This is probably a very collectable item, for well, antique Radio collectors or am amateurs. But I will test it to the best of my abilities, insure that all tubes and components function as designed. It was packed up over ten years ago, see pictures and has been in storage ever since.
Dim x 18 15. No point in having a door stop. I have the cover not shown in pictures, will update. This unit was operational, at the time, but I will fire it up soon enough unfortunately for me have no use of any tube related equipment as i've been off grid over ten years, by choice, so power consumption is not an option.
In fantastic condition. I do believe that may have an original manual, but will need to search for it, worst comes worst, probably it in PDF form.
Probably manufactured in the 40s or 50s as it does use octal type tubes. Shipping info: weight 27 lbs.
