No selectivity/Sounds like crap

[mr_fixer]

It didn't, it was there to roll off the high frequencies. it sounded much better after i removed it. In your schematic it is c29 the .005 mfd cap. from the plate to cathode/ground. also there is a 220 pf cap number c14 that also rolls off the high frequencies in the driver tube. i would try removing it also. I don't know if peoples hearing has changed over the decades. it makes me wonder if you could take a modern stereo back to the 1940's if people would complain about too much treble. The telephone Co. has limited freq response to 4k for over 100 years, i wonder if people were used to that response and radio manufacturers made radio sound curves to match. I dunno. Logan
