Bridge Rectifier
The bridge rectifier is an S15VB10 (100V 15A) chassis‐mount bridge rectifier with push‐on terminals (see Figure 8). Look
for a substitute with a continuous current rating of 15A or more and a PIV rating of at least 100V. Suitable substitutes
are the NTE5322, KBPC1501, or KBPC1502. Be sure to install the replacement with thermal paste filling the interface
between the part and the chassis, to facilitate heat flow. The NTE5322 is available from Allied Electronics and from
Amazon.

Lamp Intensity Control
The lamp intensity control is a 500Ω sliding potentiometer, with linear taper, and was manufactured by Noble (see
Figure 9). It has 60mm of travel, and the mounting holes are spaced 65mm on center. Before replacing this part, try
cleaning it with volume control/contact cleaner (with power removed from the equipment). Look for a substitute with a
power rating of at least 1/2W.
