Alistair, It is the code 127. I’m still unsure from your answer if I should replace the rectifier with an updated one, or stop worrying about it. Because the difference is pennies, I think I’ll stick to the higher tolerance caps.
Does it make sense not to order anything until the tester arrives in order to determine the wattage of the resistors? Higher wattage, bigger physical size? I have studied the color coding for the resistors, but wattage wasn’t mentioned on the chart and doesn’t seem to be indicated by the stripes. I will trace all the circuits on the schematic one by one and try to understand what I’m looking at. The learning curve is steep when you’re starting from scratch.
