A little bit of an update –
I replaced the cap on the 5V supply, which was cracked.
I replaced the insulator card over the power supply, which had been mislaid.
The clipping wire was attached to earth – I placed it back to where it should be.
I started it up with the outputs disconnected to be greeted with a good working display, no dead segments etc.
Reconnected the outputs and tried again, to be greeted with sound. I just had little x25s attached, so the sound was nothing remarkable.
I won’t hook it up to the MS150.2s until after I replace the fuse board RIFA.
The unit has three service stickers on it and I notice the power amp trim pots have been upgraded. Some original caps remain.
On that basis I’m tempted to just push it into service, pending RIFA replacement.
