Ordered! Thanks alot!
If this does the trick, i need your adress to send you a Norwegian candy treat!

I would definitely replace that one also, before connecting any other or repaired pcb. Or do you have 100% control of how your cabinet is wired?
Old capacitors could die by age (they dry out eventually), but the amplifier IC death is more concerning...

Yeah, it's the same PSU. A new one is allready ordered. (Can a computer PSU take its place, in theori?)
I have 3 "arcade PSU" at the moment, everyone is second hand goods and I no longer trust them.
The spaghetti (harness and such) should be OK, as I desoldered a brand new one and soldered on only the needed pins with a bit thicker guage wires.
The cab it self is allso stripped apart, metal frame is scraped/buffed and painted. The switches and fuse-holders (and fuses) replaced. Pretty sure it's no screw ups, but I'm doing a walktrough on the whole deal, I don't wanna experience this in a while.

I came to think about the amp.IC. The seller told me the game had a "humm" to it, but worked perfectly. This might be a early sign of weakness of this IC, no?

The hum was prob'ly from a failing pwr supply. The amp chip won't create hum on its own....unless its *very* close to catastrophic failure....which may have been the case. We'll never know....

As you said, we will never know..


Anyway, tiny components are arriving each day now.
I ordered from 3 suppliers, only the national supplier has delievered yet (Bunch of 1uf 50V caps).
A new powersupply and some other caps should be her next week, and hopefully the LA4466 not to long after.

There is only one thing I have not found yet. Think I even forgot about it, actually.
The main "bad guy" which actually blew up on the Toki board.
In this picture here: CLICK ME
The one that is totaly toasted, and on its own row. It's different than any other component on the board.
It's blue of color, and the only thing visible now is the text 16V. There is something written on the line over "16V", might be 422 or x22 or something. Pretty sure its 22 at the end.
I'm guessing it's one similar to the far right on this picture;


But how would I go about finding the correct value for this guy?

For the ones who is able to decypher such schematics;

Could it be the one marked C2 on page 3, which is refered to as SSG16-22F?

This is the board in full view;

It is definately C2 next to the 8080 processor.
