Vintage Mcintosh tuner

MR78 designer Richard Modaferri offers his update/optimization of the tuner through Audio Classics. He incorporates everything he has learned about tuner design since the tuner was introduced into his update, improving both the 78's RF performance and it's audio quality. He also installs new gold plated jacks in place of the original nickel-plated ones, tests the tuner and provides a written report of your 78's performance results, including charts and specs.

 Richard also modifies other McIntosh tuners. He did a mod on my MR74 last year, and it now sounds identical to my MR78.

  I have bought used McIntosh equipment from both mcintoshaudio and audioclassics. Both are outstanding retailers and offer great repair service on McIntosh equipment.
