HI Eddie, exceptional video, great job. Thanks a lot for sharing. 👍

[@KissAnalog]

Thanks so much!

Hey Eddie, what's that green meter on the bench? Cool video of temps of the components, show up good. 👍👍

[@KissAnalog]

I will review that meter very soon. Here was a short that I did on it: kzbin.info7J-6V1IzwSE

Excellent thumbnail! This should be your most viewed video ever just based on that! 💥

[@KissAnalog]

Thanks! My Wife has taken over my thumbnails;) I think it is obvious when she started that;)

Interesting! Given the varying emissivities of materials, I wonder how accurate the indicated temperatures are. It might be informative to compare a thermocouple or other contact thermometer to the video for various components to get an idea of just how much you can believe the video temps.

[@rogeronslow1498]

Absolutely agree.

That's a great point - and I usually place electrical tape on shiny metal surfaces like the heat sink and the top of aluminum caps. I've been doing this so long and have made comparisons before that give me a pretty high level of confidence. I'm usually not looking for exact temps but looking for what parts are getting hot, and then checking to be sure that the temps don't go to high (with a 10 degree tolerance or so). If I want to know the temp to a tighter tolerance, I will use a thermal couple to compare my IR measurements to. The camera is just a great tool to see the whole picture and help illuminate (pun intended) the parts that might not have been suspected to be on the hot side. I'll do a video and compare the measurements. In this video I used a temp probe to watch the temp on a class A amplifier heatsink. I needed more precise and local temp to see how thermal grease (applied correctly) made a difference.

With open case it is easily posible you can get higher temperature of components then when case is closed when fan is on. Slots on case direct how air will flow over components, we had case when moving slots just 5mm reduced temperature of components for 30% (or over 50% then when case was open), with fan on.

I'm glad that you brought up this great point! The cooling system design is based on air flow and it does change it when the top is off - especially I think when the air is pushing in. I will have to test this at full power with the top on to see how long it will run before shutting down - if it does.

Recently, I have been simulating Blameless with 2 output pairs, emitter resistors 0.1 Ohm, +/-45V supply. When properly biased and idling, CFP output dissipates about 0.4W of heat per transistor. EF2 output dissipates massive 11.5W per transistor while doing nothing. I need six channels (24 power transistors). So the difference is 10W vs. 275W. I have to make CFP work.

Very interesting! Sounds like you have a challenge;) Thank for your feedback!
