STK module replacement

Got a nice JVC A-S7 amplifier. But one of the STK0055n final ICs died. A darlington pair. Seems most of the STK modules are no longer available. Has anyone come up with a board that discreet components can be used on, and will fit the original IC holes on the board?

OR

Is there a complete amp final available that can be mounted inside the amp and just wired in to replace the ICs.

This amp is rated at 50W per channel.

This company in Ireland has them at $65 U.S. each:

For that kind of change, I would think they would be Sanken new old stock and not knockoffs of some kind. I changed tons of those during the day (mostly Fisher 0080 and 0100), but even 20 years ago they were obsolete by my memory.

Alibaba lists the STK0055N for about $12 shipped:

I got in the habit in such situations was to always use a commonly available TDA7293, 120-volt, 100-watt, DMOS . Obviously requiring fanning out and sleeving the re-pinnning, into a bit of a rats nest and also if mute is used then often having to put in an inverting transistor stage in thr mute line.

That Alibaba one sure looks authentic! Well, maybe not so authentic... Like a poor copy of a copy...

Ali Baba and the 40 thieves is the full name of the original book if I am not mistaken...and an interesting name choice for a company!

Ali Baba was the good guy. The 40 thieves were, well, thieves. Ali Baba learned the secret phrase that the thieves used to gain entrance to a cave where they stashed their loot (as I recall).

True, he only stole from the thieves...which makes him the good guy...(?).

In a Robin Hood sort of way I guess. I'm 62 and read the story only once, and that was when I was in second or third grade, so I don't recall the particulars - but my recollection was that Ali Baba was the good guy.

Yeah, he was the good guy in the story.
