Why repair vintage equipment when I can buy new?

Because the vintage gear you already own is almost certainly better than any new gear you can afford!

Nothing you can buy for sensible money now is built like old hi-fi equipment, or made in Japan. I regularly see equipment that is 40+ years old and has come in for its first repair. Do you think your BOSE or Sonos ‘thingo’ will be working in 40 years time..?!
