Have you checked the lopty for shorts . I have a lopty tester if any help you could borrow.<br>
<br>
I also may have the capacitor you are looking for.<br>
<br>
The transistor, I have diodes and BU407's which you could use to test before buying an original. <br>

Hi all,<br>
<br>
I am looking to track down a *BU407D *NPN Power Transistor for my<br>
VT101 terminal.<br>
They are commonly available online, but I was hoping to find one locally to save the shipping time.<br>
<br>
I also need to order a replacement capacitor, so if anyone is doing a DigiKey order any time soon I would appreciate it if I could add an item to that order.<br>
<br>
Thank You,<br>
Ashlin<br>
