Test record to set gain on Rock Ola 477

[prime]

Hi , the cartridge that came with my unit was damaged so ive replaced it. When looking at the service manual it states to set gain use the Rock Ola test record. Im not sure if this is still available. Is this record needed or can i use something else?

Hi Pete,
I doubt you'll find the record-- but try looking for it-- otherwise I use a mono voice, only, record and compare the channels-- Ron Rich
