Mystery components and cool ones

[momo]

These were part of the score, some, you tell me, I have no clue!
Other like that old transfo is nice.

Great score!  Some radio stuff in there (IF transformer and so on) but mostly VERY useable stuff!  I am jealous!   

I want a triode socket like the octal one above, that has screw terminals.

From this you might be able to scrape-up some more data:

That looks like one of those CRT boosters that they used many years ago to enhance the picture on failing TV CRTs.

Yes, it was a hack fix that was frowned upon as it quite often didn't solve the true problem.   From a modern perspective it increased the X-rays from the tube.   Compare that to later CRT computer monitors and TVs which detected the HV getting too high and shutdown the monitor in order to prevent high X-rays!

AD2006 was a now-$9 digital voltmeter which sold for well over $300 when new.

Guardian is a solenoid. Hook it to 12VDC, it will suck-up the core. Hook it to 24V it will suck-up pretty seriously, like tape-deck control.

#2 and #3 are transformers. The square can is obviously a radio IF transformer. The Bakelite job may be an audio transformer, but the labels are unclear to me. Being "intervalve 1938" it is surely >100K impedances and 200-5kHz bandwidth.

It should be possible to get data on that one.   Guardian is a US company (I think they are still operating).  I worked on a project which used 1000's of their solenoids.  The solenoid is highly likely to be DC.  The plungers have shape options.  The shape trades a stronger force when extended (conical) with stronger force when closed (flat).

the general rule with those style Rifa caps is - if they have any cracks or crazing, chuck em away. if no cracks, chuck em away.

I posted a link to Kelco who operates Guardian now.

Momo's picture says 24VDC on it.

I think Momo can take it from there.

So, is that because you want them?, 
or are they really crap?!

I will sell those as I don't need that.

This was used as crossovers?,  and the ability to increase or decrease high end via the switches.
heavy current coils it seems.

[momo]

Look at these beauties,

I don't know why I think of Saddam Hussein and his golden toilet.

I don't have any info on these..

Yep, looks like Guardian still exists but under Kelco.   I didn't get a hit on that part number.  1974 I suppose you need an old catalog or advert.

Sure looks like it to me.  I'm not sure what it's origin is.   It's not DIY that's for sure.  Commercial speakers don't have history of putting values on the inductor.   Also, the inductors also have part numbers.  I was thinking perhaps a DIY speaker kit but ...

A bit of poking around for the inductor part numbers got me to: Wharfedale Dovedale 3-way crossover.  So commercial speakers

Wharfdale is a very well known HiFi speaker company from the UK.

They made some really cool looking chips in the 70's.

Lot's of cool stuff in that score by the way.

I can't find any info on this, it looks like a transistor to me..

[duck_arse]

possibly a resonator or filter. what's the other face look like?

[momo]

Nothing else on it.

I found many of these mixed in with 1/2 watt carbon comp resistors.
Mini inductor?
.2 ohms from automode on DMM

Probably a rectifier or 2xdiode array.  Check with multimeter for the presence of diodes and how they connect.

The common set-up is a common terminal and two diodes point towards or away from that common terminal.  However, back in the 60's companies offered all sorts of arrangements.

Short the DMM terminals first to get a reading for the DMM leads.  Measure the part, then subtract the DMM leads.
Good chance they are 0.1 ohm or so.   

Not sure those parts are off the shelf or someone made them - very common to DIY low valued resistors by windng resistance wire over other resistors.

They look to me like power supply remote sense resistors..
