@jfrmusic 6 transistors / leg, 12 total pnp-npn power devices per channel. I calculated A class wattage using p4600 schematic.
Watts! How many do we need?
Got a new amp. Accuphase P-4600. It’s great. I love it.
150 watts into 8 ohms, 300 watts into 4 ohms and it has meters so I can see wattage. Have them set on freeze so I can see the highest wattage during the session.
My Harbeth speakers are not very efficient. Around 86db. Their impedance is an even 6 ohms dipping no lower than 5.8 ohms.
Playing HiRes dynamic classical recordings ( Tchaikovsky , Mahler) at room filling volumes I have yet to exceed 1watt..
Amps today offer a lot of watts some going to 600 even 1200 watts. Even if you have inefficient speakers with an impedance that dips down to 2 ohms do we need all this wattage or should we be focusing on current instead?
