    Standalone EK10

    Hello,

    I have the following components:

    EK10
    AR for EK10
    VDE10
    U10/E
    UF10/E

    I assume I can build a standalone setup for the EK10 from these components, but all cabling schemes I have seen include at least the SchK13, as additional component.

    The 28v BB+/BB- is obvious. AE is for anode. E for Erd ? .
    Antenna ? Should I use a 50 or 60 ohm cable ? Any wire antenna will fit ?
    MBB ? That is 12v for RV12 tubes. Is that provided externally ? From which component ?

    I know those are basic questions, but RTFM does not provide all answers

    Thanks for any hint

    Half the valves are powered from -BB to MBB, the other half from MBB to +BB, so MBB will automatically end up roughly in the middle of the supply voltage. You could probably operate the receiver safely using 24-27 Volts, the two groups of valves will be in series and if a valve goes in one group it should not upset the balance too much but there is a small possibility that the failure of one valve can lead to an over voltage on the other valves which leads to a cascade effect of burned out valves. This is why they originally used a resistor bridge to control the MBB voltage. Normally these resistors are situated in the mounting frame of the RG10. You could also use a WK25 for this purpose.

    E is indeed Erde. You can use almost anything as an antenna. In the aircraft the antenna was tuned via the AAG's, but for reception only you don't need bother with a tuned antenna.

    Have fun!

      Thanks FS

      I have a extra WK25 I can use for the MBB.

      Some fun for my next holiday

        Ah, and I forgot to ask, do you have the resistor box fitted to your UF10E?

        regards,

              Hello FS,

              One more question: AE- is not mentioned on the EK10 schema. Should I connect AE- from U10 to Epf pin ? Seems logical, but ....

              Setup is at last done. Will start powering up.

              Cheers

                E10K Connection

                I have made an internet site about using the E10K
                Look here:
