<p>Creating user page for new user.</p> <p><b>New page</b></p><div>I&#039;m an electronics engineer. I design and manufacture audio amplifiers using transistors and vacuum tubes. I spent twelve years repairing Soviet-made audio equipment in my professional career. My total experience in electronics spans over 50 years. I&#039;ve repaired virtually every amplifier, tape recorder, and vinyl player. I&#039;m particularly skilled in upgrading highly complex reel-to-reel tape recorders. I also design and manufacture acoustic systems.</div>
