Re: Cleaning mini-jack sockets

2008-05-20 by aybee2004

Thanks Silas and Dieter for the information.

One of the racks in my system is from 1999 apparently, so it looks
like I have some hours of fun ahead of me as curl all the jack
contacts on the modules...

Can anyone recommend a pin-for-pin replacement jack socket?
It may be quicker for me to replace the sockets - assuming there are
no double sided pcb's.

thanks again

Andy
