Klangfilm Style

I'd give my left one for one of these systems. Inspired by American Theater systems but impressive execution.

Dope From Hope - Room Acoustics

I've been exploring the world of proper room acoustics. What if we could build an audio room from scratch? What is the smallest optimal room? Not many clear answers on the web but found many comments on the subject from PWK. PWK considered the room to be second only to loudspeakers in factors to getting accurate sound reproduction. Hear are the instances I could find in the Dope From Hope articles.

1922 Magnavox 35ft Horn

Oh hell yes! A Magnavox 35ft horn with a 12 foot square opening. I'll take two please. Incredible.

The Rockets - On The Road Again

I love a good cover song. They do a good job on this Canned Heat song. I'm in a weird mood today and this seems to be hitting the spot except I'm spinning it on the turntable.


A little history from discogs.

ROCKETS history starts in Paris (France), in the year 1972, when they were known under the name CRYSTAL. In 1974, they changed their name to ROCKET MEN (or ROCKETTERS) as five aliens, bald, with grey eyes, silver skin and space suits, recording the single 'Rocket Man' produced by Claude Lemoine, who would become their producer 'til 1983.
In 1975, they changed their name in ROCKETS and recorded a single 'Future woman'. In 1976, their first LP entitled, 'Rockets' was released in France, and the group launched a series of phantasmagoric live shows which involved vocoder, lasers, coloured lights, smoke and a bazooka fighting flames three . Their following LP 'On the road again' (1978), is released in a large number of countries. The American release was on the Tom n'Jerry label.

RIP Ari-Up :'-(

Just two weeks ago I bought a reissue copy of Cut. I forgot how much I love that album. I've spun it several times over the last two weeks.From John Lydon's website.

John and Nora have asked us to let everyone know that Nora's daughter Arianna (aka Ari-Up) died today (Wednesday, October 20th) after a serious illness. She will be sadly missed.

Everyone at JohnLydon.com and PiLofficial.Com would like to pass on their heartfelt condolences to John , Nora and family.

Rest in Peace.

Klangfilm Europa Junior

Klangfilm the Western Electric / RCA of European theatre systems. They built amazing horn systems. I like the jumbo systems but here is a modest size Klangfilm the Europa Junior. Odds of finding one of these in the southern US is very slim. I love industrial art.

Altec Lansing Duplex Speaker

I actually found one of these cabinets in an antique store last year. It had been gutted and turned into shelves with a little light shining from the top. Very poor shelves. I asked the owner of the store about the guts and he commented that he tossed all that old stuff into the dumpster. I was too late. It was all I could do to just walk out without being a smartass.

Scully Lathe

Just file this under irrational techno lust. The skully lathes are so cool.

The above may actually be a Neumann lather.







Thanks for the comment wbhist.

The Scullys of the 1950's and '60's (as on the 4th and 5th pictures shown) are my preferred variant. Lead-in grooves had spacing dimensions of 32.3125 and 7.625 lpi, with some having a "medium" spacing of 15.583333... lpi and most others' "medium" spacing being 14.7291667... lpi. Such lpi dimensions also applied to "spread" grooves that transported between one "band" and another on an LP record; and the 32.3125 and 15.583333... (or 14.7291667...) were used for "catch" grooves that came after the lead-out but preceded entry into the locked groove (this, I'm told, for the activation of automatic record changers). As for lead-outs, depending on what lathe was used by which studio, there were "slow" and "fast" moving turns, grouped as follows: 4.62 and 2.3 lpi; 4.17 and 2.14 lpi; 3.92 and 2.04 lpi; 3.83 and 1.98 lpi; 3.69 and 1.92 lpi; and 3.48 and 1.83 lpi. Those are the lathes with the knobs that turned anywhere from 70-400 lpi, or 105-600 lpi, or 140-800 lpi. Lathes as so constituted appear to have been manufactured as early as 1950, so I'm told.

The earlier lathe with a gear box as at photo bottom, its design dated back to c.1938. The lpi dimensions as shown were 88, 96, 104, 112, 120, 128 and 136 lpi. In this configuration, there were other sub-classifications. Columbia in New York had a lathe (in use from c.1939 up to August 1966) that had groupings of 150.1875, 163.6875, 177.1875, 190.6875, 204.1875, 217.6875 and 231.1875 lpi; while Aardvark Mastering's ancient Scully's finer grooves are 178, 194, 210, 226, 242, 258 and 274 lpi. Then there are even finer groups, with the "coarse" being 132, 144, 156, 168, 180, 192 and 204 lpi (plus, on Columbia's aforementioned cutter, 225.28125, 245.53125, 265.78125, 286.03125, 306.28125, 326.53125 and 346.78125 lpi).

As to the lathe on the top photo as originally on the cover of that Electronics World magazine: Looks suspiciously like a Neumann AM-32 to me.

Paul Voigt By Percy Wilson Nov 1965

This is a great article on Voigt. I need to find the rest of it though. Hopefully to be posted soon. If you have it please share. Yes I intentionally left the name Edison off of the title of this blog post. I won't go on that rant here.

Hartley Little Known Speakers

I've never heard of Harltey speakers but they look interesting. I want to play all my music from aquariums from now on. :)

Retro Hi-Fi Girl Friday

Thanks Thebes for sending me this one. I have to wonder about this one though. Not exactly retro but hell good enough. Tall girls in high heels navigating tube amps to play records. Wait what was I saying?
