seems like nobody else wants to play so i started another project, hope the pics are not too large.
take a blown up zetagi b550 4x mrf455 amplifier with same pcb as this and turn it into a wolf in sheeps clothing
,
remove most of the unwanted components and solder in some westgate ferrite with modded endplates.
add 4amp peak regulator circuit to feed the bias pass transistor,
remove mickeymouse fuse holders and preamp board,
add input coax, wrap transformers and burn fingers trying to tac windings in place, could do with 3 hands to solder them properly,
put it back in spare room untill i have sorted the AB/C bias boards for a friend.
