Arguably still the most sublimely uncomplicated and beautiful example of modern architecture sits at the foot of Mont Juic in Barcelona city in Catalunya, Spain.
The German Pavilion, constructed for the Barcelona International Exposition of 1929, was designed by German-American architect Ludwig Mies van der Rohe.
This is our finalised DIY cleaner ‘kitset’ design.
It is a 3-piece ‘kitset’ designed for easy self-assembly, with only 4 screws.
An additional 3 screws attach a slow-rotating BBQ ‘rotisserie’ motor and the whole assembly fits neatly onto the top of a 6 Litre Ultrasonic Cleaner tank. Continue reading
We all know that the small things matter in hi-fi. Especially at the front end of the audio system – eg. the pickup cartridge and tonearm.
The Trans-Fi Terminator tonearm is constructed with a 6mm aluminium ‘L’ Mounting Plate. It’s machined shape and necessary slotted holes, no doubt reduce its structural and torsional rigidity.
Would there be energy loss? Continue reading
I have to say that I’m a little bit excited about this right now…..
Over the past week, I have been testing vinyl records in an Ultrasonic cleaning machine and the results have been all positive.
In the past, I have used a Nitty Gritty record cleaning machine (RCM) and in recent years have acquired an old but well-respected Keith Monks RCM (below). Continue reading
Following Pt I, 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.
In 2008, Dave Whittaker made his last AURA. Incorporating many improvements over 20+ years, his later AURAs Continue reading
