“True Life Audio’s design philosophy is the same since day one of the company’s existence and will remain unaltered for the future. In a phrase. We aim for excellence in everything we do.”
T.L.A SSA-350 MONO BLOCK
SSA-350 Mono block amplifier circuitry is a hybrid design, designed to deliver exceptional sound to difficult loads. Using both tube and solid state circuits combines virtues of both technologies to achieve the end result.
Tube rectification (GZ32 NOS) and Tube single ended input stage (6J5 NOS) driving an ultra linear solid state stage and solid state current amplifier.
2 separate Linear Power supplies are used to supply the required voltages.
First power supply is using a custom designed EI, low loss lamination transformer to deliver voltages required by both Rectifier and Signal tubes. A specifically designed choke using TLA’s technique is filtering the High Voltage for the tube front stage.
Ultra linear solid state circuitry takes over further amplification of the signal and delivers the signal to the current amplifier circuit that delivers the power to the load. Only bipolar transistors are used in the circuit. Semiconductors as well as resistors and capacitors are closely matched.
High quality copper, film capacitors in the signal path.
A Mosfet protection circuit is used to connect the load to the amplifier. After power up the protection circuit will wait aprx 13 sec before connecting the amp to the speaker, giving time to the tube heaters to warm up.
DC fault protection and high temp protection.
High quality PCBs. All boards are hand assembled. All parts of the amplifier are hand wired.
Highest quality components are used throughout the circuit. Each component is handpicked, tested and matched to serve the design.
NOS tubes are used.
Heat Sink is machined from Solid Aluminum and is an essential part of the vibration damping mechanism.
SSA-350 is designed keeping in mind that for a lot of speakers the actual impedance for some frequencies is well below their ‘nominal’ impedance.

About T.L.A.
T.L.A. (True Life Audio) was founded by Velissarios Georgiadis back in 1995, but its real origin goes back much further than this. It was back in 1957 when Velissarios' father Aristomenis, a transformer technician, started his own company, with the aim to make transformers under order for telecommunications, broadcast, medical, military and industrial implementations. It was just after 1980 when Velissarios, who was already experienced in transformer building having being taught all his father's know-how, he started to apply the additional knowledge which he gained from his university degree on Chemistry and Electronics as to develop transformers that would excel in audio applications of reference standard.
Velissarios developed, built and tested over, countless amplifiers before he transferred all this experience in T.L.A products on the year 1995. The name True Life Audio was chosen to underline the target market of T.L.A. The search for True Life sound, where the listener would experience music at home as never before, In a True Life manner!
In the year 2005, young Aristomenis Georgiadis the second (son of Velissarios, named after his grandfather), finished his studies in Electrical Engineering and having received in the meantime all his grandfather's and father's experience in making audio transformers and amplification circuits that would excel in performance, joined the company as to assist in further improvements and the achievement of new levels for realistic sound.
