Here's the situation. I am trying to connect a JVC L-E600 from the mid-eighties to a fairly new Sony STR-DE675. I have tried to connect through several inputs, including AUX, CD, VIDEO1, and even went as far as patching it through my TV. The problem is I have to max out the volume on the reciever to get a "medium" sound level, and even at that it is only twitchy highs and absolutely no bass. I was wondering if the problems lies in the fact the reciever doesn't have a PHONO input. I don't know if that would make a difference. Any suggestions would be appreciated.
