Actually, only one half of plate dissipation. The ICAS dissipation for a single 813 is 125 watts, CCS is 100 watts.. This is the maximum carrier for reasonable tube life. Efficiency is low without modulation., increases during modulation. Limiting factor is one half total dissipation.Sorry but the facts are so. Mike
