Important Announcement as of 04/16/2026

The Test Probes used in the production of this item - Genuine Philmore 912J/913J have been restocked. I have been advised that I am the largest consumer of this item in the world, I have obtained substantial inventory and am no longer using Chinese Probes in the production of this item as was announced on 02/02/2026

This listing is for the

- KK4HXJ -

Deluxe Heathkit IT-5283
assembled test probe set

The  Heathkit IT-5283 uses a switchable test probe like many Signal Tracers of the day but due to lack of appropriate probe bodies retail quality "switchable" probes are not available

The KK4HXJ solution is a "Siamese" test probe, which has seperate probes for Audio and RF functions as well as a shared ground lead

these devices are especially subject to RF inteference and shielding of test leads is imperitive, this design uses a BNC connector to help maintain shielding and an adapter to mate to the meters Banana plugs - this makes a much more durable probe than mating RG174 to Banana Plugs directly and makes it easier to maintain the ever important shielding!

This auction is for a completely assembled set of test probes for the Heathkit IT-5283 and an included Banana plug to BNC adapter

This probe is similar to many of the Siamese style replacement probes I have produced for years

The unit is presented in a Labeled, Retail Quality, Reusable, 4 Mil Poly Ziplock Bag and is wrapped with a Reusable Velcro Strip to keep the leads organized and ready.

This dual probe setup, serves as a substitute for the mostly missing or incomplete original test probe which used a switch at the tip of the probe to switch the Resistor in/out of the circuit.

This Siamese or Dual-Probe arrangement involves using one probe for RF tracing (with the cap and diode installed) and the other probe for Audio tracing

The probes are built from my kit which is composed of the following items (many of which are hard to source economically):

1 Pair of Genuine Philmore Test Probes - 1 Red/1 Black

1 BNC connector with heat shrink Sleeve

1 .001uF Capacitor and 1N34A Diode

1 Alligator Clip & Heat Shrink Tubing

2 Laminated Self Adhesive Probe Labels and Clear Heat Shrink Tubing to cover the probe labels, resulting in a professional and durable setup (see photos)

2 36" lengths of RG174 Coaxial Wire (used for DC & AC/Ohms test Leads) (Very Flexible - makes a great test lead) 

1 36" Length of 18 Gauge Rubber Test Lead Wire (Very Flexible - High Quality) for the Ground Lead

The original instructions specify shielded cable for the leads, the original supplied wire was a coaxial microphone style wire, many people use either standard (unshielded) test probe wire for the leads or a shielded coaxial cable, I use shielded black RG174 for the 2 leads and Black test probe wire for the ground.

I have shipped these probes and kits to several dozen countries and have received nothing but praise for bot the kits and probes, I think you too will be pleased with this simple and durable set to get that old meter back in service!
