Item Description

CLEAN LAB SURPLUS — Genuine Tektronix Wave Inspector Inner Jog Control Knob

Up for sale is a factory-original Tektronix Wave Inspector Jog Knob, part number series 366-0865-XX. If your premium Tektronix platform has spent years in a heavy-use engineering lab, chances are the primary navigation dials have either developed sloppy play, accumulated permanent bench grime, or vanished entirely. This OEM replacement drop-in restores original tactile precision to your front panel console.

This specific inner dial handles panning, fine step-by-step record adjustments, and detail scrolling across large sample memory deep-dive captures. It is a direct factory replacement compatible with Tektronix's premier bench architectures, including the 4000-series platforms (MSO/DPO/MDO and their "B" variants) right up through the high-performance MSO5000 and MSO5000B series mainframes.

Key Mechanical & Cosmetic Highlights:

  • Crisp Internal Splines: The inner collar mounting channel is clean and free of stripping or wallowed edges. It slips firmly over the rotary encoder post with exact factory resistance—no slipping or sloppy play during high-speed panning.

  • Ergonomic Finger Dimple: The integrated front-face indentation is completely round, providing a smooth spin radius for fine, single-finger waveform adjustments.

  • No Material Degradation: Reclaimed from a clean, low-hour laboratory unit. The outer grip perimeter shows zero signs of the typical chemical stickiness or breakdown common with high-mileage controls exposed to industrial solvents.

Condition & The nyctesttech Advantage:

This knob has been lightly cleaned and inspected on an active bench enclosure to ensure mechanical mounting integrity. Avoid generic 3D prints or cheap silicone caps that ruin the weight distribution and exact clearance required for the dual-concentric Wave Inspector stack. Buying a genuine factory original protects your instrument's performance and long-term resale value.

Store Policy & Logistics

  • Secure Bench Packing: Small front-panel dials are highly vulnerable to post-office sorting machinery crush damage. At nyctesttech, this original component will be placed in a protective zip-top parts bag, enclosed inside heavy-gauge bubble casing, and shipped inside a rigid box to guarantee it arrives at your workspace ready for an instant push-fit installation.

  • Shipping Logistics: Promptly dispatched within 1 business day via tracked shipping.

  • Guaranteed Integrity: The detailed high-resolution listing photographs display the exact inner collar formatting and cosmetic face condition of the genuine Tektronix navigation dial you will receive.

MEET YOUR SELLER:
I offer a wide selection of Genuine Tech and Electronics Items from some of the leading manufacturers, the majority of which are sourced directly from Tektronix. Every item presented for sale is carefully inspected and examined before listing. Where appropriate, more information is provided, with the information I think you would want to know. With very few exceptions, "Used" items are pulled from working environments (manufacturing areas, engineering, marketing or sales, and occasionally customer upgrades). "New" and "New -Other" items are usually unsold overstock items. My high positive feedback rating (while selling used electronics) is a testament to the work I put in to acquire, verify and sell quality items. Buy with the utmost confidence.

TESTING:
New items are rarely ever tested. Used items are tested to the extent I have the capability. Given the wide variety of items sold, it would be impossible to test everything. I rely on my sourcing methods and provenance to only sell good working units, and any item not working is listed as such. Many items in store are decades old, and will have imperfections. They may also be subject to the hazards of transportation. Electronics also fail, and are sometimes intermittent. In the unlikely event an item differs materially from what is listed I will gladly work with you to resolve any issues. Unless stated, items are never calibrated before sale.

DOMESTIC SHIPPING:
All items will be appropriately packaged and shipped to you using the fastest possible method given what you have paid for shipping. Free shipping items are also shipped with the fastest reasonable method. Most items are shipped the same day from the west coast, ensuring items get to you even faster.

INTERNATIONAL SHIPPING:
I have had the pleasure of selling to customers in all parts of the world. Thank you for your trust over the years. Most items are available to purchase through the eBay Global Shipping Program. I am also able to ship items to most countries directly, using your account. This includes high value items that require export documentation. I do charge for this as it is very time consuming. Please contact me directly before buying if you wish to have items shipped directly to you.

PAYMENTS:
Standard payment methods are accepted. For high value purchases, I can also accept wires. Buyer pays all wire fees, including any charged by my bank. Please contact me directly before to discuss these options.  

RETURNS: 
In the unfortunate event that you believe the items needs to be returned, please be sure to contact me first. Because of the complexity of international transactions, international returns are not accepted. Please ask all questions before purchasing. Refunds for returned items are promptly processed once item is confirmed to be as it was shipped (unopened/unaltered/quantity).
