HI! Welcome to my AKAI REEL TO REEL Photo Pages...

>>>>>> Suggestions and Comments are Welcome.. <<<<<<

I repair the later Akai's ( also Sansui and Pioneer Reel Machines ).

In the course of repairing and restoring many later Akai Reel to Reel Machines, I noticed a similarity of three types of failures that afflicted many of the later Akai's. To answer the need for a relatively inexpensive cure and fix, I have obtained the parts needed to make an improvement in the Servo-Control Function. I have never actually encountered an Akai Capstan Servo-Motor that had actually failed, but among the later Servo-controlled sets I have seen many where the electronic circuitry powering it has failed.

So, several years back, I prepared a general Akai Servi-Fix Kit which is applicable to most of the later GX-2xx and GX-6xx Series Servo Motor Reel to Reel Decks ( except not applicable to the GX-280D, GX-280D-ss, GX-297D-ss; or GX-650D, or the various iterations of GX-400D units, or PRO-1000 ). Installing this kit, which does require much disassembly, and about two hours work, if you can solder, and have a DMM or VTVM, you can repair your later Akai Servo Motor problems - those that crop up after twenty plus years. Symptoms seen: Either the Capstan Servo Motor starts to behave erratically, with speed variations, or it has gone to full speed, or it has stopped completely. In sets that have several internal fuses, it may also be necessary to replace blown fuses, these may be either GMA or AGC type, depending on the set version and type of failure, so the fuses have not been included, but a Spare Fuse Kit is also available.

The Servo-Fix Repair Kit comes with four pages of descriptive text and includes better-than-the-original repair parts, which repairs many of the Servo Motor problems seen in these later Akai Reel to Reel tape decks in the "GX" series. Due to the use of a special-order high current, higher power part, the kit can also be used pre-emptively to prevent failures that would eventually happen in these decks. So it repairs and also prevents future occurrences. This kit is specifically for the GX "Glass Head" sets using either the SCM-2-24KJ Servo Motor, which would include ( but not be limited to ) models: GX-230D, GX-265D, GX-266D, GX-267D, GX-270D, GX-270D-ss, GX-630D, GX-630DB, or GX-630D-ss; as well as those higher-end sets which used the SCM-200 or SCM-200B Servo Motor, models: GX-255, GX-266II, GX-620, GX-625, GX-635D, GX-636, GX-646, and GX-747 sets.

The cost of the Servo-Fix Repair Kit is $35.usd including shipping in the continental US/Canada. Add $5. for International shipping. For orders paid for by Paypal... add $1. extra to cover fees. Use email addresses: or to make payments.
The Akai GX-Series Spare Fuse Kit is also available. Specify either the GMA 5x20mm Metric fuses or AGC type fuses ( depending on AKAI Model ). Fuse Sets contain ten fuses, two of each of the most likely values to be found inside later Akai's. The cost is $10.usd including shipping in the continental US/Canada if ordered with the Servo-Fix Kit.

In addition, during the 4nd Quarter of 2003, the Akai SYSCON Rebuild Kits are slowly coming out. These are a more extensive kits which are quite machine specific and are designed to reduce failures both the SYSCON and PREAMP circuit boards of a specific Akai model Reel to Reel machine. It contains many more parts, such as the Gold Plated Contact 4 Pole Power Relays, bridge rectifiers, transistors, and other replacement parts that have become lessor known failure modes causing intermittant and ocassional problems after sets have become 25 or more years of age. Requiring much disassembly and many hours of work, it is oriented towards the skilled audio technician.

Even as early as the late 1970's Akai realized that a number of parts were failing inside their sets at higher than expected rates. And while these failures were still rare during the 1980's, these failures are now becoming increasingly common... 20 to 25 years later. Parts on both the Syscon Boards and the Preamp Boards are failing at alarmingly high rates. These SYSCON Rebuild Kits are designed to take pre-emptive action by replacing many more parts than just the Servo-Fix kit ( it does also contain my Servo-Fix Kit ).

Obviously sets like the GX-266D, GX-267D and GX-266II which contain only a few of the difficult to find and costly Power Relays would have a less expensive price than the GX-400D, which requires 8 of those Power Relays, so each kit here is more specific and tailored to each individual sets' needs. Some sets may not have Syscon Rebuild Kits, such as the early X series, or the GX-365D, whose 13 Proprietary Power Relays would simply make their replacement cost prohibitive, at more than double the typical value of the GX-365D in todays market.
