Mahina lang naman ang power nito sir, 19-0-19vac lang ang supply. Pero sapat na talaga para music at movies, at kahit pa mag-karaoke.

Maganda tumunog ang class A, napakainit nga lang talaga. Meron akong class A bias na P3A dati na ginawan ko ng plywood na case. Nakalimutan ko minsan na naipatong ko yung isa kong plaka sa ibabaw ng amp, tumagos yung init sa plywood at nayupi yung plaka sa init. Hindi kasi ako naglalagay ng fan at medyo sagabal sa pakikinig ng music.
Pero basta malaki lang ang heatsink, kahit umabot sa init na di mo kaya hawakan ang heatsink tuloy pa rin ang amp at di nasisira.
Pero ang P3A na class AB ay parang class A din sa init.

Tube amp. Nakagamit lang ako ng tube sa guitar amp, 12ax7. Pero ang main amp ay P3A pa rin at ang tranny ay njl1302/njl3281 thermaltrak (yung lima ang paa).
