I have an old technics integrated amp with a built in Phono stage that I no longer use. Currently im using a Roksan Caspian m1 amp. Can I use my old technics as a Phono pre into my roksan. The technics doesn't have a pre out. So if i have turntable into Phono on technics..volume turned down, tape out into aux on caspian and use caspian volume for control. Will this work or do I run risk of blowing my roksan?
