pierceb Posted February 21, 2006 Share Posted February 21, 2006 I have an HK630 that has the signature scratchy volume/balance pots and switches as well as some burned out light bulbs. I was wondering if someone knows the part number(s) for the light bulbs as well as a good contact cleaner to use for the pots and switches. I believe one can get both bulbs and cleaner at partsexpress?? I know there have been some good threads on cleaning and maintain the HKx30 receivers in the past, but the search function on this board is useless, and trying to find them has given me a headache. If anyone has a link to these threads, it would be greatly appreciated if you could reply. -PB Quote Link to comment Share on other sites More sharing options...

wuzzzer Posted February 21, 2006 Share Posted February 21, 2006 DeOxit is the cleaner you'll want to use. Available at Radio Shack. Quote Link to comment Share on other sites More sharing options...
pierceb Posted February 21, 2006 Author Share Posted February 21, 2006 Thanks Rick and Mark. Will these cleaners work OK in the tuner section as well? I thought I read somewhere a long time ago that the tuner sections need a different cleaner. I could be wrong though. -PB Quote Link to comment Share on other sites More sharing options...
DRBILL Posted February 22, 2006 Share Posted February 22, 2006 If you still have them, take the bulbs with you to Radio Shack. They have a wide inventory of the usual bulbs. DRBILL Quote Link to comment Share on other sites More sharing options...
intotubes Posted February 22, 2006 Share Posted February 22, 2006 I just replaced the bulbs in my HK 730. They were fuse type 8 volt 300 ma. They look like little 1/4" fuses. Mine took 6 including the FM meter. Agree with the deoxit. I took the reflector for the bulbs off first to gain access to the switches and bulbs.

pierceb Posted February 24, 2006 Author Share Posted February 24, 2006 Well, unfortunately Radio Shack seems to have called it day up here in Canada, but I did find another brand of contact cleaner. I tried it and the scratchiness in the pots and switches are pretty well gone. Not sure if it works as well as DeoxIT, but I'll try it for a while. As far as the light bulbs are concerned, I need a light for the "STEREO" indicator (at least I think I do). This light is like not the tubular, fuse-like, bulbs that exists behind the panel. It looks more like an LED light (I know it is not LED though). Does anyone know the type of bulb required (i.e wattage, amperage), as it does not say anything on the bulb itself. The STEREO indicator worked when I first purchased the 630, but it doen't work anymore. All the connections preceding the light appear to be intact, and the filaments in the bulb don't appear to be broken, but for some reason the light doesn't work anymore. Maybe there is another culprit? -PB Quote Link to comment Share on other sites More sharing options...
filmboydoug Posted February 24, 2006 Share Posted February 24, 2006 Keep that out of your tuner gangs! Use compressed air. Quote Link to comment Share on other sites More sharing options...
Seadog Posted February 24, 2006 Share Posted February 24, 2006 The Rat Shack tuner cleaner will kill the sensitivity of the tuner! Don't use it or anything similar to clean the tuner (personal experience here!). If you must clean the tuner, "Blow Off" Contact Cleaner works very well (made by AVW). This spray will also remove Rat Shack cleaner from the tuner and restore the sensitivity (again, personal experience with an HK 430 [:$]).

Doc Robin Posted February 24, 2006 Share Posted February 24, 2006 What is a good price for a HK630? I just found out that one of the guys at work has one and is think of selling it. He is only using it as a tuner for an Adcom amp that is driving his '82 Cornwalls. Bill Quote Link to comment Share on other sites More sharing options...
pierceb Posted February 25, 2006 Author Share Posted February 25, 2006 Thanks for the warning about using this stuff in the tuner section. I thought I remembered a similar warning in a previous post, so I left my tuner section alone. Bill, as far as price for a 630 goes, I think they range in price from about 50 to a 100 bucks, of course depending on condition. I paid 120 bucks for mine, but it has a factory wooden case and everything is in immaculate condition (except for the STEREO indicator light of course[]). -PB Quote Link to comment Share on other sites More sharing options...
intotubes Posted February 28, 2006 Share Posted February 28, 2006 Here's the tech manual with schematics. Maybe it'll tell you. http://manuals.harman.com/hk/Service%20Manual/hk630%20sm.pdf Quote Link to comment Share on other sites More sharing options...
mbajner Posted February 28, 2006 Share Posted February 28, 2006 I had an HK630 receiver bought it new when I was in High School it too had the scratchy volume noise then the amp started making a humming noise too so, threw it out with the garbage one weekend not worth fixing for the cost to fix it it was a great receiver in its day but one has to move on to better things Quote Link to comment Share on other sites More sharing options...
pierceb Posted February 28, 2006 Author Share Posted February 28, 2006 Thanks Mark, that's exactly what I needed. Looks like I need a 14V, 80mA bulb. I'll save that link somewhere safe. -PB Quote Link to comment Share on other sites More sharing options...
intotubes Posted February 28, 2006 Share Posted February 28, 2006 Do better than that. Save the pdf file on your hard drive and then print it out and keep a copy with your manuals. That's what I did for my 730. There's no telling how long Harman Kardon will keep them up on their website. Quote Link to comment Share on other sites More sharing options...
