![]() ![]() A compact and Macintosh and Firmware and too often. Anyone got a copy they could send? I hate to throw it out, it was working so well for curve tracer duty.Geforce 179.28. But I can't find my CD with version 2 from 1997. They have an update to version 3 if you have version 2. PICTUREWORKS LIVE Multimedia Application Software captures high quality pictures and still video, controls the camera features, edits and enhances pictures and more." "The DVC323 comes with KODAK DIGITAL SCIENCE Picture Easy Software. But not the included application software: Was able to get the driver for the camera. With rememberances of past and honorable service and best wishes for the next life. We dutifully lay this GU-50 to rest on this sad day. "One question, How you feel now after describing the dead body of this tube? Did you learnt any? I am feeling happy with your description but the circus need images." (note: the grids were a bit straighter before I mangled them to get the mica off the bottom end) Pictures! I used my Fuji camera instead and reduced the size. Interior plate is a shiny metal surface, other than the big black spot where Jerry smoked it! (or was that just normal operation and the tube got drop tested?) (the tube pins are not magnetic however) Plate has some kind of gray coating/surface. 0.9 mm glass thichness.Īll interior metal is magnetic, so I assume it is Nickel. ![]() Glass envelope is 40 mm external diameter. g2 has a heat dissipator radiator box at the top end. The long slots along the outer edges of the plate assembly are most likely for performing/observing the grid alignment during assembly. No internal Barkhausen fins on the plate assembly. Plate is 21 mm width external along grid supports axis, and 30 mm wide across its own support axis fins. Internal plate is 11 mm spacing from side to side above cathode areas. Plate is 35 mm long at center and 38 mm long at supports. (g3 has a 8 mm to 15 mm external aspect, g2 has a 5 mm to 9 mm aspect, g1 has a 3 to 5.5 mm aspect) Looks like about 0.66 mm spacing between the cathode surface and g1 wires.Ĭathode is 32 mm length for the active coated area. (elliptical shape cross section with truncated flat edges near the g1 support rods) The grids are also elliptical shape cross section. The cathode appears to be 3 mm wide by 1.5 to 2 mm thick. All the grids have a thin metal band elliptically wrapped around the grid ends (not flat like a frame grid), apparently for alignment during assembly, and the grid 1 bands also shield the uncoated portions of the cathode and are within the confines of the g2 wires. The grid 3 has 24 wire wrappings and is not wire aligned or matched with the inner grids. The winding pitch for g1 and g2 is matched and the wires appear to be well aligned. Grid 1 has 35 wire wrappings along its length, and grid 2 has 36 wire wrappings along its length. This is (or was) a Ulyanov GU-50, ry-50, tube with the triple converging curves logo and an OTH 57 marking inside of a diamond shape. There had been some conflicting posts on GU-50 alignment in the past. I was curious as to whether the g1 and g2 grid assemblies were aligned wire-wise for low screen current. I just dissected the internals of a previously destructive tested Russian GU-50 pentode, kindly sent over by jerrys. ![]()
