Kevin LaHaie <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Hello Group
A good friend had his L4B experience a tube short, and she went with a BANG! 1 tube went, but he replaced both tubes, and brought the amp back up. It is putting out power, but he is experiencing a burning smell from the power supply and there is a noticable distortion on his transmitted signal. I convinced him to stop using the amp, and to open up the power supply (urging he use extra caution to bleed EACH capacitor in case a bleeder had failed)
He has performed a careful exam of the power supply internally, and he could see no evidence of a charred or burned component.
In looking at the schematic, there aren't too many candidates that would fail and still allow the supply to still function to a degree. Diodes, capacitors, resistors, and not many at that! (Of course, there is the transformer - yikes!)
I am sure someone has had a similar experience with the L4B supply, anyone care to share it and what you found?
Thanks and 73 Kevin K7ZS ---------------------------------------------------------------------- Submissions: [EMAIL PROTECTED] Unsubscribe: [EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost: [EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net ----------------------------------------------------------------------
