[Amps] KPA1500 Efficiency vs. RF-Kit B26

[Bill Steffey NY9H]

been following this thread for a while...  still waiting to see a 
comparison of KPA VS  RF-KIT .

I do know MY RFkit is sitting directly in front of me in my 
console...and makes some noise at FT8 800-1000 watts,, some , not even a 
lot. On SSB I don't even hear the fans. The Huawai 3KW PS is 96% 
efficient to start... The pallet has a VERY different heat sink arrangement.
