    The low voltage sample of the anode voltage doesn't make the monitor work or work better. It's just for protection. You could unplug it...

    The divider is for x-ray protection (from 26KV or so it gets a 10-20V sample) and can be bypassed (and tossed) so the anode voltage is...

    CR-70 or CR-71 B&K adapters are rare and probably expensive. Get yourself a socket and make your own adapter.

    Not a knot but same thing on a Sony TV. Long lead allows to pull the chassis out and put it on its side for servicing while keeping it...

    M K L replied to the thread Width coil.
    Non-adjustable coils are absolutely normal if you have a size trimmer. If that's not enough there might be a narrow/wide jumper that...

    You don't. There should be a trimmer for that (H size).

    The monitor is surely a Nanao MS-2931 so a cap kit for that model should be correct.

    No, it's either 1 or 4. So 1-3 (stock) or 4-3 (for which you need to cut the trace to 1).

    A is the HOT collector (if the "jumper" in the above pic is set) . If you use pin 1 of the flyback for the HOT collector (as on a stock...

    If you can measure inductance (LCR meter), measure (better if with flyback off circuit) across pin 1 and 3. The original flyback (Eldor...

    M K L replied to the thread Neotec 2515C Good B+ no image.
    Measuring resistance across pins is pointless. The only relevant info is that the primary winding (1-2) is isolated from the secondary...

    If it's just loose and not cracked the flyback will work anyway. Worst case it will make some buzzing noise that you can fix with some...

    M K L replied to the thread Neotec 2515C Good B+ no image.
    This kind of HOT with built-in damper diode also has a low ohm resistor (40-50 ohm) across base and emitter. It's low enough to make the...

    M K L replied to the thread Horizontal collapse k7400 *solved*.
    It does or you wouldn't have a picture, albeit collapsed, without flyback operation/high voltage. Check continuity from the pin of the...

    You need to lift one side of this resistor, attach bulb and meter to it and adjust the voltage to 145V (B+ for the European Polo is...
