Part two of the Beckman 6145 counter teardown.
I still need to convert it for UK mains, the transformer has the usual split primary windings so this shouldn't be too difficult, I'm going to wait for the manual first as it has some extra windings.
I'm not sure I like how they crammed the line filter in there, the power cord really needs replacing to as it's not in the best condition from being wrapped around the unit when they shipped it.

The power supply/regulator section, I hope I don't need to change any of the can electrolytics as the wiring is quite a rats nest.

Lots of knackered looking wet tants

on the EL supply board, both this & the regulator boards have had some repairs.

The crystal oven section, this differs from what is shown on the inside cover, as the extra board for the 1MHz divider is not shown (only one that faces the other way too), this board has also been repaired at some point.
