Electronics_101 <> is quite a suitable place to discuss such matters. We also use LTspice (and whatever other tools are necessary or handy, up to and including oscilloscopes and soldering irons) to achieve the understanding.
Donald.
Hello Donald,
Thanks. That's much better than creating a new group.
Best regards,
Helmut

Subject: Re: [LTspice] Re: Kevin -- Tip: a cheap full load resistor
Received and understood, Helumut.
But it would be nice to be able to have a place to discuss this kind
of
stuff. We can get resistors, caps, and transistors, etc. from vendors,
which is supported here, and in fact we have libraries full of stuff
that includes how to get these things. But no pricing info (which
likely changes all the time so it's no biggie).
What we don't have is crosses for various components that are easy to
look up (from comparisons of power, max voltage, gain where
applicable,
etc) and what if a toaster or a waffle iron ends up being a very
affordable cross for a thousand watt 4 ohm resistor.
If we make that a Spice model, would it suddenly be on topic?
I'm not trying to make problems, Helmut, it should be obvious that I'm
trying to make solutions. Sorry if this topic is aggravating to you in
this forum, but if you created a spinoff group and listed it
officially
on the main page, maybe we could share these interesting plug in
compatible, non commercial crosses and save enough money to buy a
gazillion 2n4401's (200 bucks can buy a lot of zits) from whatever
corporate vendors we have spice libraries for.
This is probably the third or fourth appeal to you on this subject of
where we might share this kind of info and you have not offered a
suggestion or a subforum (like LTSpiceFiles).
Can we compromise on this somehow? The folks here are very interesting
and helpful but keeping track of LTSpice forum members that want to
talk
off list is very inconvenient.

BTW, LCR meter applied to Sony SS-5000F speaker showed a *very*

I saw 11.6 - j4.62 ohms. etc.
Cheers.

Be very careful believing what LCR meters say, try disconnecting
the speaker drive unit and measuring that. I predict could be
several hundred uH, or at least a couple
Hello,
Please stop on these threads:

Every further message and many of the previous posting may
be deleted soon due to be off-topic.
