Marantz PMD222 Mic input noise modification

["Adam Liberman" adam5532]

Hi,

If anyone is still using a Marantz PMD222 cassette recorder (although
I hope not!), we have decided to make public our previously private
modification that reduces the noise on the XLR mic input by up to
Message: 10dB. 
Subject: We no longer repair Marantz cassette recorders, and can not
offer assistance with this, but the mod includes complete
instructions, parts list, and schematic and board layout for that area
of the circuit. It is available for download at:

Thanks,
