Hi Scotteboy. Just wanted to say that the Marantz 2270 you restored and is now in my possession is awesome. I also own a Scott LK72 tube amp and am amazed how this 40 year old solid state classic sounds so "tube like." Anyone looking to have their classic Marantz restored would do well to contact you. BTW, I'm RightDeaf here but AKA Mayberryismyhome. Best to you.
