    Hello to all you Hallicrafters enthusiasts..

    I'm looking for a source / any info, for the high voltage connectors seen on top of the P-26 power supply and on the back of the HA-2/HA-6 transverters. Actually now that I'm thinking about it I also need the black plug in connectors that resemble a tube socket. What I have are both transverters and a pristine almost new in the box P-26 supply but no cables.

    I've read here on another thread (http://forums.qrz.com/index.php?threads/hallicrafters-p-26-power-supply.245266/) that the high voltage cable is made by Johnson. Google makes me believe it's just the brand of cable/wire and not the actual connector. If anyone has source or can point me to a place to find these connectors please do. I could rig something up but that's really not what I want to do unless I'm forced to.

    Thanks!

    sounds like one of them is an 8 pin octal socket. possibly an 11 pin version.
    These were common on older equip. for multiple line control connections.
    You can make one from and old octal tube. just bust out the glass etc and hear the pin and shake out the solder.
    Or check RADIODAZE. the have a lot of stuff to rebuild old radios.
    tubes connectors, terminal strips, grillcloth etc.

    That's one way to do it ;) I should be able to handle the octal plugs. As for the other HV connector let me see if I can put up a picture here from that thread I mentioned above. Hope he doesn't mind..

    The two red HV connectors are what I'm looking for. Maybe that will help anyone wondering what I'm looking for.

    The 11-pin Black circular connectors (used with tube/relay) are Amphenol/WPI 78/86-series, also used on the Heathkit HP-23 and Collins S-Line 516F-2 power supplies.

    There's actually a correct name for the 11 pin connectors that are popular on hollow-state ham gear.

    The term is "magnal".

    I am not making this up.

    Eric,
    I may have some of what you need. I know there is a P-26 supply in the shop. Remember seeing the cable to the transverters. Should be a 5894 tube also. You know all to well the supply is a heavy dude. Any interest in any of it?

    SWR:

    You need to replace all of the electrolytic capacitors in the P-26 unless that has already been done. The capacitors visible in the photographs definitely look original and, if so, they are a time bomb waiting to go off and then cause all sorts of damage to the power supply.

    I do have a P-26 that I use with my HA-2 and HA-6 transverters. In addition, I have a home brew equivalent that I use with my HA-2 that was converted to 222 MHz.

    The Hallicrafters transverters are excellent and they can be driven with exciters that put out as much as 100-watts.
