3457A parts wanted

[tppc]

Hi all,

I posted the same request in the repair section of the forum and have been adviced to post here instead.
So, my question is : does anyone know where to find the following parts at reasonable price ?

- 1QF6-0066 A/D hybrid (A2 U511)
- 1820-3549 P8051 MASKED (A2 U501)
or
- 03457-66502 PCB Analog assembly (used)

Thanks for your help
Kind regards
