Denon AVS486 Diodes

[glen65]

Hello,
I’m currently working with a Denon AVR-486
receiver. I have already found out what’s ailing
it, but I’m having trouble identifying two shorted
surface mount diodes which are connected in series with
each other in the output section of the unit. The
outputs being used are Sanken 2SB1560 and 2SD2390
and a 2SD947F in between as a driver.

The schematic designation numbers of the diodes are
D101 and ZD102 (zener diode) below is a pic of
of the two diodes. The zener is marked 82 and
the other diode T4.
I’ve already looked at different things that supposedly
decode the markings but the results were so much
all over the map they were no help with identifying them.
I just wanted to see if anyone has the service data
on this unit to find out what exactly I’m going to
need for replacements.

Thanks
