2 Replacing Haunted House Lower Playfield Illumination Lamps with #44 Lamps
This modification documented by Chris Hibler, based on Black Hole mod developed by Steve Charland.
When Gottlieb® designed Black Hole and Haunted House, the designers chose to illuminate the lower playfield with 313 lamps, which are 28 volt lamps. Coil power could be used as a power source, and the lamps are slightly brighter than #44 lamps. However, #313 bulbs are triple the price of #44 lamps and are a unique part to stock.
Converting the power circuit that drives these lamps to 6VDC makes sense and allows the use of the more common #44 lamps.

All finished with the mod. The bulbs now will light on 6VDC instead of 24VDC. Swap out all of those #313s with #44s or #47s and never worry about looking for the correct bulb again.
3 Kicking target switch arcing capacitor
The main playfield circuit diagram shows a 3.3uF capacitor across the coil for each of the four kicking targets and rubber. However, on at least one machine, these were missing. The positive terminal of the capacitor goes to the cathode of the diode on the coil contacts. The photograph shows the left side targets with the capacitors added, plus the holders for the 3A slo-blo fuses recommended in one of Clay's Guides.
