HI GUYS THERE IS AN AMPCHOHOLIC HERE!!! Well guys I just got home this animal its a beats I like a lot very dynamic and organic amp , I jam yesterday with and I like a lot the low input the other one its good but I dont know the low input works fine for what I need it for I guess I have the cascade circuit!!! I am gonna restore it new grill cloth , knobs witch I already order and the handle but I been having problems finding somebody to sell me the faceplate so I will appreciate it!! but I have a major problem when I was doing the clean up and general maintenance that i do to every new amp I get like cleaning sockets , cleaning pots , tight up nuts etc.. ,I found that the main fuse was wrap on aluminum foil and burnt besides and I dont know if the Ht fuse has the right values so guys i hope you help on picking up the right fuse i been reading a lot some say that has to be fast blow some say its slow blow , besides that some say it should be 2 amps for the main fuse and some say should be 4 amp because change in voltage from Europe and the last thing what valves are the right ones a gut a the store told me that must have 6550 but it already has E34l's Groove tubes and sounds very good I haven had the chance to read about JMp and vintage Marshall specs Thanks to all of you ampchoholics for the support on this terrible habit!!!
