I wanted to get one of those to try but they went nuts, nice normal ones are hitting 200 and it is a 2x60w amp. Maybe old school but that is still not a big amp. I bought a rubicon 302 for 70 instead. Last one I saw on there was listed as 800w, then 2x120w lol. Price near doubled late last year. If that is real you could nail someone for a lot of cash working, if prices stay up. I would likely grab it but that is stiff for a broken old amp just IMO. The 800w one was dirty/etc and went for well under 200. I fixed a 240, only IC was the PS driver. Not hard to work on. I have a newer ca70 2x35 that has half the outputs but same type as the 240. I've never seen a limited but then I never looked at them much until lately.

They've always been expensive. If you watch constantly, you can luck up on one for $90-125, typical selling range is $175-200. Keep in mind they were $550 new in the 80's. More expensive in $/watt than almost everything else.

Have you given the 240 a try?

I have one to test just figured it would not be large enough for mids/midbass, since I will run 4 ohms, unless I get another and bridge a pair. I have not used one in a car before. Also trying to get a nak pa304 to try. I don't care so much about names but they are good amps. In reality if I found a clean comparable cheaper amp I would use it and not care less, but nobody seems to know that kind of thing...everyone says they are the same but they usually sound different in my car. My issue is how it goes into distortion and how well it's sound works without EQ, as well as being clean. So far one of my favorites is an old alpine, have a feeling I may not care for the SS as they tend to be colder. Grabbing as many old amps as I can to try and then find out for myself. I've run LP for example, and I never thought they were that great in fidelity while people say they are the cat's rear. Great/powerful on subs and mids, but I felt they lacked detail higher up IMO. Used to run SS d series on highs/tweeter with LPs and that worked nicest. I saw some 260 go for ~125 but I got beat out.

It might take me weeks to get the time to hook all these amps up🙄 And I'll get sick of hearing the same songs every time.

id try sticking that hk in the car to see how it sounds, i have a couple old 60x2 watt audison amps, that believe it or not sounds better than a 2150sx on mid/hi's...

this audison uses some kind of weid emitter follower current gain topology with somekind of weird feedback loop that doesnt use opamps.

all i know is that it sounds good. 😀

Unfortunately I wired this 5ch amp tight, duh. Now I have to redo all the wiring to put anything else in there, don't think I left any extra. So when I do I'll lay amps on the floor and try them all or until I get tired of it. Did you buy the HK yet, you can send it to me if you are feeling nice and I will try to get it going...see if it sounds better than a pyramid.😀 This ca240 is that way, no op amps all transistors biased. It does have one channel slightly off but offset was still pretty low. Should replace some stuff not had time. I wonder how efficient these are.

Hi Joerg,

Id love the circuit diagrams and connection layout for this amp if you have them.

I went to check it out this past weekend, but something is wrong with it...after about 30 seconds of idling it starts to pull current exceeding 35 amps, the needle on the ameter rises slowly.

i have an audison amp that has the same problem.

thanks 🙂

In the CA240 I worked on everything is biased on, something knocks the current off and everything downstream is off. There was a small lack of voltage at one point and the amp would not make sound, think it was off by 1v or something at ~20v.
