William, thanks for your input. I'm just starting my tube adventure and have my work cut out for me. I've always had the mindset to buy the best product I can afford,not wanting to have to replace it later. I'm beginning to think that is not the case when trying to get started with this project as I simply have too many choices with far too little knowledge. The one thing I'm positive about is coming to this forum for help. Thanks again!
Mike
