Description

Editor-in-chief recommends

Tube amplifier OTL: The scheme is hopelessly simple. Elements that are easy to get. The system does not require tedious regulation. All art, not only to sound good, but also to present itself beautifully!

Practical workshop power supply: One thing is a practical, useful in every workshop regulated power supply. But the second thing, no less important, is the aesthetic, elegant look of the whole. Do you also enrich your studio with such a useful and nice instrument?

Renovation of the Largo receiver from the pre-war company Elektrit: Rarity for connoisseurs: a robust radio receiver, built eighty years ago in Vilnius, not only repaired, but also restored to a condition close to the original one.

Radio polygon. Generators from PLL, DDS synthesis: In an interesting way, the author introduces us to the world of modern ways of generating larger and smaller frequencies.
