Long time between drinks but my attention has been back on some High End games which I've made steady progress on. In this case, the Joker Poker has been resumed and it is time to turn my attention to the baseboard transformer panel. It is a standard affair with original parts and unbelievably, correct fuses installed !
That crusty old EMI filter will be gone soon !
A mixture of original 1N914 Switching diodes and what appears to be a 1N4148 (modern equivalent).
All of which will be replaced. First the baseboard is sanded, and the diodes are replaced with 1N4148 ;
Mains fuse holder is replaced with an original NOS fuse holder. The old one looked ok, but looking closely - there's corrosion.
Moving on to the connectors. Nice and furry !
Replaced all pins in all connectors ;
Transformers are cleaned and polished. I don't need to paint them as they are fine. But I do dismantle them and polishe the mounting brackets and screws.
Correct fuses and laminated original fuse card stapled ;
The Bridge rectifier plate is re plated as well as the utility outlet - which is disabled, but re installed for aesthetic purposes.
The completed base board - ready for testing and installation. New EMI filter installed and I will install a new power cord.
