[ARC5] SCR-274N side tone level?

[David Stinson]

Try what worked well on the TCS set.
Connect two 5V Zener diodes across the headphone jack, one 

pointed in each direction.  Made the headphones on the TCS 

as comfortable as any other ham rig.   Lots of talk about how

“it won’t work,” but it works just fine.  I don’t explain it;

I just report it.  Pic:

Okay guys I need to reset this whole conversation in my original post I mentioned that the CW side tone was too loud along with the phone side tone. My main concern is the CW side tone because I wear headphones while operating CW and the side tone is just ear piercing. So I did some test on the CW side tone, and was able to lower the volume with no problem, but now relay clicking in the headphones is prominent. Funny I didn't hear the relay clacking away in the headphones with the loud side tone:-), fix one problem another appears oh well. Anyway think I'll just let things be have to remember these are WW2 radios not some $10,000 2019 Icom and that's why I like them their quirky, and rough around the edges.
