Hi Mang Tony, I believe it was not. It's case of over excitement, the AMX was my first tube. LOL
I just sent Andrew an email, I only had the amp for like 15 minutes (it was hand carried by my parents here in Canada) and have been collecting dust since then.
I can tell everyone that is a nice sounding pre-amp hence I hate just to throw it away.
Andy, or s2kov is also settled in canada right now, if you can touch bases with him via pm here, maybe he can help you...
