About
Innovative tube amplifier technology
The Tube Sound Laboratory has developed and promotes a new technology, not yet used by any of the tube amplifier manufacturers in the world, for manufacturing high-quality and powerful HI-FI and HI-END tube amplifiers. The invention (patent No. 2693287 dated 07/02/2019) and technology is based on the idea of supplying voltage to the output stage not from a power transformer, but directly from a 220-volt supply network through a rectifier or voltage multiplier.
This technically implemented solution speeds up the charging of power filter capacitors tenfold, and together with the use of output tubes in the grid current mode, it can dramatically improve all the parameters of household HI-FI tube amplifiers and top-level powerful guitar amplifiers. The problem of galvanic isolation is reliably solved.
Compared to existing amplifiers, the results are as follows:
Production costs are reduced
Power is increased
Dynamic characteristics are increased
Distortion and noise are reduced, reliability is increased

Benefits of technology
Greater gain in all parameters
The presented technology gives the greater gain in all parameters, the higher the power of the product, since the more powerful and therefore larger, heavier and more expensive supply transformer is excluded from the circuit and design. This technology is especially relevant for portable powerful sound amplifying equipment, for example guitar amplifiers, due to a significant reduction in weight and dimensions with better sound quality, more power output and better dynamics.
The proposed technology does not involve the use of scarce or expensive parts and components. As a result, the manufactured product is high quality, simple, affordable and highly competitive from a market point of view.
To everyone who wants to produce record-breakingly efficient tube amplifiers and is interested in the technology, Tube Sound Laboratory recommends the article “ABOUT THE QUALITY OF SOUND AMPLIFICATION” and is especially interested in contacts with manufacturers of HI-FI amplifiers.
