Sorry HV stands for High Voltage. It also has an alias known as B+. Respect it it can be shocking. Like fire needing air water and fuel a radio needs certain properties to operate. HV is one of them. In the power supply section of you set that would be the power transformer, the 80 tube and the electrolytic caps. If it is working properly these parts will make about 220volt DC at either of the filament pins of the 80 tube and at the+side of the electrolytic caps to chassis ground. So what you do to measure this voltage is set your meter for DC VOLTS and the range up to 500v if your meter isn't one that has an autoragne feature. The black probe hooks to the chassis and the red probe touches one of the fat pins of the 80 tube. You should see on your meter a few hundred volt. Two important things when you replaced the electrolytic caps the + side must be connected towards + side of the HV line. No +'s connected to the chassis. And watch out for the angry 80 tube. The 80 should have it's filament lit when the set is on. Look at it and see if the part around the the filament is called the plate. It should stay nice and black if it starts to glow a faint red or you see sparks inside it turn the set off you've got a short that will burn out the power transformer. If this is going to happen it will occur in the first few seconds of turn the set on.
