[Elecraft] KPA1500 replacement devices

[M Cresap]

Anyone have an educated guess whether the ART1K6xx or ART2K0xx devices would be a drop in replacement for the currently used device in the KPA1500? Most of the interesting specs are within 10% of the current device, the open loop gain may be a dB or two higher (if the data sheets are really comparing apples to apples). 

The main attraction of the ART1K6 and ART2K0 devices is the higher peak voltage handling capability - 177 or 200 volts vice 135 volts for the current device. Maybe a higher peak voltage capability will keep the amplifier out of the repair shop due to external events like arcing baluns or antennas flexing in the wind.

The package styles are identical, the ART devices are in stock from a few of your favorite distributors, similar price to the current device, maybe the quiescent bias voltage would have to be tweaked a bit...
