Lately I have been restoring a Crosley 716 -744, the 716 chassis in the cube cabinet with the speaker on top. http://www.nostalgiaair.org/pagesbymodel...003598.pdf  The cabinet is very rough, so I am going to fabricate a brand new cabinet as a child sized console floor model. I have the whole chassis done, all the electrolytic and paper condensers replaced, and most of the resistors replaced too. Today I got the last resistors I needed in the mail, a 10 watt 10K and a 10 watt 15K to replace the two sections of the candohm, which was completely bad. When I went to install the tubes, I got to the last one, a 6N6, the audio output tube, and realized that the only tube I had left was a 6L6, which some fool must have put in instead of the 6N6 thinking, since it was an audio output tube they must be very similar, which, as soon as I looked at the schematic I realized they are NOT. The 6N6 is an odd type of double triode, where one section drives the other. The 6L6 is a power pentode. This is the first time I have run into the 6N6 used. Looking at the schematic it is clear the substitution would never work. Just to be sure nobody had played around with the circuitry to try to allow the substitution, I rang out and traced everything connected to that socket. It is, indeed, still correct for the 6N6. An old saying of my mother's ran through my head when I realized this situation, "The things you see when you don't have a gun!"
