Chimpie Posted March 17, 2009 Report Share Posted March 17, 2009 Hi guys, I've got an AKG K1000 at Alex. I bought it second hand from HeadFi, but unfortunatelt one of the drivers is not working properly. So I'll need to find a new pair of drivers! Any idea whether AKG can still provide them? I've tried mailing them, no response yet. I'll give them a call later this week, but if you guys can confirm they don't have it in stock anymore, I won't bother and save the telephone costs (I live in the Netherlands). One other guy at AKG told me I would need new printed boards as well, if I own an older system. Anyone heard about this?? Thanks for the help, guys! PS: Talked to Craig and he's working on a hybrid class a amp for the K1000. He says it'll outperform the FirstWatt F1!! Quote Link to comment Share on other sites More sharing options...

n_maher Posted March 17, 2009 Report Share Posted March 17, 2009 Last I heard AKG was saying that they were all gone. Quote Link to comment Share on other sites More sharing options...

Blackmore Posted March 17, 2009 Report Share Posted March 17, 2009 For all, who need some spare parts, try this company in Germany, I bought K1000 and K340 drivers/parts from them, great service, ladys name Evelyn Nagy, mail: [email protected] If one driver is dead, you need 2 new matched and not one to complete your K1000. Actually you can send your K1000 and they will repair for you, did it as well. rw soundsystem Breslauer Str. 8 74613 Ohringen Tel 07941 64779 0 Fax 07941 64779 19 [email protected] [url=http://www.rw-soundsystem.de]rw soundsystem - die profis f Quote Link to comment Share on other sites More sharing options...
Chimpie Posted March 17, 2009 Author Report Share Posted March 17, 2009 Thanks for your help, Sergei. I'll send them an email now! Quote Link to comment Share on other sites More sharing options...
statica Posted June 25, 2010 Report Share Posted June 25, 2010 Thanks for the advise! I got in touch with Evelyn and looks like the parts I need for my K-1000 they have!!! EX! Does anyone know how to replace the LEVER (the one that locks the cup/case)? That's one of the parts that I need. Quote Link to comment Share on other sites More sharing options...
swt61 Posted June 25, 2010 Report Share Posted June 25, 2010 Maybe Fitz will join in here. He has my K1000 ATM for a re-cable, and I'm sure he has an idea how to replace the locking lever. Quote Link to comment Share on other sites More sharing options...
faust3d Posted June 25, 2010 Report Share Posted June 25, 2010 yay......... the F1 wasn't even meant to drive dynamic drivers, so actually making an amp that was designed to do this would be a huge improvement. You lost me here what was it made to drive, stats? It is well suited to sensitive full-range drivers such as Lowther or Fostex, and allows easy use of parallel loading networks to tailor the driver response. - from FistWatt site.

Fitz Posted June 25, 2010 Report Share Posted June 25, 2010 Maybe Fitz will join in here. He has my K1000 ATM for a re-cable, and I'm sure he has an idea how to replace the locking lever. I've never needed to replace them, as mine work fine and nobody has ever asked me to do it while performing other repairs, but I can look at it on yours to note the process if you want. Perhaps I could also go ahead and make that video on the disassembly/reassembly of the grilles that I've been meaning to do, as well. Actually I have a lot of AKG service videos I've been wanting to make, dunno when I'm ever gonna get around to it. I'm hoping to finally get your K1000 done this weekend. We hardly had anything going on at work before, but now all of a sudden lately it's gotten crazy busy. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted June 25, 2010 Report Share Posted June 25, 2010 You lost me here what was it made to drive, stats? - from FistWatt site. perhaps traditional dynamic drivers would have been better. You looked at the right page though, the explanation is right about the paragraph you excised: "It is a power trans-conductance amplifier (or power current source, if you like), replicating an input voltage into an output current. A regular amplifier sends output voltage to the loudspeaker. This is not that kind of amplifier. This amplifier ignores the elements in series with the load circuit, including back-emf, wire resistance, inductance and such, and creates voice coil acceleration in direct proportion to the input signal." Has anyone here heard (or considered the upgrades) the F1J? Quote Link to comment Share on other sites More sharing options...
Fitz Posted June 25, 2010 Report Share Posted June 25, 2010 Which in translation means it does funny things to the sound of most speakers (and headphones), because they're expecting a voltage source, not a current source. Quote Link to comment Share on other sites More sharing options...
swt61 Posted June 26, 2010 Report Share Posted June 26, 2010 My levers work fine Ryan, no need to do more than necessary IMO. I'm hoping to finally get your K1000 done this weekend. Awesome! Quote Link to comment Share on other sites More sharing options...
mrarroyo Posted June 26, 2010 Report Share Posted June 26, 2010 All I know is that Ryan fixed two yes two K1000 for me and they sound awesome! One of the K1000 had a driver from hell in which Ryan performed micro-surgery and brought it back to life. Thanks again. Quote Link to comment Share on other sites More sharing options...

Has anyone here heard (or considered the upgrades) the F1J? You know I read this as well but you like to post these categorical sarcastic one-liners that just sound wrong.... I heard it with Fostex TL speakers and it sounds awesome, but I on't know how it would sound with K1000. On the other hand if you hook it up to orthodynamic headphones I bet it will be great.

mypasswordis Posted June 26, 2010 Report Share Posted June 26, 2010 On the K1000 the F1 is not a current source, output impedance is only 80 ohms vs. the 120 ohms driver (and that's what, at 1kHz or something? the impedance at high frequencies being even greater). There seems to be more than a few headphone amps with (sometimes switchable) high output impedances like the looooooong amp and Silver Ghost. Can't say I'm a fan of the sound, but maybe I'm just not used to it. Quote Link to comment Share on other sites More sharing options...
