those nasty motor wheel - rumblings.I was actually amazed about how they disappeared behind the not inconsiderable LP pressing and cutting lathe rumble (the latter sometimes audible too), and behind the superb musical information & drive. I ex...

Hi Chris! I accidentally grew up with a Lenco B55 (practically same technology as L70/75/78) and a Thorens TD 124. These were the first victims of my brothers and my audiophile interests - we dismounted and reassembled them. I was more impressed b...

Regarding arm boards and optimal materials, it's very interesting to watch the diverse experience in idler drive plinths. A mixture of natural and slightly lively wood layers, combined with *some* more deadened materials, like *a bit* of MDF and m...

Re/ VTA & gooseneck range not high enough: Having a BSc in audiophilia nervosa including a MSc in empirical material testing... :-)I'd propose a surprisingly crude idea, which might work better than it should. Have a carpenter (or your right h...

ChrisSo just a question. Bass waves are slower than all the others. So why do people put subs X feet behind their mid and tweeter drivers ? Just asking. If I was you Harry I would be very tempted just "temporarily", to set up in near field for one...

a) regarding wiring: I have to try again to photograph - the lighting makes pictures difficult... patience :-)b) Fridge magnets & damping: Drop a circular magnet into a vertical copper tube. An enlightening sight - the magnet centers itself an...

Hi Chris! The magnet damping doesnt't work the way you describe it. What you describe is the magnet "levitating" of the Verdier (and others) by opposing magnets of same polarity.The proposed damping works by eddy current, the same as eddy current ...

Hi Chris! I tried making photographs of the wiring - but the spot is too dark, and the flashlight messes things up – but I'll try again.- It's funny you mention that (even) increasing vertical mass by minimizing & shifting the counterweight ou...

Regarding levelness of tangential vs. radial arms:The side-force on the stylus in a (non-servo) linear tracking arm is proportional to the off-levelness and the lateral DC mass, ie. lateral weight: From 75g up.With a radial arm this lateral mass/w... 
Cartridge Alignment
There are different protractors that differ in the parameters they optimize, mainly how far to the LPs inside the tracking error is optimized. All geometrically "correct" protractors have in common that - independent of tonearm length - they cross...

- Ct 0517: The funny thing with ESLs, Quad etc. is that they do much better with something closer to a current source, this means they deliver much more voltage on high impedance than a low one. Doubling the power in each halving of impedance is t...

Transformer saturation is one of two main loss factors with transformers, magnetic and ohmic losses. The doubling of the power in high power amps with low impedances highlights the problem of ohmic losses. There are two questions about reducing tr...

My LFD MM0 looks like it has the same circuit board as the LFD Mistral, but has a double mono power supply fed by a very generous toroidal transformer. It's switchable between MM and MC, it seems to sound very good on both inputs. I saw that one w...

Regarding EI (there are several other "square" cores BTW) vs. toroidal transformers: Things are not that simple. While a toroidal has the advantage of a more simple "flowing" magnetic circuit, it's main "advantage" is the absence of an air gap - a...

The real fun in research is the reality. It has a certain from time to time recurring character trait of disrespecting the holy truth of any hypothesis. Without that, life would be pontifical s***. :-)Regarding RF: It was only a problem with one p...
