I just bought some flea elements Pioneer SA608 amp, Tuner TX608, platinum K7 CTF600, all for € 20. Cleaning the pots and switch, replacing belts, tuning and decoupling of inters, everything works great.
Remained the CD player SONY CDP-M19, including listening, so I jumped at the following totorial (Thanks by the way) to adjust the lens and is nickel. Good material very strong.
