Default should i ???: HK260

should i add another amp to my pile of amps that are not in use?

I can get this amp in cherry condition for around $125

somethings probably wrong with it though....any parts i should look out for that may be hard to replace?

does this amp use a pwm chip or is the ps self oscillating?

i think this was one of those idle hogs.

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.
