Quoted from jj44114:Replace with a beefier diode like 1n4006 or 1n4007.
The problem here is current not voltage so using higher voltage version diodes with the same current spec (1 amp) as the 1N4004 currently installed won't make any difference to them cooking.
These are 1.5 amps and physically bigger to dissipate heat a little better:

I'd probably install 2 amp diodes for more headroom.
If you're talking about the different looking parts at C17, C20, C21 and C24 between both boards they are actually all capacitors, just from different manufacturers.
Quoted from Zablon:Really? Huh...well I guess that makes sense since they are marked "C"....but i just assumed those things that looked like resistors were resistors. (I admit I didn't really check the schematic for the diagram of what they are).
You might notice that some Bally MPU boards have a lot of green color banded capacitors that look like resistors too. Easy assumption to make.
