Vector Research amplifier c. 1980 failed to supply feed to left speaker about a month ago, a now no feed to either speaker. Do replacement parts exist for an amplifier this old? Are there technicians available who can identify the source of output failure?
Vector Research VR-5000 AM-FM Stereo Receiver (Japanese mfr). Powers pair of OHM L bookshelf speakers. Have TEAC CD player attached, connect via Dell laptop to access YouTube streaming music.
Would prefer technician-repair in Mountain Southwest region (US)
