ricktate Posted September 6, 2005 Share Posted September 6, 2005 When you take a reciever in for repair or tune up do they go through the whole thing or just fix whats not working? I got several HKs i would like tuned up they seem to work fine except one goes in and out of stereo mode.I just got a HK930 and it has a little more noise when volume is turned off ..more than the HK430.Anyone work at a repair shop?

colterphoto1 Posted September 6, 2005 Share Posted September 6, 2005 My 430 has a wicked hum when it first come up to power, it goes away quickly, is this normal? I leave volume down the 20 secs or so until it dissipates. Michael Quote Link to comment Share on other sites More sharing options...
ricktate Posted September 6, 2005 Author Share Posted September 6, 2005 I turn all mine on like Andy..HDBR..said to...power up with speakers off for atleast a minute then turn speakers on...then to turn off ...turn speakers off for a minute then power off.None of my 430s hum at all and with volume all the way down very quiet.Rick Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted September 6, 2005 Share Posted September 6, 2005 Why is that procedure recommended, do the power supplies spike or thump on some units, blowing speakers? My hum is just at the unit itself, very low level, just while it powers up. Perhaps this could be damaging to the speakers? Michael Quote Link to comment Share on other sites More sharing options...
Spkrdctr Posted September 6, 2005 Share Posted September 6, 2005 Please be careful with taking your gear in to be "tuned up". One, they will not touch a working unit as they do not want to break it. They will place it in the corner, wait 5 days and tell you to come in an pick it up, with a nice tuneup" fee. They might clean it up for you and blow out some dust with an air compressor. That is it. The repair techs have to fix this stuff as quickly as possible to feed their family. Now if it is broken, they will fix what is broken. Please do not waste money going for a tuneup. If you really need a tuneup, it would involve replacing caps in your system that are old, and yes it will make it sound better. Getting someone to actually do this though is another story. Unless the gear is vintage that you really want to keep, after 12 or 15 years, just dump it in the trash and buy new. For the older good vintage stuff, you need to get someone who likes vintage audio, and will take the time it requires to fix it correctly. I would do it for you, but it takes way too long and I lose money on each one! Quote Link to comment Share on other sites More sharing options...

ricktate Posted September 7, 2005 Author Share Posted September 7, 2005 Thanks guys that is what i figured would happen they wont fix it if it not broke.The 930 works good so i will just use it see what happens but i didnt want the tech. to rebuild it just adjust all the adjustable stuff in there and it looks like there is a lot of it in a 930 the HK430 does not have all the adjustable things in it maybe thats why it is so quiet huh.Rick Quote Link to comment Share on other sites More sharing options...
MrMcGoo Posted September 7, 2005 Share Posted September 7, 2005 Good advice; if it isn't broken don't fix it. Bill Quote Link to comment Share on other sites More sharing options...
RichardP Posted September 7, 2005 Share Posted September 7, 2005 On a tangent, be thankful if you are lucky to live near an electronics repair shop. In my town of 40,000, there are none, whatsoever. The nearest repair facility is 70 miles away. I read in a recent Sound & Vision article that since about 1990, the number of electronic repair shops in the US has diminished from about 20,000 to 7,000, as more and more electronics are intended as disposible, rather than repairable.
