[Elecraft] xv50

Joe,

Great that you now have the XV144 now stable.

It would appear that the power module has gone "belly up".  I don't know 
if Elecraft has any left (the XV50 was discontinued), but you can check. 
  Also check at RF Parts to see if you can find one.
As I recall, that power module was discontinued.

This kit was partially put together by my father in law who purchased it before he passed. Then about ten years later I decided to finish it. But any how when I went to replace Q5 it looked like two of the legs may have been solder bridged and shorted. Maybe it as not bad. But I was already unsoldering it and had a new one so I just went ahead and replaced it. Then it would turn on after that. Then in the alignment I was not getting voltage at TP5 with the radio keyed. Re soldered some joint I found that looked suspect and once again cleaned all the flux from the board. I had voltage at TP5 for a short time. Then it went away upon investigating I realized I did not have that coax selected at the coax switch to go to the dummy. So I guess I transmitted into an open ended coax. Probably SWR way to high. And I probably burned up the power module. Looking fr
>   om the front of the Xverter on the third lead toward the rear I have 13 VDC. On the second one back I get 4.4 VDC when keying. But never get any worth while at the fourth one back. All I get there is about .011  when keyed. So IT looks like the power module is getting power and is being keyed but I am not getting anything out of it. Just hoping for someone to tell me if this is correct and maybe if I can get this part from Elecraft or not.
