VU-метр ИЛТ4-30М + BA6800AS — новая жизнь ретро индикатора

In this video, I'll show you how to revive the ILT4-30M level meter using the BA6800AS chip. You'll see the step-by-step process of integrating the BA6800AS chip with the ILT4-30M. I'll share information about how I solved the problem of parasitic segment glow and why this phenomenon occurs. Learn how to restore and upgrade a VU meter for various audio devices, including tape recorders and computers. You'll also see a homemade enclosure made on a 3D printer. This video will be useful for anyone interested in repairing and creating electronic devices themselves.
