    New toy!!

    yes, have thought of that as being a good ideea myself, but untill you do it, you might want to take that beast and move it on the top shelve, especially if you plan to runn it for extended periods. Don't forget to lift with your legs !

    they are rare because very few were exported to AU and Europe....actuly I learned that they were only exported to England and not to the rest of Europe. The British were also the only ones that got the silver versions of both, UC-1 and C-1. About the power consumption (you mentioned this on a separate thread)..700w vs 440w that you see on the Japan models and older US models.... I know of at least 4 flavors of B-1 rear panels. Japan and early US models will say 440w and all 240v models and newer US models (thinking serial number 1800+) will say 700w. The power consumpion stated on the box varies from market to market or point in time, to cater to the local codes. It really does not matter as all B-1s will consume more than 700w if pushed, agnostic of what the box sais. As a matter of fact, at over 200w, the B-1 sucks 1kw

    Yes. sorry to hear about the B-2. The B-2 has the sweetest sound of the V-fet amps. I hope you get it back to prime.

    Nice B-1 that will be singing for another 40+ years or hopefully more. The ZM K77s are somewhat rare.
