Later B&K 1077B
Hi All;
I have a B&K 1077B, which is different than the other two that I have.. One is that its uses a different CRT, the base where the socket plugs in is smaller in Diameter than the others and it has foil wrapped around its neck.. The others are the 5BP4 variety, can't say for sure, as the number is no longer on the tube.. Also on the Board below the neck of the tube, on the right side, while looking at the front of the B&K unit.. That Board has two IC's, they both are cmos 4013's.. Anybody else have these later units and can anyone tell me what the IC's do ?? My schematic doesn't have any Ic's..
THANK YOU Marty
