Brand: Ameritron

People of Ameritron are not keen in flawless drawing understandable diagrams. They are even inconsistent when drafting the components. Of the same device circulates different schematics! To more understand the track of the meters I drew the schematic differently. Now one can see how a rcing in the tube blows the 50 Ohm resistor and partly.

simple to install,works great

The hardest part of installing this was taking all the cover screws off my amp. No soldering--it just screws into place with 4 screws onto the ALS-600. They include an install sheet with pictures. Took me 10 minutes and now the amp does 12m and 10m, and the cost was extremely reasonable. Just check your serial number to make sure you get the right model of board; there is one for older amps and one for newer ones.

The Ameritron AL-811 10 meter mod is simple to do if you have just a little mechanical ability.

Now that the FCC have rolled back or removed the ten meter ban on amplifiers. Companies are selling them so it should be safe to share this.

Ameritron AL-811 10 Meter Mod

Modifying this amplifier for 10/12 meters, this use to require sending a copy of your license to Ameritron. Use this link Ameritron requests. Then they would send you directions. I recommend you do that now, especially if it is a new amp. If you have not bought it yet you may want to ask if they can do it for you. Their directions will not ruin the warranty.

1. Take off the window on the bake panel and see if you can see the green wire. If not then take out the cover screws and remove the top. Locate the rear panel PC board and the AUX tuning coil from the rear panel.
2. Looking down along the rear you should see the green wire connected from the PC board to the AUX tuned input coil as shown in the diagram. Cut the green wire and make sure it will not touch or go to ground.
3. Replace the window or cover and screws.

In some cases a high SWR may occur at the amplifier input. You will have to adjust the AUX tuned-input circuit slug with a plastic 0.1” hex T.V. tuning tool.

Put the tuning tool in place, tune the amplifier and tune for the lowest SWR while transmitting. Ameritron amps usually come pre-set for 10m (AUX tuning).

You may use 12 meters more than 10 and want to tune it for better performance. Re-tune the slug for lowest SWR in the middle of the 12 meter band. Or you could compromise the match, setting it for halfway between the 10m dip and the 12m dip. This will make it work on on both bands.

Watch the grid drive while doing this with the 811A tubes. They do not like to be over driven over driven.
