Is vintage audio better than modern releases? (post 2000)
This reminds me of the first argument I had regarding the merits of mechanical VU meters over LED.
Yeah, we like vintage stuff, especially with those big VU meters. Hell, I was looking at the specs of the Pioneer SX-1980 the other evening and thought what a beast this must have been in the 1980s. At 270W this is certainly by no stretch of the imagination much in modern times thanks to PWM, Class D and mounted on a one inch square heatsink.
The Sony vintage TA-F444ESX – protector and regulator failure
As a follow up to our previous article on speaker protection we thought it pertinent to look at this classic vintage amplifier, the Sony TA-F444ESX. Good in looks, solid in build and of course exceptional audio.
So yesterday evening you switched off your sound system and today it shows the dreaded “protection” warning. You check the cabling for shorts, open circuits and tear the unit apart hoping to find the offending gremlin. Reassembly and it works, bingo – you didn’t find the problem – it must have been a loose wire.
For those born after 2000 and electric motor is seen as just another product of technology, just like the cell phone. Electric motors have been with us for the last 200 years, personal handheld phone (Motorola and Martin Cooper) about 50. There is a link of course, that being switching devices.
Although it is an accepted fact that inverters and variable frequency drives are with us to stay, older technology relied on some pretty innovative ideas to increase and/or lock an electric motor’s speed.
