small red lights flash on my Nakamichi PA-7


First time on this forum.
Just bought a used Nakamichi PA-7 power amp. Everything seems fine, music sounds great, but sometimes the small red lights on the front of the amp blink or stay on for a second. What does this mean? Any suggestions on where/how to find an owners manual for this unit.
Thanks

Need to do their best your Wolfness.LOL Are you related to Hugo Wolf, the one whose buried about 20 ft from Schubert ?

Why don't you just borrow over and ask good ol' Hugo yourself? ;-)

Don't take offense, Schubert, I couldn't help myself. It's been a tough week and I'm getting a little punchy!

Wolf, I'm not disagreeing with your experience, as I too, have had experience with the Nak amp, and 200 watt Adcom amps with this type of LED indicator. It will be very easy for these LED's to blink when using speakers with an 85-86db sensitivity in a larger room, playing music with a wide dynamic range moderately loud. I'm sure you realize the amp/speaker relationship is logarithmic, and not linear. A very slight increase in a dynamic peak will require quite a bit more amplifier power.

Here is an article about this amp using different speakers. Check out the next to last paragraph.

Joe, download the manual for GFA-5500 here, and read the section "Instantaneous Distortion Alert LED's". This is basically what a manual for the PA-7 would say.

No sweat Swamp , if you dish it out need to take it too. Life is hard.Wolf really is buried in Vienna right next to Brahms who is
buried right next to Schubert

Just a comment Wolf, didn't think you were.
THANKS TO EVERYONE, some very interesting info for me to use. The speakers are Vienna Acoustics' Baby Grands, my brother-in-law didn't use and sold them to me.
Any ideas on where/how to find operating manuals for the Nakamichi PA-7 and CA-5.
I was playing very loud Highlands Cathedral, a combination of brass, bagpipes and organ.
Again thanks to everyone.
