pass labs xa25 polarity
The gain at the speaker terminals was to spec at 20.4dB, and the output preserved absolute polarity (ie, was non-inverting). https://www.stereophile.com/content/pass-laboratories-xa25-power-amplifier-measurements

Tubes though are easy to plug in and out. They can be changed. So audiophools change them. Because they can. Which is exactly as good a reason as it sounds- no reason at all. The same apply to FUSE? 
Poor internet, streaming not possible

Krell Evo 302e amp shutting down afeter about an hour!!
The Krell Evo amp is capacitor coupled. So, should I measure the DC offset with the speakers connected? Your Krell Evo amp is capacitor coupled on single ended rca input, NOT at the OUTPUT, so no need to connect a load for DC offset measurement.

Krell Evo 302e amp shutting down afeter about an hour!!
1. How can I measure the DC offset? I mean what is the procedure to do this? https://www.wikihow.com/Measure-DC-Offset 2. Is there a pot o pots that I can adjust to lower the DC offset? You need a service manual or call Krell for the procedure...

Stuck at home? Make a kit!!
Got kids at home you need project ideas for? Just keep the solder fumes out of their faces, and use lead free. :) No kid at home? Make one! No tools required. :) 
Question re: Phono stage gain and possible new integrated
Or will this be too much for the LFD’s gain? My Hana is rated at 2.5 mV. If your Hana is a high output MC, you should use the MM setting 39dB gain on your LFD. 
Cart match for sony pua-114 tonearm
Between Denon dl-103 or dl-301, I will go for dl-301. Dl-103 need a heavy arm to sounds its best.
