Mikepaul, From your last post it appears you think you need a mono cartridge to play your mono records. Not true! A regular stereo cartridge can play mono records just fine. The output from your stereo cartridge will have essentially the same signal in each channel and at the same level. The reason mono cartridges have become popular recently is that they can sound better playing a mono LP than a stereo cartridge. A mono cartridge can also reduce noise due to record wear. Most importantly, playing a mono record with a stereo cartridge is totally safe. You are not risking damage to either the record or cartridge by using a stereo cartridge.
