Durahms's electronics in LR. Give Arville a call. Been around a long time.
Thanks for the info, I'll give them a call.

I would like to get my HK 730 serviced.....any recommendations for a good technician in the central AR area? I need to get a bulb replaced, caps updated, etc, maybe even a better power supply.
Thanks for your help!

I picked up a 730 about 2 yrs ago to run my LS's. Before I got it, I was using an HK AV347 reciever, which sounded pretty good. I was/and still am very amazed how much better the 730 sounds.....it is very noticable. I also have a Sansui AU-717, which is a very good integrated amp, but the 730 wins out. I have never heard or owned a tube amp, but it is hard to imagine they could sound any better than the HK 730 (I don't have any experience with the 430 or other models). At some point I may try a tube amp, but right now I'm very satisfied with the 730. It makes the LS's really sing......warm and detailed, with a lot of punch. Most of my friends don't believe it is just a 45W amp.....at about 1/3 on volume dial, it rocks the foundation.
For those of you who have owned one of these twin-powered amps and also a tube amp......are tubes that much better?

I have posted a thread in the Garage Sale section looking for a single (or pair) K-48-KP woofer. Since this is a Pro Audio component, I thought I might also look here. Let me know if you have any you would like to part with.
Thanks,

Not sure what they are worth.. Make me an offer..
PM sent.

Ok, I finally got around to testing the resistance of the drivers with my multimeter.....the mid-horn reads 12.6, while the tweeter reads 1 (which indicates it is bad). I guess I need a replacement diaphram for the tweeter, as indicated by previous feedback. What about the mid-driver......does the reading appear to be OK?
Thanks,

Thanks for all the feedback.
The guy I bought them from said he tested them before shipping, and claims they both worked great before boxing them up. When I received them, the boxes seemed to be in decent shape.....no signs of falling off a truck. But, when I hooked them up, I experienced the problem with the one speaker. I will test the driver on the tweeter and mid-horn this evening, to make sure they are good. I'll also check the fuses again, but both of them on the back of the speaker appeared to be good.....no dark or broken areas. I'll keep you posted on my findings......Thanks again for your help!

I just got a pair of KP301's, but one of them is not working properly. It has no sound coming from mid-horn or twitter....but the woofer appears to work....it rumbles. I took woofer out and checked the wires, I fixed a loose connection and one connection on terminal block that was broken. All wiring is good now. These items did not fix the problem. I also checked the fuses on the back, but they look good. Anything else I should be looking at?
Thanks,

The KP-301 is a plywood, cornered, and handled Chorus. Crites offers a Chorus re-cap kit. You might want to replace the polyswitch in the tweeter protection circuit while you're at it.
Thanks, I was unaware of the polyswitch on the protection circuit.....I will certainly get this replaced. Also, we these being some 20 yrs old, the caps probably do need replacing.
Thanks again!

keep in mind that the K601 horn found in the KP301 is 90 degree horizontal, the K604 horn in the KP301 II is 60 degree. The driver and network change as well. I'd leave well enough alone unless you really want the narrower coverage for longer throw. I use mine on floor, sometimes on stands the wider coverage seems to mate up to the output of the woofer very well.
Thanks for the input. I have not received the 301's yet.....should get them later in the week. I was just asking based off of some research that seems to indicate folks' preference for the 301-II. Once I get these and play with them a bit, I'll have a better feel for their performance. I got these for garage/outside/tailgate duty. I have been using a pair of Quartet's for this, which sound very good, but are a pain to lug around......with no handles......and certainly are showing some wear.
Thanks!

I have just purchased a pair of KP 301's and was wondering if anyone has modified them any to improve the sound.....maybe swap the mid-horn with one that is in the KP 301-II's? Maybe a better question would be, is the 301-II version much better that the 301's? If so, could you mod the 301's and what specific changes would need to be made?
Thanks,
Hogfan

I need some input on these two speakers....I'm looking at buying a pair for outdoor use and want to make sure I'm buying the better speaker. I've never owned a pair from the KP line.....your input is appreciated.
Thanks,

What are the dimensions of this "baby LaScala"? Also, what size woofer are you using? If this is a smaller sized cabinet, are you using a stock crossover, or something modified? I have been thinking about building a small LaScala to use as a center speaker for HT, as I have space contraints not allowing for a regular size LS.
Thanks,
Hogfan

