Picked up a broken Marantz 2270 yesterday -- multi-voltage unit in a wood case. The case looks like every other Marantz 22XX case, except it is Vinyl Veneered .... Anyone ever seen one before ?? Also, the power cord is has a three pronged grounded end on it. Looks original. I'll take some pics of it in a bit.....
Anyone familiar with these multi-voltage units ? When I got the receiver, there was NO output and neither the FM or AM worked at all (tuning meter and signal strength meters do not move) There are 4 internal fuses next to the power supply board - one has 0 volts across it, two have 35V and one has 120v.....No the fuse is not blown...
With the help of Marantz Guru Tom aka CATRAFTER, he determined one of the power amp boards is bad, causing it to go into protection mode. So, I clipped the wire from the bad board to the protection relay and viola - the receiver started working (through headphones) along with the tuner section (well working from the good channel) Still no voltage on that 4th fuse.....hmm.
Does anyone know what the 4th fuse is for ? I was thinking maybe when you wire the receiver for a different country it utilizes that circuit ??? Curious.... Dan
