Nonsense ! He could move all his stuff into it 
According to the other thread, Hatfield is a smokeless zone so check which way the wind is blowing before lighting it.

Distortion is -80dB (0.01%) 2nd harmonic (3mV in, 250mV out)
Getting some hum from somewhere, need to plug it into the system to see if it’s actually there or due to the measurement setup as I’ve had issues with it before.
Frequency response is good.

I have a Flir plug in thermal imager for an iPhone if that would be any use.
Can’t hear a thing 
Thanks Frank. I’m reasonably sure I’ve got the diagnosis sorted though. The thermal approach (I simply used a contact thermocouple) is complicated by the fact that the disruption on the +5V rail seems to be causing all of the chips to run warm. More careful checking from a cold start indicates that most of the trouble is indeed in the two SMD ones (I’ve got other reasons to believe they’re sick) so if my customer decides to go ahead with replacing those then I’ll pop over to my friend with the Metcal SMD tweezers.

At my last count you had two, plus easily enough arms and cartridges for them. And before you say it, at least I have one working horn system
