BUYER BEWARE - Andromeda III, 7000II & 9500

BUYER BEWARE!

The products listed below are suffering from age and use. Some are simply beyond economical repair. Take this advice into account when negociating to purchase them. Do not buy a basket case and assume you can have me restore it to working condition. Forewarned is forearmed!

 

Andromeda III/Phase III speaker system

1. The subwoofer drivers sag from being mounted upside down plus the additional weight of the cardboard rings used to add mass. This causes a gradual decline in output and increase in distortion.

2. The 8" lower mids had rope calk pressed into the dust cap to add mass. The calk was covered by a felt disc which hides the damage. Over time the calk causes the cone to disintegrate around the voice coil. Symptoms are rattling or high distortion. Carefully remove the felt disc and inspect the cone.

3. The dispersion cones on the 1" tweeters get cracked and damaged. To my knowledge these were custom made and there is no off the shelf replacement.

4. Crossovers on speakers above serial #1736 are mounted on the PC board. The 8 "coil gets very hot under high power and can melt. See AIII Service Bulletin.

The 12" sub woofer drivers and 8" lower mids can be reconed. Inspect them carefully and determine if re-coning is necessary. Check your local yellow pages under speaker repair or your local professional music store. Re-coning service is not provided by Phasetek.

7000 II Cassette Deck

1. The reel motor lever full assy. (idler pulley) gets very sticky with age and lack of use. The worst thing an owner can do is let the deck sit unused for years. Until a few years ago I was able to get the pulley working by completely disassembling it and oiling it with teflon oil. Recently this remedy has failed to get them working. New pulleys are not availble.

Test the transport by playing a cassette and watch for spilling tape. If so, the deck is beyond repair. This failure is not due to a worn capstan belt.

2. The Microscan PCB is a double sided board with dozens of feed-throughs connecting the front and back side of the board. The solder has deteriorated to the point where numerous feed-throughs are failing. Troubleshooting and repairing them is very time consuming. Further problems can develop after repair.

Test the microscan circuit. If it's not working the deck is probably beyond repair.

There are NO NEW MECHANICAL PARTS AVAILABLE for the 7000II except for the belts. See Belt Bulletin.

9500 CD Player

The 9500 was built as the DA-01 by Kyocera. Remember, this is a first generation CD player with no oversampling and a complicated servo circuit not up to modern standards.

1. The laser pickup gets weaker with age. This may cause intermittent skipping, especially with CDR discs. It can be adjusted with the use of a laser watt meter and the service manual. Do not attempt to adjust it by without the proper equipment and experience.

The only thing the user can do for the laser is clean the lens with a cotton swab dipped in isopropyl alcohol.

2. Minor skipping may be caused by servo misalignment. Alignment is a time consuming process with NO GUARANTEE OF SUCCESS.

If the disc fails to initialize or skips severely, the player is beyond repair.

There are NO NEW MECHANICAL PARTS AVAILABLE for the 9500 except for the sled motor belt. See Belt Bulletin.
