KL503

Without seeing the layout it does resemble a pair of KL203's with a driver.
I kl203 will do 160-200W PEP on SSB so I guess the KL503 should max out around 320-400 depending on frequency. Like the 203 it will probably only work well from 18-30mhz as on mine the input SWR rises to 2.5-3 to One on 14mhz.
Still put out some signal but it may affect the drive radio.
from 18mhz on up no problems.
cheers,
Dave
