25 Sep 2006 I am trying to tune my AL-811 amp properly (into resonant antenna), and I read the following from the W8JI site (and the instructions for my amp):
AL 80A How to tune an amp. plate current to make sure they are within limits. In lieu of this read W8JI site for the correct way to tune an amp. There have been several posts cautioning people who follow K4RVN's simple amp tuning instructions to make sure grid current is within specs. In all fairness to
For example, I have an amplifier bias control, transmit-receive relay sequencing, and metering board that works with amplifiers up to 10 amps plate current. That board accepts TOF modules . Please review the instructions below and be sure you are completely comfortable with installation. The base TOF1 for the AL-811
5 Oct 2011 Occasionally, first-time amplifier owners have difficulty understanding manual tuning instructions. Reading all manual tuning steps and “dry practicing" (without actually transmitting) all manual tuning steps will make initial operation much easier and safer. We wish amplifier-tuning instructions could be

1 Jan 2012 Grounded Grid Amplifier Neutralization. While there may be exceptions, neutralization of a high frequency PA (power amplifier) vacuum tube amplifier has little to do with VHF or UHF stability. VHF instability is almost always caused by a high impedance (or even parallel resonant) path from grid-to-ground.
29 Mar 1997 From: w8jitom@worldnet.att.net (Tom Rauch (W8JI)) Here it is: > > The amplifier should be tuned up for the maximum output that you > intend to use at that time. Following the tune up instructions will result in a clean SSB signal, because, JUST like you suggested, the amplifier will be overcoupled.
Some amplifiers drive too easy to do this, so we should always pay attention to factory instructions and avoid exceeding factory amplifier tuning current limits, especially for control and screen grids. Grid current is especially important to watch because grids often do not have sufficient thermal mass to absorb large overloads
Modifications and service of AL811 amplifier Ameritron.
An amplifier with the input applied between the cathode and grid and the output between the anode and grid is called a grounded-grid amplifier. This is true . This works in the same direction as control grid to cathode voltage, also tending to increase or decrease anode current in step with the effects on the control grid.
