The Golden Age of Hi-Fi (ladies-of)

Images of women as depicted in high-fidelity guidebooks circa 1960.  These sort of publications generally deal in DIY advice, schematics, and ‘buyers guide’ segments.  There is a lot of floor-sitting, demure outfits, and distant-gazing.   There is an uncanny similarity to many of these photographs.  Or as E puts it:  ‘WTF.  They all look like cats.’  Yeah that pretty much says it.

 

On rare occasion, we are shown women in more active (IE., less decor) roles.  Here are a couple of examples:  the (potential) technician and the shopper.

Mono Pilot Hi-Fi Console System circa 1955

From PS Dot Com reader C. McColm come these images of his original circa 1955 Pilot mono hi-fi system.  I take C.M. at his word when he relates that there was a cult for Pilot in the 1950s; this website gets an unusual amount of traffic from individuals searching for, and reading, the few PILOT articles I have posted.

Pilotuners were made for a very long time, in many configurations; I’ve personally bought two in the past year alone.  Complete 1950s hi-fi systems like C.M.s are rare these days for many reasons, not the least of which is the fact that many have been cut up and gutted for parts over the years.  It can be hard to find the space to incorporate a unit like this in a modern domestic-space, but for anyone who enjoys listening to 1940s and 1950s recordings, I can’t imagine a better way to hear it than on a system like this.

C.M. relates:

‘ALL PILOT electronics; Pilotuner tuner/pre amp, Miracord Auto Turntable.  Williamson Amp with a pair of Genelex KT66 tubes … Great sound: like you are really there. The Pilot pre amp tuner has adjustable AFC for the FM, EQ for the phono; roll-off  and turnover frequencies and a setting for early 78s; if you have 78’s, you need this eq setting to hear them properly. The built-in speaker cabinet is ported and bass reproduction is clear and solid. The High end on the triaxial speaker is great also. Speaker is branded University Sound; (this was) a division of Altec. Huge speaker with L-pads for the mid and high frequency drivers.

    ‘ This console, with the original Goodmans Speaker, won 1st place in a hi-fi show in NY city. My friend’s Father assembled it .This turntable has a Magnetic cartridge . A lot of systems then were (considered) hi-end if they had a Magnetic phono input . It has both LP and 78 needles switch-able without removal.’

‘This set sat inoperative for a long time . (I performed) a complete cabinet restoration, replaced a fuse, and cleaned the controls. This set really gets the job done. Pilot was really HI END; it was not as popular as Fisher or Marantz or Scott. People in the know knew about this stuff.’

Hi Fi Amplifier Schematics c. 1954

The Craftsmen C-500 power amplifier

Today we have some hi-fi amplifiers from the mid 1950s to look at.  Many of them use unusual output transformers with split primaries, so I am really not sure if it’s even possible to build these designs today.  The Craftsmen C-500 pictured above uses a standard PP-VC output transformer; it also uses readily available, robust 6SN7 and Kt66 (aka 6L6) tubes.  Check out the circuit in the output cathode bias; even though this is a cathode-biased amp, there is a provision for adjusting the overall bias, as well as a balance adjustment ( to allow the use of unmatched power tubes).  Here’s a few more…

Bogen DB15 schematic

General Electric A1-300 power amp.  This is a good simple design that will provide 12 watts.

The Leak TL-10 amplifier

The Quad II pre-amp and power amp.

A DIY hi fi preamp design from 1954.  Note the very sturdy parallel-cathode-follower output (the 12AU7 section).  This could probably drive a 10K load pretty easily.

1955: Japan Goes Hi-Fi

Download a three-page 1955 article entitled “Japan Goes Hi-Fi” as originally published in AUDIO magazine.

DOWNLOAD: Japan_Goes_hifi_1955

The article concerns an early Hi-Fi show in Tokyo.  Postwar Japan had sufficiently moved beyond the subsistence level to indulge in luxury-leisure pursuits; soon Japan would come to dominate the world in the electronics field.

The ‘hi-fi coffee shop’ pictured above may seem like a quirky anomaly, but you would be amazed at the sound systems on display in even modest Japanese bars and restaurants.  The last time I was in Japan, we stayed at a bed and breakfast in the mountains of Hokkaido; upon arrival at the inn, my jaw dropped when I saw that the sound system in the lounge consisted of a JBL Paragon speaker and huge McIntosh tube amplifiers.  It’s hard to say exactly why this trend developed, but if you spend any time in Japan, I think it’s clear that ‘excellence’ in general is an important concept in Japanese culture.

Above is a 1955 advert for The Panasonic.  Not ‘a Pansonic,’ but THE Panasonic.  The Panasonic was a single product introduced for the US market by the Matsushita corporation: an 8″ full-range hi-fi driver.  Panasonic would soon grow into an entire global electronics brand, second only to SONY as an ambassador of the Japanese electronics industry.

