[quote name='BOD2' post='202656' date='May 20 2008, 10:05 AM']Is it one of these fully enclosed plastic jack sockets that are soldered directly onto a PCB ?
I had to replace a couple of these on my HA3500. They're not the best quality jacks unfortunately but, because of the PCB mounting, it can be tricky to get replacements (have to ask Hartke for them).
It might be possible to repace the jack with an "open type" Switchcraft jack and just solder wires from the jack socket and onto the PCB ? It's a bit fiddly but the end result would be a much sturdier jack socket. I did something similar to this on an small Fender Champ because the cheap plastic Fender jack sockets were brittle and would fall apart through use.[/quote]
Cheers BOD, yes it is one of the enclosed type....you've hit the nail right on the head, it has to be the jack, suppose it makes sense if you had to replace them on a HA3500.....tidy darts! I was beginning to think the amp was just unreliable
Ta very much!
