Hello!
I have a superHermes and I think it has some pins broken. Anyone can send a
high quality photo for comparison? How many pins should be entering the 8049
socket?
Just look and see which have pins (or remains) soldered on - there is
one that has no pin/solder and should not be connected.
It is possible, of course, the pcb pad has been broken off. Look for
signs of the missing pad on the pcb.
The way to repair is to de-solder the broken pins. Then cut off
complete turned pins from a socket.
These should be placed in the appropriate holes of another socket, and
the new pins can be soldered. Use a low wattage iron, preferably with a
1mm bit or similar.
If you have pins/pads broken off from the pcb, of course connection will
be more difficult. Do all the pins with good pads first (as above).
Then solder thin mica-insulated patch wire to the end of the pcb
track(s). Put the relevant pins in the template and fit to sH. Then
solder the patch wire(s) to the relevant pin(s ) and fix with
carpenter's hot glue. Do not use anything more solid, as that will be
non-removable.
When you have done that, use the socket you just used as a template as a
piggyback when you fit sH. That way you will only break pins on the socket!
