All,
For those with sincere interest in obtaining a 'scope (Tektronics), I
would suggest you contact Mr. Scope - Bob Garcia
(esaro...@bellsouth.net) to see what he has available. Bob is a former
Tek technician and offers Tek 'scopes at very reasonable prices. He is
also quite the gentleman -
I have an HP1740A analog scope (from the 1970's) that is my workhorse. After
40 years in service it still takes a lick'n' and keeps on tick'n'.
Equally importantly, we 'understand' each other.
If one doesn't learn to use a tool, understanding its idiosyncrasies and
limitations, it's not worth b
A nice scope is sure fun to have around the old test bench. Perfectly
good analogue scopes that cost many thousands 20 to 40 years ago are
available for less than a penny on the dollar these days, and are more
than enough for work on HF gear.

Hi Mike:
I'm sure that LED flash is quite normal. Mine has done that since "day one".
I do not experience the jumping temp readings though. A couple of

maybe an RF feedback issue.)
2 - What's your line volt
That's a very legitimate question Fred.
With modern gear containing processors (like the KPA500, K3, etc.), it's
always a good idea to shut it down using the front-panel power switch. This
ensures that the processor gets to do an "orderly" shut down, just as it's
always good to shut down a pc usin
