Hey how you doing my name is Steve I was reading your blog on the kenrich eagle 500 I've got a few questions maybe you could answer for me! I was using the amplifier and having no issues I shut it off and went to use it the next day turned it on everything as usual normal until I went to key it up and it will not key up anymore. I can you tell me where I can start I'm trying to figure this out. Thank you Steve.
