[QUOTE="Sachin D, post: 1132054, member: 26200"] Hi, Thank you all for the advice, we are -planning to go with below spec for power transformer. Primary winding: 0 - 220 - 240v Secondary windings: HT: 380 - 0 - 380v, 200mA LT 6v: 3.15 - 0 - 3.15v 4A LT 6v: 3.15 - 0 - 3.15v 4A LT 5v: 0 5v, 3A Now you can have one LT 6V winding per channel! Going thorough above and discussing with winder, we are confused on "LT 6v: 3.15 - 0 - 3.15v 4A" as we don't see any 3.15vollts any where on the diagram. We could see 430V on ST60 Diagram as suggested by Charles, however on Power Transformer its mentioned 380 - 0 - 380Volts. We are little confused! Also, old Standee cannot be repaired, can we replace with Wire -Wound or Ceramic 5watt resistor. Sachin D [/QUOTE]
