I personally haven't seen these fail, and don't have the specs of the diodes
on hand. I wouldn't bother "upgrading".

Just have MPSU10 and MPSU60 on hand.

I don't know if the 1.5 Ohm resistors was just because of a parts shortage,
or what. I have seen the 3ohm resistor versions; there is usually that
"glue" between them. I will say that I've seen the 3ohm resistor versions
crack from heat, but I've never seen the 1.5Ohm teepee fail that way.
Considering the parts layout probably assumed a 3ohm resistor version, and
then the 3ohm resistors cracking, I guess one could speculate they decided
that the 3ohm resistors weren't working out so they tried the 1.5ohm in
series to separate them a bit.

Sorry I don't have better answers; I'm pretty much tapped out of G08
information.
