[Elecraft] Blown R58 relpaced, still no power out, does anyone have any hints?

[Stephen John Farthing]

Hi Guys,

A few weeks ago I managed to induce a fault into my K2 by transmitting 
into no load when testing the top band option. I found that R58, the 180 
ohm, half watt resitior at the far end of T4 had been damaged and had a 
value of 4 ohms. So I replaced it and reassembled the K2 and I still 
have no power out. Before I remove all of the options (ATU, Top Band and 
SB) and take it back to basics, which will take time will not have for a 
month or so, can anyone suggest other components I might 
check.....everything else seemed ok including the PA Transistors......

Also, what is the purpose of R58? Sorry guys but i am just not as clever 
as the rest of you, I do software for a living, not electronics...but I 
am learning..

Regards,
