Which vintage amp to build?

Hello all.
I own a tweed champ, vibro champ, deluxe reverb and built a tweed deluxe.
Now I’m trying to decide on another amp to build and wanted it to be something different than I have, or something more unusual. And /or possibly filling the gap in between something I already have.
I was thinking either a tweed Harvard, vibrolux, or Princeton
Or brown Princeton or deluxe.
Anyone have any experience with these amps and have a love for one over another?
Thanks

I've built a 5F6A, 5E8A, 5F1, and Trainwreck Express. These were all Weber kits with my own tweaks and modifications. There are no instructions, just a schematic and wiring diagram. I also have a BSEE earned when vacuum tubes were still part of the curriculum. Yeah. I'm that old. 😂

Hi, I built a 50’s Princeton from a kit, it’s great but it’s basically a champ with a tone control. Are you building from a kit or are you experienced enough to build something yourself from a schematic?
My kit came from Modulus amplification here in the UK. https://modulusamplification.com/
They have a good and very varied selection. He was also able to put me onto a great cabinet maker.
Good luck whatever you do.

If you want to stay with Fender (I understand, I've built many Fender circuits and they are the best IMHO). A tweed Vibrolux or Harvard is similar to a 5E3, but still different enough. They are a little tighter. You could try something with a different phase inverter, like a paraphase pro or deluxe?

Brown Princeton (6G2) and the Harvard are both really cool and not real difficult amps to build. I've done both before and enjoyed them, though I did eventually sell both off, figuring I can always build more if I need that sound again. But for my needs, neither really produced enough clean headroom.

Are you UK or US? I’m sure they’ll ship, check them out, very good selection and if you phone them ,they’ll give you genuine advice and help. (I struggled a bit with the wiring diagrams and they were super helpful).

I have built almost four Marshall Clones almost because the Stewmac Brit-plex 45 was so fouled up by changes made over the years they just apologized and gave me my money back and are in the process of redesigning the amp kit. Since it was my first I needed some guidance, and stewmack had great instructions but did not keep up to date with the kit modifications and substitute parts. So Tube Depot did offer the JTM45+ head and combo which I opted for the head great kit and turned out good and gave me the basic order of assembly which I took to Mojotone for my next two builds. They did not offer anything but a layout but since I knew the basic order they were great experience and did a '72 super lead and just finished a JCM800 and it sounds fantastic with both my fender and Les Paul but I do favor the LP.IMG_3330.jpegIMG_3333.jpeg

A JTM-45 is a beautiful thing. Great cleans with plenty of headroom and some of the best-sounding overdrive you'll find anywhere if you build with the Drake-style output transformer. Just a stellar amp!JTM-45.jpg
