What would be the closest kit I could order and build that is similar to a Pro Jr?
I could give it a try, I was after the Sweet Spot a couple of years ago but my needs have changed. Oddly, Nik from Ceriatone suggested his Princeton clone to me.You could also check Allen Amp's site. I built one of their kits back in the early 2000's and it was excellent.
I've read that the Pro Jr. Is closest to the Tremolux circuit than anything else. Also similar to the 18W Marshall.The Pro Jr had a little Tweed sound to it, a 5E3 perhaps? Different in the physical sense but crossed over a bit sound wise, unfortunately I've built that already.
That's a good idea. Lots of 18W Marshal kits out there @vadsy , same power tubes, similar sound.I've read that the Pro Jr. Is closest to the Tremolux circuit than anything else. Also similar to the 18W Marshall.
