我台现用的10kw中波机是70年代生产的屏调机，体积大，效率低、指标差，为此我台将该机的限放、低前和高前电子管电路改造为固态化电路，现介绍如下：1．技术改造说明1．l用固态化电路代替原机低前各级电子管电路（图1）。（用音频处理器代替限放）。该电路分为低前和低末前功?
I Taiwan is currently using the 10kw wave machine is the production of 70s screen machine, bulky, low efficiency, poor indicators, for which I Taiwan will limit the machine, low and high before the tube circuit into a solid-state circuit Now introduced as follows: 1. Technical transformation instructions l solid state circuit instead of the original low-level before the tube circuit (Figure 1). (Audio processor instead of limit). The circuit is divided into low before and after the end of power?
