This is a drive corrector that was sold to me with an orange tube Celestron C8, labeled Sidereal Electronics. It has the inverter to drive from 12 VDC and also the oscillator to run from 120 VAC. After first use, an output transistor blew. After transistor and other part replacements, it works but does not get the proper output voltage (only about 40VAC).
Does anyone have more information on the box's circuit? A schematic or possible fixes would be most helpful.
PS I changed the output resistors to a lower value, and I now get the proper output voltage but I want to be sure this won't harm the other components.
Seems to work fine now.
