Acoustat Model 3 Issues

[malthuse]

I recently got a pair of model 3s and I’ve found a few issues I was hoping people could help me with.

1) One speaker is quieter than the other. For this is assume it’s the diode/capacitor board that increases the voltage. Can someone tell me what would be good replacements for these components.
2) The transformers hum. Is this an issue?
3) I played one song that had some deep bass. The quieter speaker made a weird sound at the bottom of the speaker on the lowest notes. Sort of like distortion but vey localized to the bottom of the speaker.
4) There are some other real old looking capacitors in there. Which ones should I replace?

Thanks

Stop playing the M3 interfaces!
You can kill the Transfourmers trying to drive low bias.

Oops
I found that one of the leads had popped off when I put the interface on. That explains the imbalance and I think the bass sound as well. The only issue now I’d the transformer hum.

I assume it wouldn’t hurt to replace some components or should I leave them.
