Hello
I plan to replace power supply diodes in a Linn LK280 amp
They use MR752 diodes 6 A (Ta) 22 A (TL), 400A (IFSM) I was planning to use MUR860 rated 8A (Iav), 100A (IFSM)
Should I only compare MR752 6A to MUR860 8A specs ?
Is it finally safe to replace the MR752 to MUR860?
Thanks

The 8 A rating seems okay. There is one more rating to take into account, Reverse blocking voltage, Vrrm or Vdc. Replacement should be as high as original, or higher. AC lines in the western hemisphere have transients on them as high as 1300 V from A/C or refrigerator motor shutoff. That gets divided down through the transformer to a lower voltage by the turns ratio. So generally 400 Vrrm rectifiers are okay, although some brands use 200.
If what you're talking (Vrrm) is the same as (IFSM), the MUR860 has only 100 so it could be risky ?
