It is recommended that the HER602 diodes be replaced with the MUR820 (was Motorola, now ON Semiconductors), and that the 470 uF capacitors be upgraded to 1000 uF high-frequency types. Loud pops, particularly in the phono section when the tubes are moved indicates broken foil on the circuit board.

The Schottky SB560s are excellent at low PSU voltages if you add a bleeder across the secondaries to prevent transformer ringing. I tried MUR860-types (never MUR 860 itself), but the Schottkys sounded better to me. Worst in GC application were some FRED diodes, which admittedly sound better at higher voltages.
