Panasonic PV-7664 audibly noisy in operation	Can't Post

PV-7664 makes loud rattling sound whenever drum is rotating, however, it function satisfactorily in all other respects. Preliminary visual inspection shows nothing obvious. Sound is apparently coming from drum assembly, or something beneath it. I see nothing else apparently loose or shaking. I have not done any disassembly aside from removing the top cover.

Thank you. Is there any not too complex fix?

Replace the lower drum assembly (or whole drum assembly).

Thanks again. How complex and expensive, is this likely to be be? Will it require realignment? Require instrumentation realignment? No clue how to do it. I assume it's not a simple remove and replace, right. I guess I'll need to trash it if that's the case. Much appreciate your help. Too bad, as it never did get that much use. Hope to hear back from you, and appreciate your time.

Many have plug-in connectors. You should be able to determine once cover is removed. Unplug, remove screws, remove assembly. Reverse for reassembly. No alignment, just be careful with the heads on the upper cylinder.

Very encouraging. What, where is the best source? I can then decide if it's worth it to me? If you're in south central PA, stop by for a 6-pak.

Obtaining replacement will be a problem (New/Old Stock from some obscure electronics parts supplier), but pulling one from another PV-7664 off ebay can be one way. (PV-7661 ?Possible alternate? Same service manual covers both but may or may not be same assembly).
