Hi All,
Recently, one channel of my relatively new modified marantz M7 preamp broke. I wondered if anyone has a schematic on this amp made by musical angel, which was frequently listed in Ebay. I have a jpeg which is very hard to read and I could not get the supplier to put up a better one.
Any suggestion on modding this amp for better performance while I am repairing it.
It started out very static-ky and then no more sound, just some hum. on the left channel.
Any help is appreciated.

Is there a chance that you could draw out the schematic and list the tubes ? I can't make out the schematic you posted.

Unfortunately, that is all they gave me on the ebay listing. I know the tube should be 12AX7 and the rectifier tube should be the standard type. I would try to trace that out when I have time. it would be at least a couple days before I can find time to get to it.
I found this one from a website and I wondered if it is similar.
