These pages are my personal notes (mainly photographic records at this stage) on modifying and implementing various circuit improvements to enhance the operational performance and reliability of a Kenwood TL-922 amateur bands H.F. Linear Amplifier. Most of the ideas came from researching the web on how to improve this fine old amplifier. Some mods are more worthwhile implementing than others. After working on quite a few of these amps over a period, I've settled on the modifications depicted in the following pages as some of the most desirable, these being Q.S.K. for SSB operation, step/start A.C. mains supply and improved VHF parasitic suppression. There are a number of ways to achieve these outcomes. If you have questions please send me an e-mail and I'll do my best to assist. Last updated on Saturday, 03 May 2008
