I noticed that that my NAD board components is is very closely reflected in NAD diagram, including the parts number especially the offset voltage and idle current VR's! Idle current adjust for L channel, same thing for R channel : -Turn-off power, unplug power cord, disconnected speakers, turn volume control down to minimum, -Series connect a 60W voltage same of amplifier power supply light bulb with the power cord as over current protection , -Connect a voltage meter across R disconnected LK39 LINK , -Turn R ohm to maximum resistance, -Turn-on power do Not connect speakers , -Turn R from maximum resistance and slowly down while watching the voltage across R, -Voltage across R should be between 0.
Offset voltage adjust for L channel, same thing for R channel : -Connect a voltage meter across E and ground, -Adjust R until get 0V on the meter -It may affect the idle current, re-adjust R for the idle current if needed. Turn-on power, make sure it's 0V between E and ground, connect speakers and play music, monitor the temperature on the output heatsink. Finally, disconnect the 60W light bulb, re-check above and minor adjustment may be needed. I posted earlier but did not get the reply.
In great need. User MoreCowbell over at Audiokarma. Look for it shortly posted to the library. Just curious if anybody has a scan for the owners manual, and the factory spec sheet.
Thanks for the great database! Please let me know if someone has it. I have both reel to reels. If not, do you know where I could get them? Hi, I just bought a Marantz PM DC amplifier and I couldn't find its manual or manuals anywhere, I guess it's preety hard to find, so I would appreciate if you would give me a helping hand. Or at least a model that uses the same transport. Mine has developed an issue with the take up reel.
Parts appear to still be available, but that transport looks like it could be a real adventure. I im really looking for these or info on various functions that the service manual here thx to whom uploaded that one! Hi,I need a service manual for the Kenwood KA Can you help me? Thanks Fernando. Few days ago I finished to renew my Ka I own many other amps - 2x KA, had many KA, but this one seems to sound better. It was thrown away after two attempt to service it, so I had to renew everything and I also added a zobel network.
Hi Robert, Thank you very much for the information, and I look forward to the launch. I feel bad language in English. Hello I am unable to open the service manual. I get an error message about "bad encrypt dictionary" Anyone else with the same problem? Hi- Saw your comment. Tried to open the SX manual and got a similar error message. Problem seems to be with multiple Pioneer models. Haven't figured out a solution yet.
Any luck in your attempts? I am looking for specific model of Technics. Both are from 's sorts. Gallery Requests Search. Submitted by DM2a68 on January 10th, in Requests.
