Hi All
I am repairing a AMI Rowe R-82 Jukebox for a friend.
There are 3 capacitors of which 2 are suspect, one definitely blown.
Replacing all three.
All are axial electrolytic.
They are all part of the main power supply for which there is no circuit in their repair manual.
The PS delivers:
28vdc 3A fuse
-27vdc 1A fuse
-7vdc 2.5A fuse
The first:
Sprague 70023310
1250UF -50vdc
Physically 50mm long & 25mm dia.
Sticker says Aug 1977.
Should be easily replaced.
The second:
Mallory 3000MFD 15vdc
S-235K
235-7731B
Physically 40mm long 22 mm dia.
This one is a puzzle to me. 3000 milli Farad ? (3000,000 micro farad) in such a small package ? What is the chance of the marking meaning 3000 MicroFarad ?
The third:
Standard 220uF 80vdc
Does anyone here have any idea on the second cap ?
Regards
