Subject: Ungar 9900 Soldering Iron Base Station

Complaint: Dead

Diagnosis: Secondary on power transformer is open

Reason: Shit tier QA at factory didn't notice a wire strand bridged across the power transformer output.

Hard to believe they missed that, it's one of the strands from the power transformer's wire. I can't fix it as-is, it will need a replacement transformer or an external transformer. Can't use DC because this particular model uses a light dimmer-like circuit (Triac) to control the heater of the iron.

If I can find spares, that's great, but if it dies at some point then it dies.

I can imagine trying to find parts for this one will be like trying to find parts for my old Edsyn units. I bought every tip for my irons the manufacturer had left. When they're gone, they're gone.

When they're gone, they're gone.

Sad but true.
