I remember seeing the wiring for an old electric chair once. The coper strips remind me of the wiring.

Seems like you couls nickname the amp "ole sparky"?

Looking at those heatsink fins, how hot does this amp get?

Default temp after 1hr run

hi,

i am not professional in electronics. as it is, you seen some scratches but under the transistors are very nice shape no scratches at all...also i have touched each of the mosfets to check the temp, it is really nice and worm but not abnormal hot.

honestly tells you. yes this aleph-3 amp sound sweeter then aleph-x and my othes amps too.

i also made aleph-x but i will require more testing on that. oneday i will make aleph-x 100w too. wait for until i finish my aleph-3.

i have tested first aleph-3 30w then slowly made it into 60w and observed the sound quality and temp then now 105w. its sound really nice and worm sweet. now this amp can handle my big speaker. actually aleph-3 more easy to make 105w, i set the bias into 15w par pair so now i am using 7 pair X 15w = 105wrms into 8homs.

at first i was scare of temp due to using small heat sink and the temp went over 80c. wow....i was so scare.....later i came out to calulate how big my heat sink should be. then i arranged this plate to make heat sink.

now my heat sink can handle such huge 105w amp. today i started to make another channel for this amp.

soon i will be finishing my this 105w amp.

i really love it....
