Part of major component SB-22/PT: Line Pack TA-222/PT SM-D-84429 NSN: 5805-00-503-3337A Note of Caution: When buying the spare SB-22/PT line jack accessory kits MX-2915/PT or MX-230A/PT with three line jacks (telephone circuits), be sure that all line jacks in them are new, unused. Or if there are used ones in there, ask the seller if they have been tested. Here's why. My experience with this equipment of 12 years on and off as a Signal Battalion Officer for Mech Infantry, Artillery and Armor units. These spare accessory kits with new line jacks were used to replace defective linejacks on the SB-22/PT switchboards. We, or my repairmen, would exchange bad for new/good linejacks and put defective ones back in the Kits to later turn-in to higher maintenance. 99% of the time, these defective units remained in the accessory Kits; we just ordered more new Kits. In time these Kits with defective units were just turned in as excess, and eventually consolidated and ended up in government auctions.

Typical images of used SB-22/PT Field Military Switchboards
If you are missing a headset, I currently have new-mint condition Microphone H-182/PT Headsets with Tech Manuals and an extra new ear cushion available.
Below are images of typical areas or components one should be concerned with when buying switchboards:
Front cover carrying strap. side Latches and clips, and the recessed hinged latch are typically areas of concern.
Currently I have in my inventory 30 switchboards. About 25 are complete switchboards without missing component or broken part issues. The remaining ones I use for repair and for replacement parts. As you can determine, I have the resources to fix and replace before I sell -- I can support with replacement parts after the sale. My first three years of my 20-year career, I repaired field telephones and SB-86/P and SB-22/PT switchboards.
