Just got my used WT-300 in the mail. i wont be able to really run it through its paces until next week when i can get my hands back on my "good" cab. HOWEVER, i have some questions for you. 1) It's a little noisey. there is a buzzing that i never had with the same bass/cab and my other head. bad tube? is this typical of edens? 2) what are the auxilliary input jacks for? One says LEFT and the other RIGHT... so far as i could tell, this isnt a stereo amp. What do you guys use these for? 3) MOST importantly to me- it is used and shows signs of having been opened. Some screw holes are present and i dontknow if screws are missing. i see a triangle of 3 holes on the left and right sides - these are surely for the rack ears. NO probs. HOWEVER, there are 4 screw holes (in the shape of a large rectangle) on top. is this normal? seems like something is missing. Did it have a handle? lastly, there are a few screws on the bottom that have similar sized holes less that 1/4" away. whats the deal here? the amp was made in 98. Before i complain to the seller, i want to get educated on this. if anyone could email me a picture of the TOP and bottom of their wt-300 i woudl be gratefull. or, if you think you could help, by all means reply and give me some insight. thanks a ton. ps- soundwise i like it so far, but the cab i have here is total crap so its hard to judge.
