Here is my list, my order was from Mouser, total was 75 chf which is about 75 usd or 65 eur.
Dear Bert 1100, don't know if you still read this forum but thanks for you PM750 DC "Rescue".
I did the same job on mine, it was working, not defective, but forgotten in the garage because of a loss of interest and not-so-good sound compared to an old Sansui AU217.
Recapping the unit changed a lot this amp, especially on the low end ( power supply surely ).
I did something more that may be of some interest : just for fun , I put a DIP 8 support for the 4558 AOP on the driver stage, and tested the results with several other amps, as the design allows it : NE5532, OPA 2134, OPA627....
I checked with good headphones and the noise level is quite reduced.
The best uprgade regarding sound upgrade seems to be OPA627, mediums are softer, highs are great, but anyway each tested AOP fitted there is worthwile and quite better than this old 4558.
This amp, now fitted with new banana terminals for speaker 1 set definitely sounds better ! i can post some photos if someone is interested.
Thanks again Bert for posting your nice work!.
Regards.
Nicolas
