Graaf Amplifiers Factory closed down

Hi , Graaf factory will be reopened from Audio Analogue.

Mariani will work with them .

They stard the new production with a cd player and maybe with a Gm 50 integrated.

No more news from Italy.

I'm a Graaf lovers and i'l take care about my Gm 20 , Gm 70 , Gm 13.5 and Gm 50 .

Looks like Graaf is back. I own the Modena, GM200 and soon the new GM400

Does ANYONE have a schematic for a Graaf 13.5B MkII preamp?   I need some schematic with voltages for a repair.   Willing to pay for even a copy handsomely.   David
