Hi, I have a JCM-800 all original and assume is 2013 made, the serial number is M-2013-05-0216-1, I like to know what brand and kind of transformer was installed in this specific amp, and if is able to support kt-88´s tubes?
Hello Jaime,
Your 2203 was manufactured in 2013 week 05, as we have never used KT88 in the 2203 with this transformer we cannot guarntee the performance or reliability so we cannot recommend it.
