Philco Model 48-1256 Humming and no sound from speaker
#4

Ok, so I took it to Maunz Electronics and he told me exactly what it needs repaired. Unfortunately, they couldn't find the parts. Can anyone near Columbia, SC help me? It needs 3 caps: 10uf 250 vdc, 40uf 450vdc, 15uf 250vdc. It also needs Vacuum tubes 7C7 and 7A8 replaced, and the phono pick-up cartridge needs to be replaced.
