I have just finished a Princeton 5F2 pushing a 10" Jupiter "10SC" and the sound @ tone is outstanding can't wait till its broke in.
Took around 3 months of hard labor, the wiring was a little tough haven't done any of this for 35 yrs put together a Heath Kit 100 watt solid states that was really a chore, now at 72 and doing the wiring @ woodwork wasn't to easy with old arthur and brother Ritus but I'm very satisfied.
note: if you need any advise talk to Mike @ fender vintage amp repair he is very wise and particular about things...
