Title: Anyone know of a source for new nintendo audio transformers
Post by: GMZombie on August 29, 2019, 09:22:21 am

Just as the sub says im looking to find a new audio transformer for mt sanyo ez20 monitor as mine i think is bad. When i check the ohms on each side and the 260ohm side is reading 40 ohms and the 8 ohm side is reading 1.4ohms. I have recapped my aidio board and replaced my transistors on the board along with theudio smp on the pcb. Still no audio

I used this... worked fine.  Probably overkill as it really is not the intended purpose...but I had one lying around. (I just used the audio section)

You could also just use one of those cheap amazon/ebay amps.  Run the audio out directly from your game pcb to the audio in on the amp, tap into 12v to power the board, connect cabinet speakers to the amp and you are gold.

I recently did this on a DK cab to eliminate the speaker hum.

Worked like a charm.

This would help as well...
