Thanks NOSValves and Speakerfritz, [Y] I have got the part number (159-019) for powertransformer from the service manual. But I am not sure how to obtain the tech specs of the transformer. The service manual contains the specs for caps and resistors' but no information regarding ratings of power transformer. Do you guys have any documents which contain the part numbers and the corresponding specification? Regards, Prateek

I am trying to restore McIntosh C-11 and C-22 preamps. I have got the schematics for the job but they do not mention the voltage and power ratings of the power transformers. I humbly request the exixting owners of these awesome vintage preamps to please help me out. Please provide me with the details of power transformers on these two preamps. I hope you guys can make them sing again.[] Thanking you all.
