I have done considerabl repair on electronic circuits but mostly tube. Now I have a great bargain in a piece of HP Test Equipment that is partially working. The DVM Option to this counter an HP 5823a is not working. Opening the case and applying power there is smoke coming from one particular component. Looks like a small TO black plasti9c with a small mounting tab/heatsink TO-200 or 220? Anyway the markings are clear there are two of these similar components near to each other. The markings are as follows:
M (Motorola M symbol) 426 then below 4-514
M (Motorola M Symbol) 013 then below 4-514 (EBC markings on tab)
At first I thought this was a three temrinal regulator Know I'm not sure. The 426 is the one with the smoke and it apparently has already been replaced. Perhaps this is a complementary pair??
Can anyone identify these components?
