I saw a Pioneer PL 200 and a Sanyo TP 1012 Turntable at my local goodwill store. I am thinking of picking up one of them.... 25.00 each. 
I am also thinking about a pair of B&W 570 speakers or Bozak 300 to create a music only system. The speakers are 59.99 a pair, from the goodwill store and maybe an AKAI AM 2400 stereo amplifier. What do you think?  
Can anyone tell me if the Golden Tube Preamp Sep1 with 1 tube will make a difference in a system?
