I got 2 components, mystery number 1 is on the left, it has a black package, with a greenish epoxy, and has 4 leads coming out of it. mystery number 2 is a green, capacitor shaped object, but has a cylindrical item sticking out of it.
these components came from an old sanyo television set (gaint wooden ones.)

any input on what these are is much appreciated.

the big black item might be the Voltage Multiplier on the high voltage side of things (judging by size, the need to epoxy the thing, and the thick wire coming from it)

The small 2 wire part may be a coil and capacitor network. Old TVs had video peaking coils and traps but the coils were fragile and not easily into pc assemblies.

If you could sweep it between 3 and5 mhz that small part it might reveal what it did.

Also if you preserved the model number, serial number, and chassis number, you could ferret out the service manual from Sams photofacts. A good habit to get into if you retain parts from old stuff is to log all numbers to identify it. Without information it is just junk.

In those old sets, beware of the white thermal paste on parts.
Tv's are a good place for things to incubate in for years and years. What back in 1968 would like to jump into *your* lungs today.

NOW YOU TELL ME THIS?!?!
that would have been usefull information a year ago, when my hands were black with dust, and covered with all sorts of nasty grease...

the only information I got on the part was the numbers writen on the thing: "PH45 - E", despite searching the net, I could not find a datasheet or anything even close to resembling it,
radiotech, this was the same TV I got the AL magnet wire from.

75% of the TV I returned to the dumpster, the heatsinks with some warning labels (and perhaps serial numbers! XD)
are now in the dump somewhere, (those were gaint AL panel heatsinks, about 1/16 of an inch thick, 1.5 foot by 2 foot.
different shapes, lots of surface area. attached to them were some very powerfull transistors, with a clear plastic cutout the shape of the transistor that was smeared with grease, (the grease literly covered most of the transistor.)
I also got some PP capacitors, big ceramic disk capacitors, and wide variety of pots and shiny knobs...
unforchunatly, I killed some of the said transistors, and got rid of the AL wire, as it was hanging on the wall collecting dust.

I took apart dozens of old TVs when I was a kid/student and it never killed me! Maybe vacuum out the dust before you start, though.

The worst are those old tube "table radios", they can have an inch of dust inside, and they don't smell nearly so good once you've cleaned it out. I'm considering selling it on Ebay as OMG LOOK RARE VINTAGE dust.

One issue with tube stuff, especialy TVs, they did get cleaned by the service techs as part of the regualr calls to change tubes. I packed a hugh tube caddy in one hand and a Jackson 648 tube tester in the other, for balance, on the climb up 2, 3, 4.. flights of stairs in the older parts of Montreal too long ago..

When solid state sets came out, they could run for years without ever opening the case, and depending on the home, and how it was heated, collect years of dust, and "critters". And that thermal grease, in the first days of power transistors always came with warnings. (Be compounds)

My oldest antique radio had spent many decades in a barn, gathering more than a little dust.
The case was packed with a literal rat's nest - including little mummified rats.

Beryllium oxide, "Beryllia", is the carcinogen to watch out for in old thermal compounds or transistorbacks. Should be OK if firmly gooed in; you'll see it in a lot of gas lasers for its thermal conductivity. Just don't make dust, and try not to hoard too much crap from old TVs. MRSA loves that fungus and muck that grows inside!

They're great in the wok or microwave steamer. I inherited a crunchy one in the bottom of a Viscount organ. You can take the organ out of the rat, but you never get the rat out of the organ! Before I sold it, I resorted to spraying all the interior surfaces with polyurethane lacquer in an attempt to "seal in" whatever could not be purged with air.

If that dust in any way resembles Jeasus or Oprah, youre going to be an extremely wealthy individual!
I dont remember what that slice of toast that resembled Jeasus went for but it was a LOT!!

I practicly have a hoard of electronic goodness,

one thing that I have recently took apart was a 5-15 year old APPLE computer/monitor built into one.
there were so many ferrite chokes... underneath the monitor, was were the harddrive and motherboard were housed, and above it some type of fan assembly, I got over 10 ferrites from the mother board alone,
from the CRT driver and other crap inside, I got some power mosfets (mostly SSF9N80A)
powerfull bridge rectifiers, some 1kv tantalum capacitors (yes 1kv) and torriod heaven, about 5 or so farrite torriodal transformers crammed into one circuit board.

In totallity, I collected over 25 pieces of ferrite assorments (transformers,torriods, chokes...)
a functional RAM, a nice heavy pile of components, and more then enough new looking goodies to last me for a while
(there was very little dust)

I hope one day, Ill have the oppurtunity to go through those really old 5 ton computers that had cabinets crowded with transistors and over 5,000 vacuum tubes.
personally I like the old outdated components, there are just too much fun.
