    My grandfather gave me his old quadraphonic 8 track player and I recently took it to work to power a set of Kenwood 3 way floorstanders I found in an abandoned area of the building. When I hooked everything up it worked but sounded very quiet, then all of a sudden the right channel gets really...

    Hey all. Thanks for all the help on the 140 and 170dc, next from the closet is a 1180dc. I have unboxed it, tested it, and removed the covers. The unit plays well and all controls operate. This unit uses boards with pins that are prone to failure and someone before has solder bridged all the...

    Marantz 170dc help/advice/guidance Need help after my mistake!

    Hey all, The 140 turned out well with all the help on AK, a few hiccups, but all is good. I also have a 170dc that I would like to refresh. I started with PN00 and replaced the electrolytic caps, I had the exact replacements for all except CN04, which is a 10uf 63v. I put a 10uf 100v in its...

    Speaker re-cap

    How do you know when you should re-cap a speaker cabinet? Even though the speakers are old, If the capacitance measures out, should it still be replaced?

    Pioneer CS-88a + Sansui 9090DB Troubleshooting

    Hi AK community. I've been slowly rehabbing the aforementioned equipment (Pioneer CS-88a Speakers + Sansui 9090DB receiver) over the past year and, after making some headway, I seem to have met my match.

    NPEs for cross-over recap

    I just picked up set of Kappa 8s and I am going to do a partial re-cap, replacing all the NPEs. I've used Mundorf E-caps when I re-capped my RSIIIbs, RS5bs and Kappa 6s. Very happy with the results but here is my dilemma. I need much larger NPEs for the woofer section of the Kappa 8s and I can...

    Goliath II sub sounds "gravelly"

    I have a Goliath II sub that sounds gravelly or scratchy. It has been re foamed but I don't think it has been re capped. Is it just a bad foam job or would some new caps clean up the audio? Or is the driver toast?

    SX-950 -- Noisy phono stage (AWF-011) after re-cap

    Hi all -- first, a thanks to everyone posting information about these amps. My father had one while I was growing up and was very attached to it and the sound. It's nice to know I'm not alone in loving these old receivers and that there is perhaps more to them than just nostalgia. I've just...

    Sansui 9090 re-cap gone bad

    My Sansui 9090 (non DB) would not come out of protection mode, so I did some research on this site and from the help of past posts it wisely lead me to look at the F2436 driver circuit board. At location R30 I found a bad/open fusible resistor, so I replaced it along with 11 other resistors, 4...

    Speaker caps from Mouser?

    The reason for the question is that most parts suppliers levy substantial charges for international postage - Mouser is an exception (no intended plug for the business). If anyone has experience with this, I would appreciate it if you could let me know if any of the caps in the Mouser product...
