Fried N-Gen - what components to reorder?

[Andrew Moore-3]

I accidentally transmitted into my Elecraft N-Gen wideband noise
generator and now it doesn't generate noise.  Surprise, surprise.

I assume I need to replace the MAR-1.  As long as I'm ordering, what
other parts might need replaced?

Andrew,

Replace the MAR-1 and, in all likelihood, everything will work just
fine.  Of course if the power level was quite high, you might want to
look for charred components.

I have done that 'stupid trick' several times myself.  I try to put the
K2 into CW Test state as a precaution, but sometimes it 'just happens'.

Hi Andrew,

An alternative might be to build N0SS Tom Hammond's noise gen circuit
that you will find on his web site and also on the Elecraft site.  It
uses a zener diode, a couple of 2N2222s and a small handful of passive
components.  I built one up on perf board last weekend in a couple of
hours, and it works really well.  You don't need a printed circuit
board, ugly style or "Manhattan" construction is quite OK.
