OK... I don't recall, but if he no longer needs it, PM me. Please? 73, ron w3wn I took mine out so the supply runs cooler - the speaker is perfect and includes that bracket. Who made the original req
About: "The linear supplies are not very efficient, and use a lot of power just idling, (etc.)" Linear supplies not having current drawn (no load) should not dissipate any power at all. 73, Roy K6XK
"Not true. A power transformer connected to the power line will draw magnetizing current, and there will be power dissipated." In spirit if the original statement, of course I assumed the peripheral,
Not to be a killjoy but: Personally I would be careful in the wholesale replacement of electrolytics with Tantalum caps. Tantalum caps can not stand the inrush current that electrolytics can which ca
"They require some series impedance from the voltage source to the cap so as not to exceed the inrush current." Of course adding a series resistance completely destroys the benefit of a low ESR, defe
Don't dismay...there's a way. A 52-ohm dummy load with a rectifier and filter cap yields an accurate dc voltage in proportion to the power being dissipated. Today's vom's and dvm's are pretty accurat

"Questions - 1) What if I put those ferrite beads on ALL my coax jumper cables as they run between rig and amp and tuner ? Any downside to this ? 3) What if I do both 1) and 2)... and install them al

"The only fan noise in my shack comes from my TenTec Centurion amplifier that I sometimes run." A remote-located blower is the solution. A flexible clothes dryer hose works perfectly, with a squirrel
"...and liked Ten-Tec's QSK rigs a lot. As a keen CW operator I do hate the new slogan" I like to think we are allowing the silly sideblasters to pay for most of the development and mass-production o
I quoted that statement -- didn't make it. See below. 73, Roy K6XK Roy, do you hate the new slogan so badly that you would not buy another Ten-Tec? (me neither). From a business point of view, CW is
FWIW - I just put LEDs in a T2X controller internally lit meter - with diffused LEDS - don't like it very well.Played a lot with current and sanding them more etc. OK, I got radical. I fashioned a st
