Ahh never mind, it's all good. The KL-203 and most other RM amplifiers are very much Low drive units, we all know that. It just seems pointless for them to claim a max peak wattage input of 3 watts. On SSB when I ran one with a radio that had variable power I let it coast at 10-12 watts peak and it stayed pretty cool and sounded great. That's all I know.
