Picked up the 1225 w/ original manual, AT cartridge but in cheap home made base and w/o dust cover, pair of Advent 2W that need to be refoamed and an old Wollensak R2R (didn't want it but he insisted I take it to get the deal LoL) for $40.00.
Was told everything worked but I think his defination of worked and mine are a bit different. LoL.
Anyway, got it home and checked on the base and it looked like it would work. I removed the top off the home made base and then removed the 1015F from it's base and checked the template from the 1225 against it and voila! perfect match.
I proceeded to drop the 1225 into it's new, nice United Audio base and it looks great. Then fired it up and one channel is much louder and there is a ground hum like noise.
I didn't have much time to investigate so I guess I have some work ahead of me but I was at least happy to learn that the bases are interchangeable.
