Teac DA-P20 for parts

Audio Proz Inv #: 34625

Portable DAT unit with power supply for parts, playback has distortion. Parts Machine, Low Use, Unknown problem, complete intact.

A number of people have contacted us looking for the battery to these units. At this point, most used batteries left over in storage may be bad. Lead acid batteries, if kept under consistent charge, will go bad or have poor operating life. The power supplies are obviously special and retain the most value and demand. We do have the power supply for $60. For $80 we also have some of these complete machines, in good condition but in need of service (usually to repair either the head preamp or the servo circuit system -- both of these circuits are notorious for developing problems with bad capacitors). The repairs would probably cost about $200. These units are in good shape, but were abandoned to us by customers who simply did not want to go ahead with the repairs needed. But really, they are a bargain for a technically minded person who can put a little TLC into them. We repair the Panasonic SV3700, 3800 (which are the best), and some Sony DATs (R500, etc). The Fostex, Tascam DA30 MKII and Pioneers are serviceable too with parts available. No repairs can be done to Sony TCD8s or Panasonic SV255 as crucial parts are no longer available.

We are presently operating on an APPOINTMENT ONLY basis. Please call us first at (617) 926-8020 to schedule an appointment before you come into the shop for repairs, rentals, product recommendations, consultations, or anything other than minor purchases.

Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.
