We had idea to construct 70 MHz to 14 MHz transverter on identical PCB as MURKA - 144 MHz transverter. We used pin compatible hybrid amplifier RA07H0608M. Substituting all frequency dependent elements and with a little bit of experimenting we built a nice 70 MHz transverter. All mechanical parts and housing stayed the same.
