it is probably the right amp as I disconnected the ICs totally and swapped speaker cables and noise shifted to the left amp.
Doesn't sound the right amp to me. Sounds like maybe a bad speaker cable termination. The speaker cable that started out connected to the right channel and then was moved to the left channel. You said the static "shifted to the left channel".
If the right channel amp was the problem, then after you switched the speaker cables the static would still be in the right channel.
