How often do you have to service your Studer or Otari deck ? Home not pro environment.

the machine is the inexpensive bit........

Two things - hunting for master tape dubs and making compilations off records and even maybe some cds.

Restoring Revox A77's is expensive. I sent mine to the national service center in Nashville years ago, and the restoration cost me more than the A77. It's like servicing an old BMW; there comes a time when it no longer makes economic sense.

Buying from a reputable source can also be difficult or impossible.
That's what I thought, if I use the deck for, say, thousand hours a year, I would need to have it looked over every five years or so.
But, how long do the reproduction heads last, assuming best tape and head cleaning every ten hours ? I would also treat the head with LAST tape head preservative. I do it now with Nakamichi before playing each cassette and as my tech said there was only negligible wear. The deck has thousands of hours put on it by me and I didn't buy it new, though it was used very little before.

bdp24, audiophile endeavor makes no economic sense whatsoever. People wear out $10k cartridges and $500 NOS tubes.
