1. [Amps] 6146B vs 6146W (score: 1)
Author: "Steven Cook" <sccook1@cox.net>

I have been reading up on the 6146 and would like to know if the "W" version would be suitable for use in a TS-830S. I have read that the "W" version is rated for less plate dissipation -- is this be

Thanks to all for the info on my 6146A/B/W question. Anyone out there know where to get the Kenwood YK-88C and YG-455C 500Hz filters for the TS-830S? I don't think they are available from Kenwood any

Well, Apparently the HAARP boys don't know how to put the "fire to the wire..." If they knew what they were doing, they'd put up a Buttered Cat Array. See if you follow this... SOME SCIENCE Fact #1.

Mega - Ditto's... Tubes are still the way to go unless you need your amp on battery power. At ~ $50 each, the 4CX800 is hard to beat. For the money, they are a better deal than the 3-500Z, even in it

Wondering if anyone knows what the Kenwood fan is rated at. It is awful quiet. I think its a 5"x5"x1.5" type muffin. 1700 RPM (too quiet to be 3300) Moves about 50 CFM perhaps This is my best guess.

Seems like the delay would only need to be long enough to limit the inrush current to the safe level specified for the tube filament and power supply diodes. In most cases I've encounter, 1/2 to 1 se

So if you are running AB2 at circa 3,000 volts on the plate, and let's say... 5 volts of zener bias, and 230 ma of grid current -- would be a little over 1 watt of grid dissipation. (.230 X 5 = 1.15
