    I am trying to connect 220 volt inside the amp, and find the manual not much help. Would some one know the proper terminals to connect for 220 volt use. I also notice some terminals are doubled up also.

    Thanks much.

    The manual is great help, as it clearly shows exactly what to do on Page 4 of the manual.

    But the connections are clearly shown -- what's not helpful about the diagram?

    Carol Maher, W4CLM at FoxTango (Yaesu International User's Group) has the photos --
    what do you need to understand ?

    Have you measured the actual voltage at your 240 VAC outlet ??
    In the USA, this voltage can be that high -- or higher.

    Properly Wiring your FL-2011B for 220/240 VAC ... it shows both USA (234 VAC) and Europe (220 VAC)
    READ and SELECT USA wiring !! ... 234 VAC -- the 117 VAC windings are wired in series.

    You WILL end up with an extra jumper when you go from 120 to 240 VAC.
    What are you using for a PLUG and RECEPTACLE ?

    Did you get your Yaesu FL-2011b transformer (AC) primary wiring changed and operating on 240 VAC correctly ?

    Give WIK some slack. He's been doing it so long his memories of being inexperienced are slowly being erased because of the new stuff fed in. Being a smartass is just his way of slowing the loss of data. :)
