CV of Georgios Tsakiris

The pleasure of meeting yesterday Alexandros and his unique kindness is an inspiration on making a better CV. Or at least one that I can enjoy writing.


Born in 1972 in Athens.


1972-1982 (0 to 10 years old)

Piano lessons at National Conservatory

Starting teaching myself the ability to recognize musical notes by ear. It is something very useful that can help understanding how notes are combined together even when passing through any place where music is being played. I still seek to improve it everyday as any newly discovered interesting song is always a challenge. Recognizing the notes in the bass is the most difficult but once this can be mastered the door to understanding opens as the word bass can be traced in the Hellenic word "Βασις" meaning foundation [1]. Below is the song Bones by Telenova which reveals itself beginning with the bass only:


Of course lack of this ability is no obstacle in enjoying or even composing great music.

First attempts in constructing electronic circuits, radio receiver, transmitter, amplifier on the pedagogic games Polycyclomatic 1002 or 501, discovered on a schoolmate's party. The electric and mechanical connection of the electronic components is done with springs while following the assembly instruction schematic. At the time I did not know what an amplifier is so when noting was heard on the speaker except a click sound I was puzzled to what was done wrongly.. Disappointment have itself to joy when a radio receiver was connected to it and music appeared clearly heard in the room. The simplicity and nice sound of these experiments are still an inspiration on designing or improving the simplest possibly electronic circuits.


1982-1992 (10 to 20 years old)

co DJing at school class parties, usually at Intercontinental Hotel ballroom
It's the 80s and we would play with schoolmate Yiannis Tieris vinyl records on rented Technics SL1200 MK2 turntables beautiful songs such as:



Small range FM radio station after building the legendary HF65 JostyKit. It is around 1985 and it is a joy broadcasting in city of New Smyrna songs like:



Making up a piano, electric bass, drums band at school's basement studio. This is the only instrumental we tried to play, there is a recording on cassette, here is the original:


Sorbonne C1 literature - University of Paris - Sorbonne French Language Diploma

Finished High School Lycee Leonin Franco-Hellenique - New Smyrna - Athens 

Failed panhellenic examinations for admission to a Hellenic university

With the help of family business Homer "Ομηρος" schools of English attending 1 year foundation course for university preparation at Coventry Technical College - UK. Distinction marks in Mathematics and Physics allowed entrance to University Of Warwick - UK.

University of Cambridge Proficiency in English diploma


1992-2002 (20 to 30 years old)

Final year project for B. Eng. degree: Design and Investigation of a Triode Single Ended Audio Frequency Amplifier with No Negative Feedback

Bachelor of Engineering in Engineering Electronics class C - The University of Warwick - England

Worked for a few months at Audio Note UK. Participated in the assembly of high end electronic valve (electron tube) amplifier kits for music reproduction.
 
Withdrew for Master's of Philosophy - Napier University - Edinburgh 
Area of research is on comparison between electron tube and transistor class A audio amplifiers for music reproduction 


 
2012-2022 (40 to 50 years old)

Having the pleasure to meeting again and interviewing legendary Hellenic songwritter Mimis Plessas in his 90s, on how he crafted some of his songs. The series is called Sectrets of Music (Μυστικά της Μουσικής). Here is the 1st episode recorded in binaural (3D recording) using the Pleiades binaural microphone (in ear headphones converted to housing a small microphone capsule for each ear). It is to be listened with headphones:



First sucess in making high end batterry powered audio power amplifiers operating in class A1 (electrons flowing all the time) with only one active device per channel (transistor or electron tube). The Pleiades 2N3053 currently the near field monitoring speaker power amplifier in Pleiades studio lab.


2022-

First sucess in making a high end battery powered DL series electron tube audio power amplifier with only one electron tube per channel, no other active or passive device (no capacitors, resistors) except an input and an output transformer and 3 battery power supplies. It is found that such high end amplifier was patented by Arnold 100 years ago. 

Current unfinished projects:

Designing and producing prototype of:

Pleiades EF183 or EL84 single ended class A1 audio power amplifier with no negative feedback with an input transformer instead of an extra electron tube

Pleiades DL94 batterry powered class A1 audio power amplifier with no negative feedback and an input transformer instead of an extra electron tube

Pleiades DK series battery powered electron tube microphone booster preamplifier

Continuing The Melody Book

Continuing the book A Letter to Clive Davies

Recording outdoors vocals or other instruments in order to have almost no reverberation at low frequecies
