Marantz 2270


Bought at the end of 2016 a Marantz 2270 from Ebay.

The owner at that moment found the receiver in the basement of his grandfather as he told us and put it on Ebay.
I bought it for 435,- euro's and picked up in Germany.
At home I did some investigation because it did not work at all......

What did i found:
Powerswitch contacts where completely burned away.
The dial lights where defective included the stereo indicator.
AM tuner defective
Found strange wirering between poweramps , relais and outlets.
FM signal indicators gave allmost nothing though the reception was sensitive enough.
O yeah, the wooden case was painted...

All these items where repaired with a minimum of costs. And even the wooden case looks perfect after restoring.
Then .... measurements:
Power output more then 80 Watts RMS per channel both channels driven. Distortion less then 0.4% at 70W .
So it still meet the specs I believe.

I Use a set of Bowers & Wilkins DM2a's which are sounding marvelous in combination of this 2270 who was build in 1972 !

Background information: in the very past I worked at the former Dutch import company of Marantz (Amroh in Muiden, the Netherlands) and later on at the service departement of Grundig Netherlands in Weesp.
So, all the knowledge, skills and equipment for restoring audio equipment is available.

If someone needs help you can always contact me.

I sold a beloved 2285 (just a bit more output at 85 watts/channel) in 2009 due to hardship for much less that that....the 2285 was in perfect operation, even had the original box and owners manual for it...my loss, another's gain.  Enjoy your 'new' purchase!
Hello Quincy, thanks!
Also I read some issues about speaker cables.
There are lots of people who claimed to hear the difference......
I've made a study about the cables and found that it is impossible to hear the difference between 2,5mm2 and 1mm2 wires when used in a normal house room with an output of 10 Watts. 
With 4-pole parameters calculation you can easely check this out.
So, just use a common simple cable but watch the polarity.
