This one already has some parts replaced but it will help you identify any remaining original parts. You will notice that the set used 'dog bone' resistors and I can only see one in your picture (100K with yellow dot). |
Thanks PJL, thats a helpful picture as the layout drawing on the 582 sheet is very dark and hard to see clearly. There are 2 more dog bones in my radio, a 400 ohm on V1 and a big 410 ohm (5W possibly) on V5 which is also there on the photo you found - I like the look of these - will test them and see how they measure. is there a way to determine the wattages of the dog bone resistors and therefore the replacements required if not on the schematic / circuit diagram other than finding a similar size?
