How to Build an 11 - 10 meter liner amplifier. 4 pill

This is a video side show of how to build a liner amplifier for use on 10 and 11 meters. These plans show how to build an amplifier very similar to Davemade, Fatboy and Xforce.

You can follow the slides and build one of these amps. The amplifer in the design is a 4 pill amplifier, but using this basic design you can build any number of pills amplifier.

You can purchase parts from the following websites.

This is from a collection of amplifier plans released by PFS technology and originally called power plate amplifiers. Rick Wilson was the owner and designer of these plans. This was during the late 90's. At some point after that someone had taken a copy of these plans and stripped out whatever PFS logo's they could from the PDF's and photos. Any manuals or photoframes they could not remove these logos, they simply discarded. They then took these stripped down amp plans and started selling them on their own. These plans are still around the Internet in various places. They are missing a lot of plans, and stop at a class c 16 pill amplifier. As well after the 1x4 design, you will be laking the full manual and any further explanations as well as limited photoframes. I have posted the following slide show for EDUCATIONAL purposes. I will be posting information from the “AMPPLANS” that have continued to circulate the Internet. I will not however post any from the full plans since they have not been linked in order to protect Rick Wilson's intellectual property. They only reason I will post these is because they have been widely distributed.
