DANGER PART! DANGER PART!

@Berwhale, a single-cylinder rotary 'motor' or a shaft-driven pump?

I thought it was a clutch until I saw the coils.

I thought it was a clutch until I saw the coils.

I added the 2nd picture a little later. I was reading about axial flux motors and their automotive use when I wondered if they were ever used in turntables, which lead me to the Technics SL-1210 MK7 motor...

Tom Danley posted this at audioasylum. OK, it's not really a picture - but it has pictures and it seems interesting.
Using some seemingly clever methodology to peek inside the Great Pyramid (of Egypt).

RTFM was an asset...

...in the days before 8086... and AP wasn't borne yet.

An in-wheel Axial Flux motor configured as a unicycle would be a hoot!
Upon the next big leap in battery tech, they will be saying "Just add tilt-rotor".
As simple as 4.5.6.

Fantastic. Loses half a star for only having one VU meter, but definitely gets my vote for the most awesome/ridiculous amplifier name ever.

Splendid!

Well, it is what would ultimately be called a monoblock.

SWTPCo had a whole line of "Tiger" amplifiers. Well, three of them, at least. That's the big one.
Predated Jim Bongiorno's Ampzilla by a wee bit, too... at least I think I did.
Full disclosure - there's an Ampzilla hulk in the basement.
(it's a long story...)

Doh. Schoolboy error... Didn't realise it was a monoblock. I reimburse the half star.

Hopefully some film student/audio nerd will make an arc filled movie or anime titled: "Ampzilla vs Tigersaurus. Battle of the Retro Torroids. "

(or not.)

Curious about the "Electrostatic" and "Dynamic" headphone socket outputs on the Ampzilla.

Presumably for different impedances?

Plus : Looks like the small cover in the foreground reads: "Abbey Road Studios"?

 

[mhardy6647]

1) I guess so re: the headphone jacks. I don't really know, though.
2) It's (EDIT) a set of drink coasters (and quite nice they are, too) given to me by my son for Christmas some years back. They serve admirably up in the hifi loft.

This Lindsay's Wheel of Acoustics appears to be 'technical', at the first glance:

IMO: It's just a MOPO (master of the painfully obvious), since it speaks nothing about the acoustics of a 'tree falling in the forest' or the 'butterfly wing-flapping in Osaka'.

+1 and please consider it as a double-Like vote.
I could probably spend 30 minutes browsing those...