Here is a 1955 review of “The Panasonic:”

Bozak Compact Speakers of the 1970s

Download the four-page circa 1975 ‘Bozak Compact Speakers’ Catalog:

DOWNLOAD: BozakCompactSpks

Catalog contains photos and specs for the Bozak Rhapsody, Tempo II (Tempo 2), and Sonora speaker units.

Bozak is another important chapter in Connecticut audio history.  The famous manufacturer of legendarily large home hi-fi speakers was based in Connecticut for the entirety of their 30-year heyday.  Pennsylvania native Rudy Bozak set up shop in Stamford in 1951,  later moving to South Norwalk and Darien, with operations in several other towns.  Wikipedia has an excellent and thorough treatment of Bozak, the man, his myriad technical innovations, and the long history of the company.  No need to re-tread those waters; I will add this though: growing up in Connecticut, enormous 225-lb Bozak Concert Grand loudspeakers were a memorable site in the homes of some of my friends; a room-dominating testament to the intensity of a largely lost culture of audiophiles.

AKG K-340 Electrostatic/Dynamic Headphones c. 1979

Download the six-page color product sheet for the venerable AKG K-340 headphone of 1979:

DOWNLOAD: AKG_K340

The AKG K-340 (not to be confused with the modern AKG K 340 earbud) was AKG’s top of the line headphone of the 1980s.  Introduced in 1979, the K-340 took the basic design of the classic K-240 (which was very sophisticated in and of itself) and added the additional complication of a separate Electrostatic driver and associated crossover network.

 

 

 

 

 

 

Wikiphonia has a detailed entry on these unusual headphones, so no need to re-tread those waters; the six-page document I post here is some new material for the web, though, AFAIK.  Check it out…  and if anyone uses these cans, LMK yr thoughts…

Fostex RP Headphones 1977

Download a high-res scan of the four-page 1977 Fostex RP Headphones catalog:

DOWNLOAD: FostexHeadphones1977

Models covered, with specs and photos, are: Fostex T50, T30, T20, and T10 headphones.

On-the-go music-listening is more popular now than ever due to the convenience and features offered by devices such as the Apple iPod.  This new technology has also driven the demand for quality headphones.  When asked for headphone recommendations,  I generally steer people towards the Sony MDR-7506, due to their relative portability, extremely low impedance (translation: even an iPod can make them very loud) and very present sound.  Plus they have a 1/8th-inch jack, so they mate properly with your iPhone iPod or whathaveyou.

This all being said, I always also tell folks that I personally do not listen to music on the MDR-7506.  They are too hyped and unrealistic-sounding to me.  I am not sure exactly what they do to the sound, but they make everything sound ‘better’ in a way that i don’t really find ‘better’ but instead somewhat cloying.   Regardless, if you want headphones that will play loud, shut out the outside world, and last forever, the 7506 is a great bargain.  This is also why almost all musicians prefer the 7506 in a recording-studio-tracking situation.  I own several pairs for this reason.

What I use personally for monitoring in the studio is the Fostex T50RP.  When I am tracking I find the 7506 to be the best choice, but whenever I am behind the desk and need to monitor with headphones for one reason or another, I put on the T50s.  Likewise, they are good for music listening at home.  They give a good, accurate sound, and they are just so robust and well made.  These things really are the best value in audio today.

Turns out that the Fostex RP line goes all the way back to 1977.  The components have changed a couple of times over the years, but the basic printed-diaphragm technology which distinguishes the RP line from most other headphones has remained the same.

According to the excellent ‘Wikiphonia’ headphone web database, the RP line was originally introduced as a less-fussy (IE, no power supply needed) alternative to the then-novel and popular Stax Electrostatic headphone line.

Pictured above is the Fostex T20 as it first appeared in 1977.  The T20, like the T50, is still be manufactured today in a slightly varied form. The T20 seems to have undergone the least cosmetic change since its introduction.   I do not recommend the T20.  I have owned a few pairs and I find the very dull and chalky.  My advice: spend the extra 20 bucks and get the T50 instead.

Pilot Radio Corp Hi-Fi Line Circa 1962

Download the entire twenty-page 1962 PILOT hi-fi catalog:

DOWNLOAD: Pilot_HiFi_Line_1962_Catalog

Models covered include: Pilot 610, 602MA, 602SA, 654MA, and 746 receivers; Pilot Mark III, 280B, 285, and 780 FM tuners; Pilot 230, 240, 246, and 248B stereo integrated amplifiers; Pilot 200, 120, and 100 FM Stereo Multiplexers; Pilot-Garrard RC-3, RC-5, and RC-4 turntables; and Pilot PSV-2, PSV-3A, and PSV-4 speaker systems.

When you think of //Long Island City/Audio History//, what comes to mind, if anything?  Likely Fairchild and Marantz.   Pilot made neither pro-audio nor true high-end hi-fi, but as the graphic above reveals, they had quite a deep and storied history.   I have only one PILOT piece in my audio-pile (never say c%!!&ction) – an early stereo extension speaker – but I would bet that some of these pieces are pretty decent.
