If you are worried, then get an lm317 three terminal regulator and a
suitable pot and get it just right on a charger with more volts out, like one of those beefier usb ones. It might get a bit warm. Seems odd to me if its AC though, as leds are most definitely DC.

Also worth opening up the old transformer and see if just the thermal fuse has failed? |

, says... European audio equipment almost always used circular 5-pin 180 degree DIN connectors for mic and line level inputs, and line level outputs .... One 5-pin plug could handle both stereo inputs and outputs on a single connector so that tape recorder connected to a mixer, for example, could have line level outputs for playback and line level inputs for recording from a vatiety of sources with one cable although it was adviseable to use cable with four individually screened conductors to avoid crosstalk. A radio might be equipped with a so-called Diode connector in which the record and playback functions were reversed so that the same straight through cable without a crossover could be used to connect a tape recorder and receiver together. The original connecors with a solid metal barrel were excellent but the later ones with two plated half screens punched out of thin sheet metal with the whole thing held together by a plastic sleeve were not so good. They worked fine but were too suscepible to damage if one dangled on the floor and got trodden on! The original phono plugs which were around at the time, though, were terrible by comparison! -- Terry --- This email has been checked for viruses by AVG. http://www.avg.com |

But do have a smaller footprint on the rear panel. There are much higher quality connectors made to the same pin layout by Touchel. Which have locking rings too.

This implies an autotransformer with a single coil and that is *not* an isolating transformer. When are you taking it apart to see what's actually inside? complete nonsense So what do you think it means? |

However the conclusion that it means the transformer is unisolated is simply nonsense. NT |

However your assumption that it is is based on what it says even though it contradicts itself. That makes your assumption nonsense not mine. |
