HF-81 with CDs

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

When I listen to CDs through my Eico HF-81, I hear severe HF distortions and excessive hiss and sibilance to the extent that I have to turn HF controls almost completely counterclockwise.

Vinyl records sound fine (I recently replaced old Mullard 12AX7 tubes of the phono pre-amp that produced hum with two NOS Mullard 12AX7 tubes and it is quiet now).

I don't have a tube tester but what should I check? Should I try to replace other tubes or look elsewhere (cables, resistors, etc.)?

I don't have pictures right now.

I have other amps each of which sounds much better than Eico when I want to listen to CDs, but I am just curious...
