odd audio amplifier that isn't
Quickly,
Picked this very heavy thing up the other week for the singular reason of wanting the brass hex bar handles, as can be seen in the final photo. I
assumed it was a defunct amplifier. When i got it back i opened it to realise that whomever made it was just using the casing and heat sink of a power
amplifier. The pics following and the insides, anyone have an ideas, the transformer it a torriodal RS components number, 240-120 i think.
The entire thing had lead sheilding inside and out.

Not that strange.
A strange amp is one that amplifies in both directions.
I know they told you in school that amplifiers only work
one way, however, the problem is that when you give
an engineer who doesn't know the rules (in this case a
female carbon based unit) a job — they invent things
that shouldn't exist!
Lead case? Perhaps it came from a Tempest computer.
Bunch and half years ago on ye old NY Cities Radio Row
I bough a 1200 or 1500 VDC US Gov surplus power supply that
had a brass chassis. My thought over the years is that is was
used in a mine sweeper — who knows.
By da - it had a mechanical crow-bar switch that worked
when la power supply was removed form its rack or same such.

Sure looks like an audio amplifier: matched pair of circuit boards, polystyrene caps, power
transistors in sets, big-can filter electrolytics, ceramic-case power resistors, even the toroidal transformer. Toroidal transformers are common in
high-end audio gear because they greatly reduce stray magnetic fields from the transformer. That all said, it looks like a shop-built amplifier, not a
commercially-produced unit.

Ahh my mistake was that i hadn't ever seen inside an amplifier before, lol, well i still have the brass handle to use on something, maybe a door.
thnx very much

The transformer in it is worth a lot. Very well designed, a work of art and many hours by someone.
