Nash 400 problems

John Knight · Post by **John Knight** » 2 Apr 2001 9:37 am

Here are the symptoms; distortion, sound cutting out, loss of volumn. Does any of this sound fimilar to you other 400 users. What are the cures??????? It seems that a slight drop fixed the problems but that means something is loose inside.

John,
Unplug the connector that comes from the reverb can and plugs into the chassis(under the bottom)it's a white connector.
check it to see if it's spread apart too much,
if so CAREFULLY close the little barrels a TINY bit, spray some cleaner on it and plug it back.most of the time ,just unplugging,cleaning and re-plug does the trick
This usually is where the problem lies,
hope it helps, if not ,feel free to email me.

Thanks Kenny, I read about that on John Lemay's web site. I think the problem is on the board or in the speaker connection and here is why, During the last 3 sets last Sat. I unpluged the reverb altogether. I was using my Profex II so it was not needed. Problems we're still there.

Check the POWER AMP IN Jack on the back. I'd bet the "normal through" contact is dirty. This is another common problem with the Nashville.

The next time it happens, plug a jumper cable from the PREAMP OUT to the POWER AMP IN and see if this fixes it. If it does, the "normal thru" contact internally on the jack is dirty. Some times just plugging in and out several times will fix the problem, other times it will take contact cleaner to fix it.

TRy another speaker. If its ok then check
the BW basket. Try rotating the basket to the
next slot.

The first suggestion that I always offer is the same that Jack Stoner posted, however, you can also use a shielded cable to close the loop between the PRE EQ PATCH "IN" and "OUT" jacks as the "IN" jack is a switching jack just as the POWER AMP IN is. The jack may not be functioning properly.

If you need clarification on this, give me a call at 1-877-732-8391.

Thanks for all the suggestions. Played the amp last night I did not get any of the distortion or power/signal cuts but I did get some nasty high pitched overtones. Could this be connected with the reverb unit. I did reconnect it???? I guess I disconnect it and see what I get, DAH!!!!!!!!!!!

Jack please close this thread. Speaker needs to be repaired.

Thanks
