I’ve had this put away at one time I used it, it is the old tube type some use to say that they were better but I don’t think so myself but if you like seeing tubes light up this is it, not asking a lot because it is old, I hooked it up to power supply and it came on, I cannot test it my antenna got hurt in storms we just had so good luck and enjoy &

Thank you

Please don’t think you can just hook this up without some cleaning done but yes when I stopped using it 30 years ago it worked fine and still today the tubes light up as you can see, thanks
