| CC analog board DL21 & DL22 values? |
Posted by: mraroid on 2016-04-29 11:35:14
Can someone post the value (s) of the two zener diodes DL21 and DL22 on the Color Classic analog board?
I am placing a order with mouser and I would like to order some.

Did you find out what the values are? Also what do these diodes do? Both of mine are fried and I have no sound on mine...

I believe both values are the same and the part number is: BZX85C18
I like Mouser:

less the 50 cents each. Mouser has low cost, non rip off shipping.
Keep us updated.

all CCs out there those diodes get hot and cook the PCB. its a known thing, bad design, by the time the LC520 came around they did away with it in a newer design. They serve as a poor mans regulator for one of the scan B+ voltages.

jack Did you ever find anything? I'm looking to do the same but they aren't manufactured any longer, having trouble finding anything. |

Has anyone tried using a larger package like a DO-201 or mounting it higher to help with heat dissipation? |

I'm concerned about choosing a part with the wrong specs. I have another spot on my board that is slightly toasted where a smaller diode sits below some resistors. I would like to fix both of those. |
