mr. miles

i used a different dc protect. the I've been using with my other amps. it is the relay near the small trafo. i used a small wire as fuse coz i cant buy a decent fuse holder in my place. the wire is rated 5 amps. i solder it on terminals that i put.

i also remove some parts for the dc protect.. hope you dont mind it sir apex.

thank for the designs you post.

still refinement on the amp coz my budget is limited..

more power
 
b500

greetings everyone...

this is what happened to my diy b500's trafo after loading 2 of these midtops in each channel and using it overnight in mobile application just last night...

regards
ees...
