Is it normal for sams to skip a model? my orginal post back in december on silvertone console.I'll can find a model 141 and model 143A chassis 100.111,but riders calls mine a 142 chassis 100.115.the cabinet is just like the 143a but a different picture tube(143a is a 16rp4,142 is a 12lp4a) and the horiz. ouput tube is different at a quick glance at the circuit.
