Thanks for the excellent links. I googled trio kt-400 again and found a German site "Old Fidelity - HiFi Forum Classic". Someone there had washed the lettering off the front panel and were having hard time finding a refference. I would like to help him if I could, it was a recent post from October this year. Attila are you familiar with that site?
How did you guys find your info or is it a trade secret
?
Thanks again Al.
