John, Asside from the physical size of the innards, I always thought the 3-400z had the same base as the 3-500z? If so, about the only thing will change is the increased pate current if you run them
If you have an electrical supply, Lowes, or Home Depot around, they have everything from the new cord to the recepticle. You need a Range cord and recepticle or one for say a 30 amp 220 volt line. Th
I forgot to ad this, If you have a cord with a plastic cord grip, I always take this out. I then open up the hole for a romex clamp like fits in a 1/2" conduit hole in a box. These take a 7/8" hole i
John, I didn't think it would be much of a change but is the sockets different between the two, I always thought they were the same? That's what has me thrown, why would you need to change the socket
Scott, They custom make some air variables with a low min C by the way the rotor plates are designed but those are expensive. The reason you need low C is first the tube has so much capacitance. Next
George, Your correct. The tubes though that do intermittantly spit or arc I've noticed folks are running them right at the maximum or over the maximum rated plate voltage. Tubes aren't evacuated 100%
Mike, That was one of the reasons I used them plus they were cheaper than going and buying a piece of SO cord and a plug. They make some smaller for large window air conditioners running on 220 Vac t
Colin, That's true as long as the cable is rated for 220 Vac, and you don't want to add a ground with the neutral. To do it right, I'd want a three wire with ground cord. Most 120 Vac cords only have
Most manufacturers, size the transformer to what the amp does. It's according to what the amp is made for SSB only or AM/SSB. If for SSB only, you'll find the transformer to be maybe 25% smaller than
Bill, I can tell you that the NEC sure does frown on using white as a hot. There's only one permissible way they allow it and that is for the switch leg on a wall controlling an overhead lamp. There

I have no problem about the current rating as I know it's 1/2 at 120 Vac. I just dont like to run a white wire as a hot wire or especially a ground. I do remember though about re-coloring the wire as
Ian, Your correct about the differences! I've seen the innards of several types of transmitting tubes though and never seen a true getter like the ones used in receiving tubes. Where are they in them
John, Well no! About every amp now is made for AM/SSB use unless it says it's for SSB only (some do), it says it in the manuals or on their advertizements. Some has you to change the plate voltage ta
Ian, Thanks as I didn't understand what you meant. I take it when this coating is heated, it traps the gas molocules by the reaction. Receiving tube getters absorbs the gas during the flash from a ch
Jim, Tubes sure have a shelf life or I always thought they did. The seals to keep air out of the vacuum, I think, can leak even though a very miunute amount. Over time though, this keeps building. Th
Jim, I should have added that those arcs, even though one might think minor, put's a quick surge to any power supply of several amps current similar to taking the B+ lead and quickly shorting it to g
John, Yup, I know a guy doing it. The main big one in Fl goes by Ghost Rider if I recall but don't know his real name. I found out about him from a transformer company in New Jersy who makes transfor
Bill, Your correct. That's a similar thing to what is done in cleaning or rejuvenating a CRT. The arc burns this stuff off and restores it's function. I've saved a many a CRT using a rejuvenator. Any
See below, ** REPLY SEPARATOR ** In B/W and color CRTs this actually does happen but to be honest, it's been so long I forget the process that causes it. If I can run across my books on it, I'll look
