Tube Sound Laboratory

Development of innovative tube amplifier circuits

About

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:

Weight and dimensions are reduced by 30%

Production costs are reduced by 20%-30%

Power is increased by 50%

Dynamic characteristics are increased by 3-5 times

Distortion is reduced, noise is reduced, reliability is increased

This new breakthrough technology has been created and researched for 5 years (since the first variants on this topic appeared), the technology has gone through all the stages from R & D (experimental design development) to the manufacture of experimental and exhibition specimens of various power and purpose, which have proven themselves from the best side, giving out the quality and power of the amplified sound is higher than that of the models available on the world market (even very expensive and elite ones). To date, the presented technology is completely ready for implementation in industrial production and does not require any modifications or additional research.

Benefits of technology

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.

In conclusion, it should be noted that the proposed technology, with a large number of the above positive qualities, in practice, when used for the production of amplifying devices, does not involve the use of any scarce or expensive parts and components of the structure, as a result, the manufactured product is of high quality, but at the same time simple and cheap, and therefore highly competitive from a market point of view.

To everyone who wants to produce record-breakingly efficient tube amplifiers and is interested in our technology, I recommend that you read my article “ABOUT THE QUALITY OF SOUND AMPLIFICATION” , I will answer your questions, I am especially interested in contacts with manufacturers of HI-FI amplifiers.
