I remember reading somewhere that someone upgraded the opamps on the input board of this amplifier. I popped the cover off this amp and found 2 TL072 opamps. After looking up what was a drop in replacement for these I desided on using the Dexa supreme discrete opamp. After I wedged these things in (they are quite large compared to the chips they replaced) I must say after a few hours use the amp was completely transformed. The separation between instruments is much more profound and the decay of each note from those instruments can clearly be heard. All the small details in recordings are all coming through now. I can hear when a pianist is pressing the peddle on solo recordings that I didn’t hear before. Not sure what these opamps actually do in the amp, but sure glad I desided to change them.

I’d also like to give a shout-out to Parts Connexion for their help. After replying to a post about bad experiences with them. They reached out to me and worked with me to correct the issue.
