This amp is using CEP75n06's as the power supply fets with 100 ohm gate resistors and C945 and A733 as the drivers.


Is there a good sub for the 75n06's ?

The IRF3205s, 47 ohm resistors and BD139 and BD140 drivers should be OK.

Would the orginal drivers still work with the 3205's? or should i order the BD139's and 140's?

The original drivers are only rated for 100ma. They may hold up but I'd suggest something rated a bit higher. You need to have the BD139 and BD140 on hand anyway so order them.

Ill have to order some up..


I found 2 BD139's and put thoose in the amp..

Just for testing will the KTA1275's work to see if i have anymore problems?

Nevermind i found a couple BD140's
