[Heathkit] SB-200 Help

[KBØNLY]

Ok, i got my SB-200 hooked up and now i got more problems than i know what to do with.

Lets start from the top..

I built and installed a SK-201 Soft Key module and that works great, keys the relay no problem.

I followed the manual and hooked it all up.

And i went to the operating instructions, this is where everything went FUBAR.

It says to switch it on and put the meter switch on Plate and i should see 90ma of idling plate current with no drive from the exciter, i got ZERO.

Than it says i should advance the drive level of the exciter for 200ma of plate current.  Can't, why?  Because the amp is presenting a 3:1 SWR to the radio and the FT-847 backs down the power output because of the HI SWR condition it's seeing.

If i flip the meter switch to the Rel Pwr position i can see the power output of the 847 but thats about it.  I can adjust the tune and load controls until i'm blue in the face and get nowhere.

This amp was working perfectly before i bought it, and yes i am sure of that, but now i can't get it to do diddly.
