It is always fun to combine hobbies. I have fixed a couple old tube radios so I thought why not build some test equipment and use up some scrap wood in the process? The result is a shop made dim bulb tester and a test speaker. I had the speaker and grille in a box of parts so I figured I needed a way put it to use. I reallize that the dim bulb tester probably would not meet UL approval, but I figure since it is only used while being watched, I should be ok. Now all I need is another radio to fix!
