Stupid question time.

Could I transfer a power supply from a Pioneer LD that is rated to use 28W and put it into another LD player that is rated to use 37W ?

Would it work ? (Properly ?)

Cause electrical problems ?

Start smoking ?



Many thanks,

You can try to do whatever you want but if what you’re suggesting is even physically possible and the ratings are accurate then you’re asking for trouble. That’s a pretty big discrepancy. Bigger is OK, smaller isn’t.

I’d suspect that it would have issues starting LDs and changing sides, since those are the peak current demand times for an LD player. Audio screwups, discs not reading right, missing TOC info, no DTS sync. It would probably run the middle of a CLV side just fine but could flake out during the sustained current demand of a CAV side.

It could also potentially fail the PSU since these poor things are already decades old so combining that will over work…

VERICT: Don’t do it unless it’s a Sony.

If the schematics say you can then its OK if not then no.
These are made to specific electronic standards.
Some capacitors can be changed, microfarad values need to be exact. Voltages can't be lower than originals.

a power supply could have multiple rails with different DC Voltage outputs each with different current ratings. If any one of these are off, it will damage the electronic. Manufacturers won't waste pennies putting an oversized power supply unless it is some mega expensive audiophile device. If the nameplate rating is 37W, it most likely very well needed 37W to operate.
