Here is for sale, a Dentron GLT-1000 from my research looks to be from the 80's and was designed to mate with the Dentron 1KW amplifier and looks to be hard to find because a small number were manufactured.? I think it has an issue, i tried using it as a regular tuner with my radio, but it doesn't seem to have any operation in tuning. I would imagine this could be a simple fix, probably the input being disconnected? Let me describe what it is doing. My Vertical at the moment is 10:1 SWR on 20 meters because i have to trim the spokes. So when i put this tuner inline, it seems to have some sort of effect and my antenna is showing 4:1 SWR and i have receive, but the inductor or load or tune knobs are making no changes in SWR, and i can't tune the antenna, so of course i would guess that the inductor and ALL the capacitors did not ALL go bad at the same time, it must be a main failure point probably from running more than 1kw into it. The unit is solid, and i will clean it up before shipping. The coax 1 and 2 selector is working and receives through this tuner so something is connected somewhere. But i am not taking it apart. It is a bit heavy so i will have to calculate shipping charges to your zip code via USPS. email me because i get emails right away, but i do not check through the responses on this listing. I work for a living but i will respond to your email. Email is good on QRZ, i am also on facebook search "HamRadioConcepts". The best offer ready to pay through PayPal gets it. But don't be silly on the offers, i know it can be fixed, and if it does not sell in a few days i will be taking it apart and fixing the issue and relisting. Thanks for looking.
