The X-1000R dbx was a high quality, three motor, quarter-track stereo tape deck. Several variants were produced with the following suffixes: R (bi-directional record/playback) dbx (DBX-I noise reduction system)
The R model featured six heads, full auto reverse on both record and playback while the dbx models were equipped with a professional level DBX-I noise reduction system. Braking was electrically-assisted, and the tape was handled by a dual capstan drive. A three position tape-type selector gave the user optimum bias and equalization for normal, LH or EE tape. An electronic digital tape counter gave ‘real-time’ positioning.
Other features included: Pitch Control, Tape Lifter, Dupli-Sync, Auto Spacer, Auto Timer
The 1000 was available in matt black or silver finish, in a wooden case or rack-mountable.
Fairly common is capstan motor failure on the X-1000, X-10, X-700 and many other models. Good preventative maintenance is to turn the machine off when you’re not using it as the motor continues to run while powered up. If you are in need of replacement, there are other motors that can be workable. The original is rated at 7w however the BR20 capstan motor is usable, rated at 12w. Apparently the much rarer X-1000M half track machine used an 11w motor.
If you find a similar motor then keep the original servo board after doing a check over (worth testing the board first. The most common component that fails is the larger heat sinked transistor, 2DD235 or 2SD880.
Before you check the transistors on the board…
- Apply DC voltage between 3 and 24 to the 7W motor across the wires in the grey outer, with one or other disconnected from the control board, to see if the motor spins.
2. If the motor spins, power up the deck and push up the tension arms. Check voltage across the pads that the motor connects to is in range and varies with the speed switch.
3. If no voltage is found, check the supplies to the board. There are two DC supplies, pins detailed in the schematic. If the supplies are good, troubleshoot the control board. If the supplies are bad, troubleshoot the power supplies on the main vertical PCB (left side of the board)
