So, at least I am consistent...? Just finished assembling a v3 and a v5 this weekend. On start, get a high pitch sound (oscillation?) out the speakers if vol is fully counter clockwise. If vol is mid-way, just normal volume, and no high pitch sound. The speakers are nominally 4 ohms.
If i plug in my headphones (8ohms), a very short buzz and then normal volume control operations. Double and triple checked the vol-hi + vol-mid wiring, and even switched them, no change.
The switch between headphones and speaker is typical mechanical based on the 3.5mm jack.?
The calibration settings are set to "typical" (I destroyed the original values during one of my "experiments").
Was thinking of trying a small resister in series with the speaker.
Any other suggestions?
