Questions for the Harris amp experts.
Which channel/model is best for 2 meter use? How much and what type of
modifications are needed?

Tom
I supplied those amps to Marshal to be shipped to HI a couple years ago.
Maybe I can help.
Like the others said, count the blinks and determine the error code.
If it is code 3, message me directly. I can help you determine which modules
need to
be replaced. I have some tuned and tested 222 ¼ modules on hand. We can
figure out
how to get you the repair parts you need.
It's important keep HI on the moon.
