Re "MRSA loves that fungus and muck that grows inside!"
You are a lot more likely to transfer MRSA to an old radio than it is to transfer it to you.

Lots of fungal spores and general dust might be a problem but these things ran hot and dry. old sheds are wet and cold.
Bacteria like warm and damp.

In regards to the small Murata-like package: they are coil-cap network, I've pulled one apart at one point.
Maybe they could be used in a pi filter for a if system. (Nudge nudge, wink wink)
And critters, I could tell a story about a rat and a MO. But this is a family website.
[Edit, The black epoxy filled device is a tripler for the EHT supply which feeds the picture tube.]

About 4 days before this thread started i broke one of those things like you have, and tada! Inductors. Mine had 4 leads, 3 inductors, and i did not see any capacitors, but seeing that they would be so tiny, i did not care to look any further.

Mine had a tiny ferrite core, it was so cute... It was small enough to consider it a crumb of ferite from a broken LOPT core :P.

so you say, that if I desided to open up that little green thing, Ill find a baby torriod?

I also found some multi lead packages along on the same PCB that had about 10 leads, they were a potted resistor string, in the same manner as the green one, but red.
each resistor (lead after lead) was about 100ohm. and there was about 10 of those leads, so 2 lead is 100 ohm,
3 leads (1st and 3rd) 200ohm and so on so forth.

by the way, about the rat, I saw the pictures on the net, the rat's head was stuck in the line filter's terminals,
I once found an army of dead flies (I think about 50 of em..) inside a mini fridge someone threw out.

while I never took the fridge home, (and certenly wasn't planning too), I happened to have my trusty multibit screwdriver with me, and took the back cover off on the spot(1 person spotted me and gave me a wierd look)

I was in it for the fan and compressor (also found a 330uF start capacitor)
I work fast though, I can remove the covers of an MO, rip out all the guts, and then bolt the cover back on after extracting all the goodies (yes magnetron, MOT, everything) in under 4-5 minutes. so usually no one notices.

Old fridges often have intact freon loops. In our area they need to be purged by a HVAC tech with a license to collect and store gas. Then they mark them as scrap metal.

My story involves a rat which was de-spined (Making words is fun isn't it). And maybe the capacitors are a result of
the coils proximity.

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.

Hmm that dragon, is that your work? Impressive.

yeah... just a quick drawing that I haven't bothered finishing, I have other hobbies other then HV and electronics, although electronics and HV is my major hobby. (and always will be)

zues, I want to hear that story.

I'll oblige. There was a microwave oven brought in to be repaired which woudn't cook. So the cover was removed and
guess what was there, the rat's body was cooked away so there was only the skeleton left at the back.
However the front end was untouched (except it was dry). This is a bit off topic. Hobbies, HV is my hobby and
hopefuly my career (I'd like to get into high power RF servicing, you know TV towers and the like).

Eh one time I took apart this old tv that I found alongside the curb and it had literally thousands of dead bugs in it. I mean they were piled like an inch thick all long the bottom and on the PC boards. At that point I said "screw it" and threw the tv back into the garbage.

I've taken a LOT of old electronic stuff apart and this is the general order of 'fun' to 'not fun' as far as I'm concerned.

Most fun:
-Old tube TV's and Radios. They're always an adventure and you find tons of valuable vintage parts in them like quality power transformers, vintage resistors/caps, tube sockets, AC FLYBACK transformers and of course VACUUM TUBES. Unfortunately it's getting quite rare now to find old tube electronics lying around.
-Microwave Ovens. Grab the MOC, MOT and magnetron and give the rest to scrap metal. Done.
-Computers. Good heatsinks, power supplies, RAM card, fans and other useful stuff.

Not so fun:
-Modern CRT TV's and Monitors. Basically I just take out the whole main PCB with the flyback on it, the speakers and the degaussing coils and throw the rest away.
-Modern VCR's Stereos etc. Not many useful parts in them.

Least fun:
-OLD transistor televisions and electronics. These things are normally an absolute dust mine because they've never been opened/maintained unlike vintage tube electronics. Also they're a nightmarish mess of tangled wires with like 20 random driver boards and stuff.
-Printers....Uh don't even mess with these. Great way to ruin your cloths with ink/toner and they don't contain any parts that are even remotely useful.
