Re: Absolute beginner Q's: sensitivity at lower AC input
It all sounds very promising Paolo.
Yes, you should expect lower gain from all the stages at reduced supply voltage.
Run it with the lamp-limiter a while longer hopefully the electrolytics will reform, replace C17 because it could destroy your output tube and transformer if it fails, then I would just connect it normally and see what it's like.
It could be that the variable capacitor shorts when meshed, but maybe the local oscillator stops running because of the low HT and LT, although it's usually the high frequency end of the band that suffers.
