Check out the local Fry's electronics. Not that they have that
great a selection, tho. It depends on what you want.


I'll 2nd the request. Any good places near L.A.? Fry's only carries
some NTE parts. Signal Electronics in Torrance carries even smaller
amounts of NTE, but also has a few dozen JameCo.com and an equal amount
of Philmore parts; i.e., nothing to brag about. Torrance electronics
seems a little better in some areas, perhaps harder to find NTE &
JameCo parts, but has less over all unless they're hiding them behind
the counter; e.g., just found a Sample & Hold chip at Torr. Electronics
that Fry's and Signal only have in their dreams.

Isn't there anything in the entire L.A. or Orange county? Something
like a nearby Digikey would be outrageous! :)

Electonic City in Burbank tends toward broadcast equipment but has a
fair number of semiconductors 1N, 2N,'LS and such, cable, connectors.
Also try ITC and Ametron. Panther parts (No Hollywood) has lots of
capacitors. TAW in Burbank has 1% resistors. Digi-Key is as near as
your phone.

Irritating isn't it? 2nd largest metro area in the country and you KNOW
what you want is here SOMEWHERE -- but WHERE???

All of those parts were originally from INTEL. NEC was a second
source. What type of RAM does it use?

8155 contains a "small" RAM 256 bytes
Suffisant for the stack and some data.

Another saved RAM is probably located on another board

I've never used the 8155 and don't think I have a datasheet in my
collection, so I wasn't familar with it.

That's good to know about the 1% resistors. I guess there's always
micro pots. Does Panther also have precision caps? Decades ago there
used to be a ITC in Torrance. Loved the place. Back then it was a sort
of surplus of electrical parts and equipment. I remember them having
boxes of old ferrite rods taken from radios. I see they're out in L.A.,
very cool.

BTW, Radio shack seems to have a nice little parts lists.

Back to basics here guys.

I am referring to a terminal strip like this.
http://www.ledlight.dk/images/samlemuffe400x320.jpg
It may be 3 amp or 5 amp or something similar to that sort of low
capacity.

snip

The way I would love to do it is to get some sort of crimping tool and
put a small brass collar over the wire and squeeze the collar on
securely. The brass would be tough enough to resist the screw doing
any
real damage.

What do you find is the best?

I bought an assortemnt of sleeves and a crimping tool,
to instrument cars,etc.
Not only it solves the fraying/breaking wire problem,
those sleeves also retain a little bit of the isolation ,
so that even if you have to move about the strip/circuit
quite a lot ,wires do not tend to disconnect,and things
look a lot more professional.
You have 2 type of sleeves, metal only, or a small piece
of coloured plastic extra.
The last ones give most protection.
(And you get coulour coding thrown it for free).

That would be my favoured way of terminating the wires, as well. I seem
to
think that I've seen these things referred to in a catalogue, as "
bootlace ferrules ". I'm never in favour of tinning wires prior to
securing in a screwed terminal, for two reasons. First is the oxide layer
that readily forms on the surface of solder, which may lead to a
resistive
joint in time. Second is creep of the soft solder, which over time leads
to a loose screw. How many mains plugs have you opened, and found that
the
manufacturer pre-tinned leads, are virtually falling out of the plug
pins,
with the screws so loose, you could undo them with your fingers ?

Arfa

I agree totally that soldered wires should not be put into any sort of
screw
terminal. I have learnt that the hard way: A long time ago I wired a lot
of screw terminals after first soldering the ends of the wire, and a few
years later I found that the terminals were loose and in some cases the
wires had fallen out. If the wires were carrying current, they could get
hot and start a fire. If they were for earthing etc. this could also be
dangerous. I had to rewire the whole lot, without the solder.

I wonder if this will be the same with lead-free solder. I would rather
not
try it on anything important.

By the way you can buy screw terminals which have a flat piece of metal
that
clamps down on the wire instead of the screw itself. This avoids damage
to
the wire but the terminals cost a bit more. I would suggest buying the
better terminals if this sort of thing interests you.

If you use crimp-on ferrules, make sure you have a really good crimp tool,
because I have seen wires fall out of poorly crimped terminals. The one
common characteristic of all good crimp tools, it seems to me, is that
they
cost at least a week's wages to buy.

Chris
my last quality set cost Ł50, you either need a pay rise or some instruction
on
how to use them correctly.

about anything seems to dissolve them.

Alcohol is not considered a "solvent" for any plastics, metals or
epoxies used in electronics.
It makes for a fair cleaner to remove grease and oils..
The strongest solvent I ever came across here was MEK (methyl ethyl
ketone if I recall correctly). Smells very much like chloroform.

What did you expect? This is DAK, after all, the guys who used to sell
reslit instrumentation tape for audio recording. The guys who sold
fibreboard subwoofers that vibrated themselves apart. To be honest, I
didn't know these guys were still around.


I was told it would pick up sound from 100 feet to 100 yards away but
it hardly picks up sound from 1 metre away.


You need louder sound sources, then.


If no one has a solution then could could someone suggest a reasonably
priced microphone for filming.


What does 'reasonably priced' mean? If you're looking for a good cheap
boom mike, there aren't a lot of choices out there, but Audio Technica
would be a good place to start.

Probably true, but if it's as grubby inside as the OP indicated, he
might have some (cooking) grease fallout in there, and might want to
properly clean around the HV parts, using care not to zap himself...

Try the dust removal thing first.

I wouldn't use any solvent, some solvents will disolve the aquadag (graphite
coating) off the back of the tube and you don't want that dripping all over
the EHT circuits. Better just blow the loose dust out, and maybe give it a
light and careful brushing (with a plastic handled brush if you're afraid
of the EHT).
Not only does it have the chance of getting onto circuitry, it also
changes the capacitance of the tube wall, changing the circuit for the
CRT drive elements as well.

I think so, at least on some brands of tube. Can't remember for sure what
solvent I was using but I think it was isopropanol. It was a scrap set
anyway so I didn't mind too much.

Thanks for replies. I wanted to conclude that Torrance Electronics
seems to be the best in my area. Initially they may appear small, but
behind the counter are rows of shelves filled with parts. Over the last
month I've taken numerous lists of parts ranging from sample & holds to
discretes. On rare occasion did Fry's and Signal Electronics have them,
but in every case Torrance Electronics had every part.

.... my 2 cents. Just thought I'd give Torrance Electronics a free plug
and A+ as far as retailing is concerned. I have no affiliation with
Torrance Electronics.

All Electronics in Van Nuys and C&H Surplus in Pasadena have common
hobbyist parts and a real good selection of consumer and industrial
surplus (aka "junk").

Marvac Electronics stores are in the region, they mostly do
repair-oriented stuff but they are more than just ECG/NTE.

Nothing like the selection available overnight from
Digi-Key/Mouser/etc. though.

Any preferences between Digikey and Mouser? I'm looking for a 2SK170
fet. Mouser returns two transistors and claims they are a cross
reference for 2SK170, but they must have some bug on their site because
both parts are diodes. Digikey on the other hand returns no results.
