ON PIN 5 I HAVE -67V ON PIN 3 I HAVE 252. WHAT IS THE VOLTAGE SURPOSED TO BE ON PIN 3&5? THE 6146 LOOKS LIKE IT HAS A SLIGHT BLUE TINT TO IT IN THE DARK.THIS BOX HAS A CR4&CR3 BOARD THAT ALL THE LETTERS AND NUMBERS FOR PARTS MATCH WITH THE 5-B SCHEMATICS & NOT THE 8-A BUT THE VALUES ARE THE SAME ON THOES TWO BOARDS. R28 IS A LONG WIREWOUND POWER RESISTOR THAT LEADS TO THE ORANGE WIRE THAT GOES TO PIN 3.I ORDERED NEW OA2 TUBES&6146"S THE OTHER OA2 TUBES CKED OK BUT I COULD HAVE A BAD TUBE TESTER. I HAVE-35V ON THE YELLOW WIRES FROM THE TRANSFORMER ON THE CR4 BOARD ON BOTH SIDES OF R35 I HAVE-68V & ON BOTH SIDES OF L12 I HAVE-67V ANY HELP WOULD BE GREATLY APPERICATED. |
