not unique - I opened one up that was intermittent to find the same...they
have a great cast housing but inside it is pretty disappointing!

> Interesting to learn of the true loss in our connectors.
> Now,  what about our AD switches.  I have several:
> Delta 2's and 4's.  I had occasion to open one following

> Was "shocked" to see that the contact was made when
>  the EDGE of a thin strip of metal was pressed down
> against the flat surface of another strip.  It was at such
> a contact I had experienced an arc or burning do to
> high swr,  I  guess.  Anyway,  the switch became NG.

> I can see why the "warranty" is void if you open the switch;
> no assurance at all that things will all fit back together
> properly when you "home assemble" it back together.

> Ever since,  I have avoided the use of Alpha Deltas after
> my linear,  but still use for rig switching ahead,  etc.
>
> Was my experience unique;  are these  OK for use at power?
> I would like to use one to switch my 259B in/out to check the
> tuner settings after the linear occasionally.
