Vintage Audio

So much of that old-timey sound we associate with 1920s music is thanks to the unique (and limited) audio response of the carbon microphone, which was the state of the art for the time.

Here’s a recording of a modern performer singing into a 1920s carbon microphone!

@drahardja I think that the Western Bell telephones we used in the fifties and 60s had carbon microphones. I don’t know if that ever changed for traditional wired landlines. I read that it was this type of microphone that limited radio stardom to tenors, like Al Jolson, and that new microphones allowed baritone crooners like Bing Crosby to become radio favorites.

@drahardja

Carbon mics were used in telephones, apparently until the 80s. I use one in the room for drum sounds.

I moved my turntable from my digital AV receiver to a 70s Pioneer amp that was collecting dust in my wife's grandma's closet, connected to a pair of 80s JBL cabinet speakers from my dad (woofers refoamed 20 years ago). The amp is powerful and sounds great, except the right speaker channel is gritty (bad capacitor?), so until I get it serviced, I guess I'll be listening to records. @vinylrecords

@vinylrecords DUKE ELLINGTON - MASTERPIECES BY ELLINGTON in uncut concert arrangements (Columbia, 1956 reissue). Originally released in 1951, one of the first 12-inch LPs to take advantage of the extended play time with long-form arrangements. Masterpieces indeed.

@vinylrecords OTIS BLUE / OTIS REDDING SINGS SOUL (Volt/Sundazed, 2001 reissue; originally released 1965). Not only did my camera distort the cover, but the left channel on this vintage amp just started cracking up too. Welp, my brief mono record run has come to an end. Hopefully I'll get this system running clean stereo sound soon!

New video! I'm repairing and restoring a 1977/78 Sansui SC-1100 tape deck. Replacing the belts, recapping the boards and doing lots of cleaning and lubrication. Link: https://youtu.be/pgC-ewegKlk #Sansui #VintageHifi #VintageAudio #TapeDeck #Repair #Restoration #Cassette #Tape #SC1100 #VUmeters

In the lab, doing stuff. Bought this deck from a coworker years ago. At first glance, it needs new belts (the old ones turned into goo), new capacitors and some new lights. #Sansui #TapeDeck #VintageAudio #InTheLabDoingStuff

A look inside the tape deck. The circuit boards look very old school, there’s no belts visible in the mechanism.

They took great pride in the fake woodgrain, it seems. #Sansui #TapeDeck #VintageAudio #InTheLabDoingStuff

The capacitor with the leakage visible on top ate its own leg. Thankfully the solder pad was not damaged, just needed a good scrubbing with a glass fiber pen and some IPA. Power board fully recapped now and the deck turns on fine. Next up: replacing the belts. #Sansui #TapeDeck #VintageAudio #InTheLabDoingStuff

Same capacitor on its side with the value of 1000uF and 25V visible. It’s an old school blue Nichicon brand capacitor.
Recapped power board in the tape deck. I used Panasonic FC series capacitors to replace the original Nichicons.

New video! I'm doing some maintenance on my beloved SL-1710 turntable from the seventies. I'm recapping it, replacing the dampening fluid in the tone arm lift mechanism and doing some general cleaning and lubrication.

@janbeta nice! I recently refurbished two turntables, a Garrard DD75 and a Thorens TD160MkII. I quite enjoyed working on them, it was fun.

@davbucci I'm still a bit clumsy and fearful around delicate mechanical parts (especially if they are on a device that I can't imagine living without) but it's incredibly rewarding when things go according to plan with these elderly turntables! :D

In the lab, doing stuff with a 1970s turntable. Delicate mechanics still scare me a bit. #VintageAudio #VintageHifi #Recordplayer #Turntable #InTheLabDoingStuff

New video! I'm repairing a Sony TA-F550ES amplifier from the early 1990s that suffered from some intermittent sound issues. YouTube: https://youtu.be/o3FykCRHAK4 PeerTube: https://makertube.net/w/6vSfkpv8ooSKpJXSJtwACU

Il sortait il y a 60 ans… le Philips EL 3300, premier magnétophone compact !

@thomasfuchs I'm fairly certain that's the model tuner/amp we used here before Dad splurged for our NAD in the late '80s(?). Good machine!
