Soon the Hydrogen and Nuclear amps are getting a heat sink change. Along with the heat sink change comes a new model in the Nuclear. The new heat sinks are similar to the Plutonium. They will have all the connections and controls on one side.
Models include:
Hydrogen:
GZHA 2400XII - 2 x 270 @ 4 ohms
GZHA 4150XII - 4 x 140 @ 4 ohms
GZHA 1800DXII - 700@4ohm 1200@2ohm 1850@1ohm
Nuclear:
GZNA 2850XII - 2 x 450 @ 4 ohm
GZNA 4350XII - 4 x 200 @ 4 ohm
GZNA 2500DXII - 850@4ohm 1500@2ohm 2300@1ohm
GZNA 6800XII - (staggered 6-ch) 4x80 & 2x150 @ 4ohm
