Hello, This for restoration after repair attempts by incompetent people this Marantz 1300DC.
The problems presented are both functional, totally changed and with several errors in the repair channels (not delivered fully functional) but I managed to recover one channel some time ago.
1) Both channels will be redone PCBs, restored the circuits, the problems of Bias and derivatives
2) Phono stage also will be revised due to a heating problem that simply they put some aluminum heatsinks to remedy the situation.
3) all plates will be reviewed and the plating will be repaired and repainted to remove signs of rust.
4) electrolytic capacitors and worn parts are replaced.
When I return from vacations until the end of September in the week-end will be redone.
PS: I do not normally do restorations even dedicate myself to the audio, however this problem was given to me in hand and will be solved past few years.
The final price is not set (depends on the hours and materials costs) but not less than 300 and just for recreation)
