Next, the Amplifier boards are removed for modifications:
- Reduce input gain by 50-60%, to suit higher output from modern digital sources (Roe MK2 and Takman REY metal film resistors, change values to increase feedback, output stage).
- Replace electrolytic capacitors (Elna Silmic II).
- Renew transistors (3 per channel, BC550).
The Quad 33 preamplifier is 50 years old, now.
It was introduced by Quad Electroacoustics in 1967 (to partner the 303 power amp) and 120,000 units were reportedly manufactured over 15 years.
The Quad 33/303 was Quad’s first Solid State consumer preamp/power-amp set.
My Quad 33 is serial no.6184, which means probably late 60s-early 70s manufacture. Continue reading
In 1990, Stereophile’s Dick Olsher declared that the AURA turntable offered:
…..borderline Class A performance….. I’m not letting the Aura out of my grasp. It’s one hell of a ‘table and one that I’d be perfectly happy with until the end of time.

Louisiana people descended from those earliest colonial times were known as ‘Creoles’. Continue reading
The Aura turntable was designed by New Zealander, Dave Whittaker and was manufactured in NZ and Australia over a period of 20 years from the mid 1980s.
This beautiful example of the Aura, is still in use in California at the home of Skipper Wise – musician, recording artist and co-founder of Blue Microphones.
Skipper’s interesting story about his Aura TT tells us also about the affable and gracious man that Dave Whittaker was: Continue reading
Three of the headline acts at the week-long ‘Southern Fork Americana Festival’ in Auckland, New Zealand, 7-16 October.
Hayes Carll is a Grammy-nominated Texan songwriter and Lindi Ortega originally hails from Toronto, but both have ‘paid their dues’ for well over a decade and have a handful of albums each.
On the other hand, young siblings The Cactus Blossoms have just issued their first album Continue reading
The Terminator linear tracking tonearm combines an air-bearing with a (twin) ‘uni-pivot’ bearing.
Uni-pivot bearings need to be stabilised in order to handle the energy generated by a pick-up cartridge.
In this case, twin pivot points were in metal-to-metal contact with the arm-slider ‘V-brackets’ and some instability or ‘bearing rattle’ can be audible at times. Continue reading
