NEED HELP ON AMPEG V-4B

[SNOTROCKET56]

I just recently acquired a big ol ampeg 2x15 from the 70s, its a v-4b - my question is how do i know what kind of amp to use - i dont think my gk 400rbIV will handle it

I think it would handle it easily. Those old cabs from the 70's sound great, but they don't handle a lot of power. I'd guess the V4B cab to be about 150-175w power handling or thereabouts, unless the speakers have been replaced with either the higher power handling JBL or Altec speakers of the day or new speakers that handle a lot more power.

The GK 400rbIV can handle it. The cab is rated 400 watts @ 4ohms if it's the Classic ReIssue from the 90's. If it's an actual 70's cab, it's rated 240 watts @ 4 ohms.
heres a link to the brochures:

I would do what JimmyM said. But save the original drivers just in case you decide to sell the cab (becuz they're rare) to a collector who wants the cab in original form. IMO

Thx for the actual specs, Darius. Didn't actually recommend him to replace the speakers, though. Actually, knowing it'll handle 240w legit, I think the 400RB would be fine for it, although it would look a little weird without a V4b on top of it

* Yeah I know, not sure if the grill cloth is removable, since it's a folded horn design, grilless might look OK with a GK head. eh

Heres a link to alot of the manuals and brochures for the Ampeg v4

That's good power for that cab, will be just fine.
