Right thats got your attn. In the 'doghouse' underneath a 130 what filter caps lurk here? be helpful to know before I get the hulking great beast apart for a looksie before I plan a recap.
Does anyone have a capacitor list of a MM 130 amp? I have the SS 130 (2275).
Thanks, B-Jilm.

Mike Im really confused with this as I have found -only- two 450v caps in my dawg hoose. Two 100uf Mallorys.
On the 2275-130 schematic (from the Musicman site) Ive gone over countless times searching, but I cannot find FOUR caps of 450v, only the 100/450v C44 and C45.
What adds to my confusion is there are -four- splodge marks (cap mounting black gunge blobs) on ma darn doorty dawg hoose ceiling, indicating ~bizarely~ two mystery ghostcaps!! but schematic there are none.. I dont understand.
Im scared.
