[Heathkit] Power supply parts for SB-200

[km1h]

Obviously you dont understand electrolytics, their temperate specifications 
nor other rating data.
The original Nichicons and others used by Heath are so far superior to the 
ones you mentioned it is not even close.

I was trying to be helpful and suggest the proper substitute so as to not 
cause a potentially serious failure to an amp.

Do as you wish; hopefully others will think twice before going Cheeeep.
