The L-4B fan is "silent". It has oiler tubes, and Drake recommended oiling with a couple of drops once a year. (Maybe twice?)

"Tom Taylor \(MSTV\)" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Drake Aficionados, I'm putting a recently purchased L-4B back on the air after the amp has experienced an unknown period of inactivity. When I powered up the L-4B last night for the first time, I noticed a rather loud hum coming from the L-4B amp deck. I reached around the back of the unit and stopped the squirrel cage fan with my fingers and the noise stopped. From reading reviews, the L-4B has earned a reputation as being relatively quiet. Has anyone else experienced a loud hum from their L-4B fan? Have you cured it? Can the L-4B's fan motor be lubricated? Curious, Tom N7TM p.s. I made the unobtanium VOX/relay plugs for the amp and ac4 using a suggestion on Garey Barrell's web site. I used 3/16" brass tube for the pins, small rectangles of plexiglass with drilled holes to hold the pins, and epoxy to seal the wires and the back ends of the plugs.
