Just the fix!After quite a few years of regular use, the transformer on my B60 blaster quit working. Not only did this correct the bad transformer, I got a new switch with a clear cover, so I could now see the switch.
This fixed the problem with the transformer, but apparently the same event that ruined the old transformer also damaged the fluorescent light bar in the cabinet, so I took the opportunity to "upgrade" to the LED retrofit.
