PV 2000

Hello folks

I've recently bought a rather old but seemingly working peavey pv 2000 and i've heard varying reviews about it.
My main gripe is that i've heard from various sources that running the amp into 2 ohms presents a few problems; over heating, cutting out certain freq., etc. I initially bought the amp for running kick bins at 2ohm with the high pass (150hz) and it would be a shame if theres an underlying problem and i'd have to take it back.

Has anyone here actually had any experiences with this amp and if so how has it fair'd, especially in a 2 ohm load as thats what im intending to run it in.

Also on a side note, is it possible to service these types of amps? (sorry im quite a novice at all this)

Many thanks
Mikkel

I assume this question is rhetorical.

"especially in a 2 ohm load as thats what im intending to run it in."

Amplifiers that are advertised as able to run 2Ω generally do quite well on 4Ω.

An exception to this might be the HD series from QSC. The 1850 is built with the 2450 chassis and a lower voltage transformer for the lower impedance.

A Crest CA6 can have the extra outputs added to make it the same as the CA9 chassis and able to handle a 2Ω load better.

A Crown 1200 can have the extra outputs added like the 2400.

Adding extra outputs on these amplifiers will improve the reliability into a lower impedance, not more power.

Obviously, the best solution is to buy another amplifier and run both at 4Ω. Large American sound companies use amplifiers rated at 2Ω loaded to 2Ω on mids and HF, but only load them to 4Ω on the low end. They also get new amplifiers every year or two, and sell off the used ones at their cost for the new ones (generally at or below the normal dealer cost) so their cost of ownership is zero and the amplifiers are always under warranty.
