Francesco Izzo

Hello to all from Italy ! My name is Frank and I am a DIY tube stuff designer and repairer and I hope to get help from this community because I have tried to search and contact every where and every site related to CARVER products but invane ... In short I have the opportunity to get my hands on a not working but in very good condition SUNFIRE CLASSIC TUBE PREAMP but I can't find the schematic, so I am asking if any of you can suggest where to find it ( a scan or by download) ... obviously I can Pay for this but It seems that this schematic is not available on this site either ! Can anyone help me ? Thank you very much in advance !
