Yes, this is a very good solution! I had to do something like this but
without the summer/winter switch when I decided to modify an ARC-5 BC453-B
WWII receiver for SDR. It had occurred to me that it would be a good idea
to explain to a local club how easy it was to convert the old radio to SDR.
I proceeded to remove all of the original internal components from the
BC-453 and then put a Flex1500 plus power supply plus cooling fan plus
speaker plus audio amp in the box while carefully maintaining the original
appearance of the old radio. I used an "on line purchased" small audio amp
and computer speaker without giving thought to what I might be doing to the
audio out of the Flex1500! Not at all smart and it resulted in an unplanned
visit of my 1500 back to Austin! But that capacitor should be a word to the
wise!

A capacitor in-line of sufficient rating to handle the voltages to be
encountered and with sufficient capacity to pass the lowest freqs of
interest will turn off your ear heaters. Maybe you want to wire in a
"Summer-Winter" switch to be able to select cool or warm operation as the
seasons change.

Heating in headphones and speakers is usually caused by D.C. coming out of
the amp. I underline usually maybe something I'm not considering
though.....

Anyone else use earbuds? I've used a set for years with my Flex 3000. I
now have upgraded to a FLEX 5K and when I stuck my earbuds in for the
first time, they were very warm. I thought I had them leaning against
something warm in the shack, but after sitting on the desk for 10
minutes, they are still warm. My ear canals won't get cold, but
clearly, there's something strange going on here. Any ideas?
