1. [Amps] Blown anode choke in TL-922 (score: 1): Author: "Alf Pousar" <alf.pousar@surffi.net>; Date: Sun, 24 Apr 2011 11:45:26 +0300; Hi Isaac, I guess it's due to the fact you are running RTTY. The power dissipation is a totally different ball game for RTTY vs SSB. Your working is similar to keydown for the entire qso during trans; /archives//html/Amps/2011-04/msg00499.html (7,044 bytes)

That means that he had 'an event'. The browning of the wires of the plate choke is not consistent with the symptoms (bang) that Isaac des; /archives//html/Amps/2011-04/msg00500.html (8,511 bytes)

A home brew choke without checking resonances would be my guess. It takes very little deviation to shift that resonance which is almost always between 25-28; /archives//html/Amps/2011-04/msg00501.html (10,629 bytes)

A bang at 3kV always makes for a memorable event. He'll be standing back and using a long broom handle to throw that switch for the next few times, I bet.

At his stage no other damage is seen or measured. BTW IMHO, RTTY - as I work; /archives//html/Amps/2011-04/msg00504.html (8,365 bytes)

Makes sense. But how do you account for the fact that it po; /archives//html/Amps/2011-04/msg00506.html (7,841 bytes)
