[Amps] Dentron MLA2500 Blowing Fuses

[Carl]

Id certainly stop feeding it fuses before you blow the transformer and 
find the problem.

As far as caps I wouldnt waste my time and money on off brand 85* C 
replacement caps. Quality 1058C caps from known manufacturers are only 
slightly more expensive. Ive adapted the CDE 381LX series to my MLA-1500 
and use them in customer amps also. Mouser and Allied sell them over 
here as well as United Chemi Con versions.

Some of the more creative persons have restuffed the original cans with 
the above snap-in style.
