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!

There is one pad with no pin, looks correct. There is a pin broken in half, I
have spare pins, so I will try to replace it. There is a pad broken off from
the PCB, the one on the corner, but it is not broken at all, only twisted,
slightly off.
There are 30 pins, aren't?
I don't know - no sH in front of me or a manual!
There is a circuit diagram in the manual.
Reinforce the loose pin (where the pad is broken) with carpenter's hot glue or
similar.

I've done everything you said and works fine.
Thank you very much.
Excellent. I am glad to hear that.
Tony
