If u scroll through the messages... u will see that # 863 has been blown out ! I responded to it last night... then it comes back as "message 863 can't be retrieved" Did the fellow blow it out

3, YC--156s mobile. Roger that good buddy. I drive a car that uses a 208v battery. R L Measures, AG6K, 805.386.3734 r@..., , rlm@..., www.somis.org

Not a sound wager, The 100Ω MOF resistors we use in our suppressor retrofit kits are 20mm long and they have c. 11nH of inductance. You would do well to read Fred Terman's chapter on inductance. >

So why didn't they fail?

With the 4cx3000A, most of the noise comes from the exhaust side of the variegated anode cooling fins. The sound made is similar to wind blowing through pine trees. R L Measures, AG6K, 805.386.3734

From TV sweep tubes? Not likely. . This is roughly what I've measured on the air.

My shack is not much larger than yours, Jim. My Harris RF-110A is sitting in the bathroom. There is a large cooling fan in the ceiling to pull the hot air into the attic. The Harris is no-tune, 1.8-30
