Dennis, Remove anode connector from tube, run test again. This will help localize where the problem is. If it is before the tube you will still blow the glitch resistor. Art KB7WW
Dan, Why not try to find an AM-6155 or AM-6154, They are complete with power supply and a fairly small package. Do a web search for them and see what is involved in converting them. You can start her
I don't mind people or companies letting us know when they have something to sell that is of general interest of the list. What bothers is those who do NOT include the price. They must have a price w
Anyone have a spec sheet for an 8877. Can't seem to find anything on the but the short form. What I need is the cooling air requirements for both 1500 and 1000 watt dissipation. If you know where the
Bob, Do a search with your favorite search engine on the GI7B and follow the results and see what our brethren in europe are using to cool these tubes. Most are using Muffin fans to cool 2 of them. A
Bill, It's been a while but if I recall correctly all that is needed is to change to low profile plate caps. the 500 are slightly taller than the 400. Also when SWAN went to the 3-500 in the Mark 2 a
