Dieter Horst <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Hi Vic and group,
some years ago I replaced a 'semi-faulty' transistor in the audio chain which caused some kind of noise or rumble. Unfortunately, I don't remember which transistor it was. It most likely was located on the 2nd IF / Audio board. In general, try to find out whether your noise is caused by the audio amp or some other source. What happens if you disconnect the antenna? BTW, the hum from the switch line for the PS7 mentioned by other list members, I encountered here as well. 73, Dieter DL5RDO > [EMAIL PROTECTED] made an utterence to the drakelist gang > ---------------------------------------------------------------------- > Greetings. > I recently put a TR-7 on the air that I purchased several months ago.
