I took an alternate route to the jack problem. I have a crate modeling amp that quit working. Not sure of the problem right now, don't really care right now, cause I haven't liked that amp for a while. It did however have a 12" 4ohm speaker in the cab. I also recently had a very old Boss SD-1 distortion pedal quit working. So, I took the input jack out of the SD-1 and "kind of" attached it to the back of the "Crate open back" cab I now have. Now I have a working 4 ohm Crate extension cab for my Epi Valve jr. head in addition to the Line6 Flex III 8ohm extension cab. In addition, I can try to use the metal housing for the kaput SD-1 for an effects pedal project in the near future. "Work with what ya got!"
It is a small world for metal fanatics. I welcome you fellow musicians, especially the metalheads!
97Reb has it. All you really need is a little 1/4" jack from Radio shack and maybe a little wire. Just snip off the speaker leads in your Princeton (doesn't work anyway), solder the wires and connect the jack and you are good to go.
I am thinking about ordering one of those 12" cabs for my Valve Junior. I swapped the Eminence 8 ohm 12" in my HRD for a Celestion a few months back, I could put it in one of those cabs. Looking at the pics they looked pretty nice and I read a few reviews which were good also. That would be a perfect pick-up-and-go setup for this head, just right for the Open Mic.
The kits looked OK too.
