Hi, In this sale I have a barely used LK-800A linear amplifier made by Amp Supply. This amplifier does not come with the optional Power Pack external transformer, however it is fully functional with its internal transformer. See my other sale for an LK-800A that comes with the power pack. This amplifier is very heavy. The amplifier works great. It has 3ea 3CX800A7 tubes installed and each tube is rated at 750W. I will also be saleing off 3 brand new 3CX800A7 tubes that are brand new from Eimac and a second LK-800A amplifier with power pack. I would prefer local pickup on this since it is so heavy. Send me a message if you want it shipped before offerding so that we can work out the charges for that.
