Vacuum Tubes

We have built a lot of audio equipment with vacuum tubes and serviced a few classic mixer consoles and professional power amplifiers with tube technology. In some respects, semiconductors have not been able to fully replace the sound quality delivered be well designed and built vacuum tube analog equipment.
