While browsing the net I found the manual for another one, "new" one QT-90,

strange enough, they made two different radios with the same model number

Interesting find Metad, I can't believe I recently passed on the original QT-90 at pawn broker close to home.

If wewe talking about the origional qt 90 there are 2 versions...one with 5 band eq and one with out...I had the one without the 5 band eq...loaded with features but it was nothing special...I need to dig out one of my pana rxc 52 havn't heard it for years...

I believe you meant QT-89, wich is virtually the same as QT-90, but without equalizer.

Ahh yess that's the one my friend.. I know on mine i changed the speakers...I put some out of an egg in there...and she did sound nice after that...Wasn't the dt707...it was the one with the led's on the front...forgive me my memory is failing me,,,

ive just got the qt89 for 6 pounds-great find,sounds really good too!reminds me of the national rx c45 i had way back when....
