1977 Hitachi HA-330 Vintage Amplifier Restoration | Retro Repair Guy Episode 2

In this episode, I restore a vintage audio amplifier, the 1977 Hitachi HA-330 OCL type amp. For this vintage audio repair, I had to recap the whole unit and make a small modification required to upgrade the new larger capacitors and give this vintage amplifier a new life.
