.....I never expected Bruce to chime in on a Synchronar post. I bet he's a closet Synchronar fan with a whole pile of them in his collection
.
Well, I've never seen these variations on MkI PCBs before. Very interesting. I agree, those transistors do look like Pulsar equivalents.
Sometimes those pull down resistors are on the other side of the board....I've seen surface mount and axial varieties.
Since we're showing interesting MkI synch boards, I've got a MkI with a strange Monsanto display. It looks the same as normal, but there is a big gap between each segment on each digit. Much bigger than normal. I'll try to get a shot and post it. I'll have to use my mobile though, the camera's failed.
Rgds,
Andrew.
