Identifying components on color classic analog board

[Jimbo Slice]

I recently got my color classic back into proper working order but I'd still like to replace these burned out components to prevent any future issues. I'm having trouble confirming replacement components for DL21, DL22 and R11. A website detailing the VGA mod replaces DL21/22 with 18V Zener diodes (Part no. BZX85C18) but I'm not sure if that will work with my unmodded color classic. The resistor should be simple enough to replace but one end is burned so I can't read it and i'n not sure testing its resistance in this state would be reliable. Any help would be greatly appreciated, thanks!

I'll take mine apart and take a look for ya.

Ok so the resistor replacement can be found here (375ohms) and the two diodes should work just fine.

awesome, thank you!!

No problem!

Any other source for those resistors? Unfortunately, it appears only bulk orders of 100, at $10 each would mean I'd spend $990 dollars to have 99 spares. I'm just looking for a like-for-like replacement, and mine is similarly burnt up.

Think this will work.

So 400mW won't be a problem, there?

I don’t imagine it’s an issue it’s not a super high strain on the part.
