Question about Technics Audio Players & Recorders
Technics CD player SLPS840. Can the original Technics opamps M5238FTA and M5219FPTA that sit in the buffer amp of the line output stage be upgraded by replacing with National semiconductor LM4562s without any problems??? Cheers Steve W.

this is a standard plug you should be able to get from radio shack or other electronic stores. just take a picture of where the connection is on the unit with your mobile phone and show it to the sales person. cheers, mark

yes they need unsoldering from the board and new replaced if needed but you should be able to solder the ones that are already there just check for loose connection on them

these models use the 12.1 philips laser mechanism and your right it is a very common problem.
various marantz / philips / cyrus cd players etc also use it and are plagued with the same fault.
it's a 90% chance the laser is dead!
philips realised the unreliability of this laser and uprated it to the identical looking VAM-12.
do not dismiss the spindle motor as these also fail quite alot on this mechanism.
hope this helps.
