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!
