I have a 1992 Soho Quatro 4 tube, 2 channel preamp.It is a "better" version of a Kitty Hawk Quatro.The input jack on the front pannel has borken its threads. It is a Non PCB mount.and it is like a Marshall 9001 jack Not grounded to the front .If anyone EVER knows where I can find one PLEASE let me know >bacusbob@yahoo.com Also can I use a 6 pin Cliff jack Thanks

9 pin Jack

Yes it looks alittle like both and you are right the ground is on the top The only schematic I have seen that looks like it is the old Marshall 9001 preamp.Its a pretty good preamp for Clean and Crunch The other Hot channel I dont use to much.I do not know how to put a picture on this site.My girlfriend might be able to do it or send one over the phone....

I do not know what you mean about cutting two pins and a ground ? all I want to do is replace it.But I cant find one anywhere.It is just a Guitar preamp and the threads holding the nut to the front pannel broke.

Are they solder tabs (for soldering wires to directly), or does this jack mount onto a circuit board? I can't conceive of any reason you need a 8-pin + ground for a guitar jack. We'll assume the jack is shielded from the chassis for a reason.

Go to: [="http://www.neutrik.com/us/en/audio/203_411/Jacks_group.aspx"]Neutrik's / Rean website[/]="http://www.neutrik…"]Neutrik's / Rean website[/] and find which jack you think is correct.

Plan B: desolder the jack from Hot channel and move it over.

Your topic says 9-pin jack. You asked if you could get by with a six pin jack. I guess I'm wondering what is connected to all the pins. A six pin non-combo jack is often a switching jack. A nine pin jack is often a combo switching jack. I think I would completely remove the old jack and go to the link DVDHawk gave you. Really paw through the Neutrik site as they do really good pictures. A metal jack would probably alleviate the concern over breaking plastic threads.
