i just reached out to hallicrafters expert Chuck Dachis , i totally forgot he was the one who confirmed with me my conclusion that the another radio of mine (S38-d) had an error on the schematic.
today i am focusing back on the IF T10. I have 100pf caps installed. as a result to achieve max volume the slugs need to be bottomed out.
This must mean the IF does not have enough capacitance accoring to Terry which is a great god like epic super hero here to me.
we considered some options to solve the low volume issue now that i was forced to omit my oem silver mica cap.
the radio is trying to tell us to increase the capacitance in order to be able to back out the slugs some.
I installed 150pf on each side of the IF and the volume went up some.
i installed 200pf and with the vol knobe at max, the sound from a local station feels like the knob is at 60%.
if i open the tuning caps and inject the freq gen, the noice coming out of the speaker is unbearable with the vol knob at max.
Maybe Chuck will help my cypher this more as well.
