Need help locating replacement LF Power Amp for load tester!

[jonnyGURU]

I've been looking all over for a Hitachi 1031(K) (same as 2SB1031K maybe?) low frequency power amplifier for the ol' Sun Moon SM-268. It burned out and now the thing pops any PSU you plug into it. Stupid little $2 part and I can't find one.

Any help would be appreciated, alternate part numbers, source even if it's in China, etc.

Here's pics of a burnt one and a functioning one:

I tried searching for it but found this linked as a related item on a parts site. The specs look close.
