Asian Spice Restaurant


At your risk.


I cannot remember exactly the name, it is in Liosion Street in Athens, near Stathmos Larissis metro station. Just had a so nice vegeterian meal. So great warm taste and hot spicy with spices added just after withdrawing  the fire from the pan for keeping the vitamins.


At excellent price compared to food quality. Just 3 euros. The kind people from Bagladesh even offered a thin sliced cucumber salad. This was nice to balance the spices.





Various phono cartridge output impedance

At your risk.


Measuring with a digital Escort LCR meter. The signal emited by the meter seems to be typicaly 1024Hz?


Ortofon OM: 890 Ohm


Metz turntable original cartridge; 660 Ohm


Shure Encore Me 75ED: 1.18 Kohm


Stanton 681 eee Calibration: Right channel 1.8 K ohm, Left channel 1.7 Kohm


Unknown Stanton found on a Technics 1200 MKII, possibly type 680: 1.68 Kohm





Cooking at 16 degrees Celsius

At your risk.


Leaving for example red lentils in (filtered?) water, protectively covered for 48 hours.


Then adding vigin olive oil, freshly ground pepper, fresh lemon.



 

A High Quality Battery Powered Phono reproducing system of less than 2W power consumption

At your risk.


1. A turntable such as Dual CS511 with its 12V DC popwered motor and only less than 1.5W power consumption.


2. A Pleiades 2 K117 JFET RIAA phono preamplifier. Typical idle current of the order of 50μA for the input stage, and 0.5A for the output stage. 12V or 24V battery powered.


3. The power amplifier (2 of them for stereo)  in class A too is a Pleiades 2N3053 single transistor amplifier with airgaped output transformer, battery operated at 24V, 14mA. Driving Celestion Ditton 150 loudspeakers in a small room.


So it seems rotating the turntable platter consumes the most energy!


Please visit previous posts for more details of each amplifier. There should always be a suitble fuse in series with any battery for fire hazard protection.


D series electron tubes with battery filament cathode can also be used for such amplifiers (higher power consumption but much less than indirct heated 6.3 volt electron tubes). Caution of potentialy lethal voltage even if they may be operated at 48V plate potential. Please visit previous posts for more details on Pleiades DL93, (DL94), DC90 amplifiers.











Ortofon

At your risk.


Revisiting Ortheus audio, distributors of ortofon in Hellas. they are very helpful. I bought the 100 year aniversarry Ortofon book, very interesting.


In fact if I undersatnd well the OM, concorde cartridges are neither moving coil nor moving magnet. They are VMS, variable magnetic shunt. A special case of moving iron. The ring? magnet and coils are inside the cartridge. The stylus cantilever is very low mass and its movement changes the magnetic flux in the magnetic circuit. Possibly something like the electric guitar string!


I guess this is why the Dual CS 501 so much imressed me. Also why the Stanton 680 moving iron cartridges inmpress me too.


There is something amazing to the delail and warmth of these.


So naturally I am thinking of perhaps using an Ortofon OM cartridge on a battery powered DUAL CS 511.
