Your anecdote missed two important facts: 1) The amplifier was stable with the top cover on ... you made a change, probably in the plate circuit stray capacitance when you moved the top cover. That

To be effective the filament rheostat would require built-in metering with proper RF decoupling at considerably more cost or would encourage semi-trained appliance operators to operate their amplifi

I'm not arguing that improper filament voltage doesn't shorten tube life or reduce RF output. Simply, given the design of most commercially available amateur amplifiers it would not be safe to inclu

It may be more simple than tuning a tank except that one does not need to open the cover to tune a tank. One must open the cover to measure filament voltage properly (directly at the filament pins).

Author: w8ik@arrl.net (Joe Subich, W8IK)
Date: Sun, 19 Mar 2000 19:16:55 -0500
Dick, "hot switching" simply means operating a switch (or relay) with voltage (DC, LF or RF) applied. In the case of the FT-990, the input relay (or input contact) of the amplifier will almost certa

Will, I am sorry you lacked the conviction to stay with your original decision. Like, I'm sure, a great number of readers of this reflector, I have learned to hit the "DELETE" key for many of Measure
