The MASTR Exec (1) came in two flavors (at least here in Canada), the Exec with a tube final and the Royal Exec with a solid state final. The receivers in both cases was very similar. The receivers are very sensitive and also quite tough. I saw one where the input trace on the circuit board had evaporated due to an arc (from induced lightning) to the case 1/8 inch away. Jumpered the trace and the RX sensitivity came back to normal.
BTW the Exec receiver makes a very good 220 receiver. The majority of 220 repeaters here in the Montreal area use them. Burt VE2BMQ John J.
