Laser Photonics L5830 TDL Controller For sale- a Laser Photonics L5830 TDL Controller as pictured. It powers up but is unresponsive to the controls and the display does not come on. Accordingly it is sold for parts or repair only, and no returns will be accepted. All items are sold as is with no warranty offered unless one is specifically stated. Any testing done will be explicitly stated in the listing and any accessory items will also be mentioned or pictured. If it isn’t pictured or mentioned you can assume it is not part of the sale. Please check out my other listings for more interesting lab, test and optical equipment. Check back often! Please add a $38.99 flat rate for shipping anywhere in the continental US (which does NOT include Alaska, Hawaii, Puerto Rico, Guam or APO/FPO addresses). I will ship via the carrier and level of service of my choice unless we specifically decide on a favored carrier option. I will, at my option, ship worldwide via USPS for the actual cost as determined by USPS.com. If the item being sold here requires a standard modular computer style AC cord I no longer ship those automatically on the theory that everyone has a box full of them already. If you need one all you have to do is ask and it will be included in the sale. IF you do NOT ask for one until after the item ships it is no longer part of the sale and I will not ship one separately.
