I don't have fin temps, but I do have a few device temps. I have them somewhere I can post them once I shake the flu When measuring toroids it seems that the highest temp rise is between the potting compound and the side opposite from the wire leads. I finally gave up on my IR thermometers and bought a pyrometer that I can touch directly to the device I want to measure. This seems to help getting accurate measurements.

Moving to vertical finned heat sinks is enough to make the thing run a lot cooler. I worry most about my transformers, they run hotter than I would like.

I would replace the bad one first and go from there.

Is there a Headamp trade up plan?

Likely the expensive one in the right channel went bad I can verify when I can grab the schematic.

The new Airport Extreme can have a USB drive connected that can work as a Time Machine server. Probably the power savings over the G5 will cover the $200 cost.

Is reliability really that important these days? Backup to an external drive and use cloud for some stuff as well. Anyways I would make the SSD non negotiable. Same argument as above with regard to size, shouldn't need much really.

Heh. I would suspect something is wrong, yes.

I didn't ask what they were around, but what they measured. I want to see if you suck at randomness or need better matched devices. Pick a bias and compare. If you want post a min and max value across all the values.

Can you post the voltage drop across each 10 (2x20) ohm resistor for all four channels?

Sweet. Advertised 10% THD.

Anyone have the cheapie Shiit DAC for sale / trade / demo etc.?

If it is 80 mA DC then 150 mA RMS isn't overkill at all, it's a bare minmum.

Is the 150 mA specified as AC RMS? What is the DC current draw of the amp?

If one of the SK170 is bad (my guess) I can match a new one for ya.

I have the manual just can't upload it from my phone to Tapatalk and I am lazy. PM me your email addr.

Measure the voltage drop across the four 22 ohm resistors that degenerate the four input 2SK170 to start with. Also the 10 ohm near the 2SK389. Compare channels.

I believe he has a "crib" there.

Huge difference between -15 and 15

DC heater with like 1VAC ripple might be proprietary. AC-DC heaters ?

Car wouldn't start today. Battery was too cold. The issue was it was blocking the car that was in the garage. Said frozen car wouldn't shift into neutral either. So, sorta held the shifter down and shoved it towards N and it would kinda move assuming lots of pressure in the shifter.. So, backed one car into the other to help move it and an Austin Powers esque scene ensued trying to get the one car out around the other car. Finally after some slight damage and blocking the street for a good while, was able to jump said frozen car. Yeah. It was not fun.

Would be fun to populate the four outputs and the input and see how high you can get THD+N. I bet you could do 5%.

So much snow fail today

Shit?

Hard to describe why this is the case, but they ran out of places to put the snow where I live. Heh. Also I inflicted what felt like someone slamming my hand in a door by not wearing gloves for like 5 minutes and shoveling snow. Ouch.
