Racal 1992

<< < (5/5)

SeanB:
Those sockets I got 2 turned pin sockets, soldered the one to the board, and soldered the other to the IC, solving both the intermittent connection problem, and the fragile leg issue as well. Was not in  a Racal, though there was one in the rack, but in the custom boards there that were doing digital logic and such, where the one leg on a fusible link prom was intermittent, and there was no way i was going to easily change that 16 pin wire wrrap socket, as all the wires had been wrapped and soldered during manufacture, so just a new socket with turned pins, so you could reach to the contact point with solder, was the solution, and the other socket with the IC soldered to it fixed the broken leg tip. One hour of work, after identifying the issue, as opposed to the guess of at least a week to get to that particular socket, buried in the middle of a stack of boards.

Since IC39 is only available as a salvaged part, you should add a heatsink to lower the temperature and hopefully extend the chip's life.  Heatsinks are available in stick-on or clip-on versions but they're getting hard to find.  One such clip-on model is:

My junk box coughed up a similar heat sink that I put on my 1992.
