EQUIPMENT HISTORY:
Everything I am describing below is IMPORTANT, read it please!
This amplifier is part of my “collection” of all things audio, both professional and consumer gear. I personally don’t mind a decent NAD piece of gear and actually had three of these 3240PE’s, this particular unit was a “to be looked at” as it is NOT WORKING CORRECTLY – see the FULL details below.
These 3240PE amplifiers surprise many. They use an amplifier design which NAD called Power Envelope Technology and this design results in an amplifier that easily produces far greater audio output than the listener could be expecting.
This amplifier is designed to supply 40W Audio power (RMS) per channel into a “normal” 8 Ohm loudspeaker system but on loud passages/peaks, this amplifier easily delivers 80W output on each channel – the idea being that when listening to music with a wide (demanding) dynamic range, this amplifier will sound great no matter if the audio is of a low level or suddenly jumps up in level considerably, the 3240PE takes it all in its stride. Other amplifiers, when pushed hard, will spit the dummy and sound absolutely horrible (distortion).
Actually reference to the NAD technical information shows these amplifiers can produce up to 160W per channel (for short periods – similar to Peak Power) if called for.
I have over the years collected together a LOT of quality audio equipment due to my business activities in pro audio post production and general electronics but the day has finally arrived!
Well, my wife says “for goodness sake, get rid of that mountain of gear” so them’s my orders … out they all go.
This equipment does have issues, and it is extremely important that the complete description is read in full.
THE CONDITION OF THIS EQUIPMENT IS CLEARLY STATED BELOW, BOTH COSMETICALLY AND ELECTRICALLY
There is no warranty, there are no returns – but I am very thorough and do not “gloss over” any issues I might discover!

Even if the new owner doesn’t feel up to repairing or having this equipment repaired, it’s is still a great source of some very hard to find parts.

COSMETIC CONDITION:
First glance, not bad at all in fact it is in pretty good condition, cosmetically.
Front panel is clean, all lettering (silk screen) is undamaged and perfectly readable.
Knobs are all present and clean
Side panels are clean with only the very lightest of scratching, none of which breaks through the outer coating
Top panel is clean, with only a couple of very light marks – not scratched.
NO signs of a “drop” in other words, no bent case or frame.
One speaker terminal/binding has the plastic top section missing! You can still use this terminal though, or just use the speaker outputs B
NO case screws are missing.
All feet are present
Base panel is fine, no rust observed (I have seen this before, rust underneath indicates it has been in a flood or suffered previous water damage – serious problems!) This unit has not seen water!.

Next I take a look inside …
The first thing I noticed is the large empty area inside! Strange this one, this model never had
