        Mission  772 mk2  stereo  power  amplifier  - grey :
   From designer Stan Curtis : The 772 power amplifier was a development of the Lecson AP4 Class A power amplifier but with a Class AB output stage based around three cascode pairs of MJ4502/MJ802 power transistors
   This was a dual monobloc with each channel having a huge power supply comprising a Holden & Fisher toriodal transformer and a pair of large Sprague computer grade capacitors
   As I recall this amplifier was good for about 160 watts per channel into 8 ohms and something like 250 watts per channel into 4 ohms

   This product was launched at the Harrogate Audio Fair where the prototype featured a novel feedback system which largely mittigated the effects of the loudspeaker cables
   A third cable was wired to the loudspeaker terminals and fed back a signal to the amplifier.  It was easy to hear it working but the idea was dropped for production as being "too complex" for the average buyer of the time

   Mission made approx 250 of these amplifiers in 1981/82 [this example is the mark 2 version, which must be even more rare]
   The Lecson AP4 was a monoblock that was produced in very small numbers in 1978 to 1979, and was considered better than the Krell KSA-50 when it was being shown in the US
   The only major difference between the AP4 and the 772 was how the design was biased (Class AB vs Class A for the Lecson) and that the 772 was a stereo amplifier