If I decided to build a smaller LS bass bin (on a 2/3's scale), with a 10" dirver, how would I determine what crossover to use? Is there a way of testing this to determine the crossover, or could I use an existing stock crossover....like a type AA? I am considering either a modified cornscala or a lil'scala as a center channel between my LS's.
It looks like a single-bin Cornscala would be the easier build for my situation.
Thanks,
Hogfan
-
Since I will be using the Cornscala (single) as a center between La Scala's, which have AA crossovers, which crossover type should I use in the Cornscala to give me the best match for the application? Would the ALK still be the best route?
Thanks,
Hogfan
-
What type of crossover is used in the Cornscala? Could I use/modify a AA crossover?
Thanks for your input.

Some additional info will help you sell these:
1) Pictures of the speakers.
2) What version are these.....1's or 2's? I believe one version brings more money than the other....not sure which...others can chime in.
3) Where are you located?
Good luck!

I ended up picking up a QSC GX3 amp, hooking it to the Sansui au-717 and I no longer have an issue with my system shutting down when powered with a generator. In addition, I find the QSC amp provides so much more headroom.....very satisfied with the new addition. It even sounds great at lower volume.
Thanks for all your feedback!

Ok, for what it is worth, I pushed the amp past the usual shutdown point inside my home, attached to the Quartet's......the amp stayed strong. So, does this tell me my problem is in the power supply (generator, or type of power it produces)? I went past the normal shut-off point a few clicks. That said, it looks like I either need to adjust the generator (if possible) or find another amp tolerable to my generator. Y'all agree? Anything else I should look at?
Thanks,

HogFan,
You could probably get by with any cheap solid state amp check out amps at parts Express. You can pick up any numbers for a 100 bucks or less, check the Bay.
I certainly do not understand the BLOW OUT test you are planning at home. All you will achieve is possibly blowing your speakers. What is the point of that? It is pretty obvious that your old Sansui amp is not very tollerant of the generator vltage pushing it or your speakers beyond their limit or clipping it serves no purpose.
JMO
I think the purpose of the home test is to see if I can push the amp to the same level where it shuts down when using the generator. If it doesn't shut down, then it would point to a power issue with generator setup. If it does, then it would indicate it is certainly an amp issue (with protection mode).
Thanks,
Hogfan

It's entirely possible the amp is working as designed. Play the system at home and see if you have the same issue. That will eliminate the power supply issues.
I'm tending to agree with Russ. Given that it shuts down the same with the other generator, yours probably isn't the problem (it would be weird if both were way below 60 Hz). Why not grab some hearing protectors (get everyone out of the house!), connect the speakers at home, and see if it does the same thing. That will answer the question.
Good idea....will give it a try (with ear plugs).
Thanks,
Hogfan

Correct, not experiencing any issues with anything else plugged into generator.
The Sansui does have a very thin power cord with 2 prongs at end.
Any recommendation for better/more tolerant amp?
-
I have no problem with the amp at home....it performs great, but I am not pushing it (not sure I could stand it) quite as hard.
The generator has the amp, cd player, tv and portable dish plugged into it. I borrowed a friends 3K watt honda generator late last season, and the amp shut down just the same as it did on the 2K watt generator.
The extension cord is a 15' contractor grade.....thick and heavy.
-
I would check the frequency of the AC coming out of the generator. If the generator is a non-inverter type, it's possible that the frequency is lower than the required 60 Hz. The lower the frequency, the less voltage headroom the amp's power transformer can provide (in addition to raising its operating temperature). So, if you're only getting say 55 Hz AC from the generator, you may not be getting enough voltage to allow the amp to deliver its full output. Pushing the amp into clipping is likely to engage the protective circuitry to prevent damage to the output transistors.
How would I go about checking this? Please be specific, as I am not very tech savy.
Thanks,
Hogfan

I picked up a QSC GX-3 a year or so back to run my KP-301's and could not be happier! It's part of my garage/neighborhood/tailgate setup. For me, the GX-3 sounds very close to my HK gear.....warm, yet clean. For the money, I don't think the GX-3 can be beat.
