[Elecraft] PA Transistors Maintenance in K2

[Cameron Francey]

A nice tip which I use when looking for anything in any sort of .pdf manual, Elecraft included as I have accumulated quite a number of them over time is to use the search feature on the .pdf reader.  Ctrl+f on WIndows and cmd+f on Mac and type what I'm looking for.  The index and contents tables are good, but obviously can't have everything in them, so I use the find feature a lot.


Hope this helps.

I vaguely remember reading somewhere that after some number of hours of operation – maybe 50 – the hardware holding Q7 and Q8 onto the heat sink should be tightened, I presume to maintain good heat conduction from the tabs to the sink.  But I can’t find that instruction in the manual now.  Anyone know where I might have gotten that notion, or did I just make it up?

Thanks,

Ted, KN1CBR
