Very carefully lgg the glue seal between the 2-pole purity convergence magnets PCMthe band and the spacer. Page 6 Circuit Board Foil Repair Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil to separate from or “lift-off” the board. Page 35 – 35 Do not connect the test fixture ground strap to any heat sink in this receiver. Color purity adjustments should only be attempted by qualified personnel.
