In that case your phono preamp is cheap junk. Send it to the recycling center.

Get one of these.

The Audiotechnica is on sale for $43, and it will be fine.

thanks...will try better one

also if you know of anyone interested in trading NAD 1600 for my 917...i would be interested. the 917 has more video bells and whistles than i need ...but is GREAT preamp...and excellent condition...all books and remotes also
