Heathkit ®TM Weather Station Wind Cups P/N: 266-939

The Heathkit Models ID-1890, ID-4001, and ID-5001 Digital Weather Computers were the 'state of the art' in the 1970's. We had designed the weather sensors from scratch and the plastic injection mold for the wind cups was a complicated close and twist type of mold. The original mold has been retired and can no longer be used to re-create these original plastic parts.

We have contracted a well known plastic injection molding company to create replacement wind cups that, when assembled, will replace the original one piece set. In addition, we have selected a newer material that should last much longer than the PVC type of material that was originally used. This new material has glass fiber added to the plastic material that will increase its strength and a UV inhibitor that should reduce the aging caused by exposure to the sun. The biggest advantage is that, with this new wind cup design, any individual broken cup can now be replaced for much less cost than having to replace the entire wind cup assembly.

This is our first plastic Heathkit replacement part. We plan on building the molds for many other original parts. Your input is welcome as we decide what the next items might be.

We hope you enjoy the work that we have put into supporting the Heathkit ®™ Vintage line and look forward to expanding our offerings for other models.

IM-103 Rebuild Kit

This is a kit of parts typically needed to repair the Heathkit IM-103 AC Line Voltage Monitor. This kit of parts contains the typical parts necessary to rebuild your IM-103 and get it working accurately again. In the kit you will find replacement parts for: R1, R2, R4, D1, D2, D3, F1, and C1. These are typically the parts that fail over time with normal operation.

Resistors R1 and R2 have been upgraded to 5 Watt resistors from the original Heathkit design that called for only 2 Watt resistors. This additional margin should allow your IM-103 to now function over a longer period of time than did the original kit.

Heathkit AJ-1510A Display Replacement

The AJ-1510 and AJ-1510A are one of the first synthesized FM Stereo tuners to be introduced in the 1970's. Today, these units are not only nostalgic tuners from the golden audiophile era, but they still have very respectable performance. The biggest problem in keeping these operational is display failure. These units were designed before the advent of LED displays and utilized a 7-segment filament type display in a glass tube. Over time, the fragile filaments will break causing one or more segments to no longer light. These displays are almost impossible to find.

We have several of the AJ-1510 FM Tuners and to help keep them running, we have designed a replacement display using newer LED type displays. The modification consists of two boards that replace the existing driver board and displays.

Each kit contains all of the parts that you need to convert your AJ-1510 or AJ-1510A FM Stereo Tuner from the original displays over to modern LED displays. It is also possible to reverse the modifications and go back to the original displays, should you ever decide to do so. It takes about an hour to build the new kit and replace the old display board with the new one.

IG-18 THD AND METER Mods

There have been lots of articles regarding the improvement of the Heathkit IG-18, but none of them have ever offered a complete kit to make these modifications for the DIY'er. We are now offering a complete kit to upgrade the Heathkit IG-18 based on the many articles that cover the IG-18. This same upgrade can be performed on the IG-5218, SG-18, and the SG-5218. These upgrades involve value changes of existing components. There are no modifications to the PC board or added holes. You can at any time, restore the unit back to it's original condition. The added meter buffer board can simply be removed and put back into it's original design. There are NO 'Hacks'!

We have discovered that a very few of the last IG-5218's utilized a meter that was manufactured in Japan. This meter, while having the same electrical specifications as the earlier meters, has a smaller physical spacing between the meter terminals. For this reason, we have paid the additional expense to have new PC boards manufactured that will fit both styles of meters. We will constantly strive to improve our products even if it means throwing away perfectly good PC boards.

This kit is available in two formats; one complete kit including the parts that need to be changed in the original IG-18, and a supplemental 'meter buffer' only kit for those that have already made the basic changes to the Heathkit IG-18. It comes with a complete step-by-step instruction manual for making the changes.

Heathkit SB-6XX High Voltage Repair Kit

This is a kit of parts typically needed to repair the Heathkit models SB-610, SB-614 and SB-620 Monitor scopes.

This kit of parts contains the typical parts necessary to rebuild your scope's High Voltage and get the brightness and focus working again. The original resistors were of the carbon composition type and these are known for drifting 'high' in value over time. In the kit you will find replacement parts for the two 3500 Volt diodes, the three 1600 Volt high voltage filter capacitors, plus various resistors to replace those in the high voltage circuit around the focus, brightness, and accelerator circuits. These are typically the parts that fail over time with normal operation.

The high voltage capacitors are Cornell Dubilier and the high voltage diodes are Vishay. All of the replacement resistors are quality film type that will not drift over time as did the originals. The kit includes 'easy to follow' instructions for replacing the necessary parts in your particular scope.

HDA-1250-X Coil Kit

The Model HD-1250 is one of the most powerful 'Dip Meters' you can find. Rather than using a vacuum tube, it uses a Dual-Gate MOS FET paraphase amplifier and hot-carrier diodes for more sensitivity and a better 'dip'. It also uses a 'Q' multiplier for greater detector sensitivity. The HD-1250 comse with 7 different plug-in coils to cover 7 bands from 1.6 to 250 MHz.

Unfortunately, when one of the band coils goes missing, you can no longer use the dip meter on that band. We have created replacement coil kits that allow you to build any of the missing coils for your HD-1250. These coils look and feel just like the originals and operate with the same response.

To make assembly easier, we have already wound the coils that have the larger number of turns of wire. You only need to hand wrap the higher frequency coils that have a smaller number of turns (16 or less). It is much easier to make a coil with over 200 turns on a coil winding machine, rather than try to wrap it by hand.

The tools that you will need are: a soldering iron, solder, wire cutters, a knife, a small drill or pin-vice (1/6" or less), scissors, and some quick drying glue. We prefer the white Gorilla Glue because it matches the color of the coil form.
