better designs such as PIMETA/MINT/PPA or even the M3. i've ditched my PPA project after reading that M3 sounds much better. and i already ordered most of the parts for that project. sweat.gif
