hello all!
my flat mate is getting a bit depressed without music: his denon pma 680 r amp quit working after a party some days ago.
i tried to find the reason of the silence and found that the primary coil of the transformer was burnt. i din't know that could even happen, but there is no doubt.
we wrote a mail to denon austria and they told us a new transformer would cost 170 euros
. that seems quite much to me!
we decided to find another solution. but: i din't find any place where to find a technical manual of this amp.
the people at denon were friendly enough to tell us that the amp needs about +50 - 0 - 50 volts of supply voltage (power supply out after rectifier and caps) and more than 200 watts.
i do not believe these suggestion is very accurate...
i don't want to buy a transformer and then ruin his amp with over-voltage
. it is a remote controlled amp with lots of sensitive integrated circuits insinde, i guess...
does anybody of you own such an amp?
would it be possible to measure the secondary voltage?
do you know any other way to find out the data of the transformer?
thank you very much!
