A Line-stage With Output Transformer (WOT) was built back in 1998, a single 5687 tube per channel with output transformer (OPT).
However I failed to get rid of noise (EM pick-up and attenuator switching noise). I lacked the expertise to optimise Grounding and to shield and/or orientate the output transformers (OPTs) properly.
Now, I have been fortunate to acquire a pair of Tango NP-126 Line Output transformers. So, I must re-visit the WOT Line-stage.
Since Feb 2018, I have been enjoying a London Decca ‘Super Gold’ cartridge.
This is a Moving Iron/Variable Reluctance type cartridge – with Moving Magnet level of high output – 5mV.
After a few decades of listening to high-end Moving Coil cartridges, the sound of the London Decca is a revelation. A different sound presentation. No need for A/B comparisons, the London Decca delivers exhilarating energy and power. It sounds more like ‘live’ music to me.
The iconic Rega Planar 3 turntable has been around since introduction in 1977. The most recent editions are the P3 or RP3.
Thus, there are 30 to 40 year old Rega Planar turntables now in need of restoration.
This Planar 3 is from early-1980s, fitted with a Linn LV-V tonearm (and an un-branded Japanese moving magnet cartridge).
The Wand tonearm was designed by Simon Brown (
Design Build Listen Ltd) in Dunedin, New Zealand and was introduced in 2011.
This is a uni-pivot tonearm using Simon Brown’s own ‘defined contact’ uni-pivot implementation, a unique large diameter carbon fibre arm tube and stainless steel metalwork.
This model, The Wand Classic, is a ‘no-frills’ entry-level model with attractive pricing.
Moving Coil cartridge design has not changed fundamentally for 30+ years.
The traditional design of almost all MC cartridges, consists of a stylus on the end of a long cantilever, with a ‘moving coil’ attached to the inner end.
This whole assembly ‘sits’ onto a soft, resilient ”suspension’ or damper’ material and held in place by a rear tension wire.
This ‘integrated’ single-ended 300B kit amp was introduced by Audio Note UK in the mid 1990s. This example was built by me in 1997.
The standard Kit One looks plain and unattractive, so I dressed it up with some Kondo-copper aesthetic!
Not inexpensive (around GBP799 in 1997), this was however a quite good sounding 300B SE amp.
The McIntosh MR71 vacuum tube FM stereo tuner was in production from 1963 to 1969 and retailed for US$399. (Today a good MR71 can still command a price 5 times that!)
The MR71 was the last tube tuner made by McIntosh and, together with the earlier MR67 model, is regarded as the best tube tuner that McIntosh made.
