Hallicrafters S53-A
#44

I think i need to replace the two remaining IF caps and here is progress so far.
tell me if you think i am right ,  i barely know what i am doing here, this is OJT to me.
I open both tuning caps
I add a .1uf cap but have no idea what they mean by adding it to the high side of the tuning cap so i assumed it meant wherei have it now.
i inject the 455kc
over the past few days i have fiddled with the IF's slug adjustments so much they were totally jacked up.
I finally was able to adjust the IF slugs to get decent volume out but by ear its feeling more like 50%.
I use to be complaining about 20% volume with the knob at max so this feels like progress to me.
I peaked these three IF's (six slugs) by ear but since i suspect my ear is not good enough,,,,,next i added in my meter to the headphone jack and selected headphones.
I started over again peaking the IF's to max millivolt readings.
This helped get me to where i am now, the vol knob is at max but the sound by ear tells me the radio suffers from some degree of low volume.
TO the slugs.........
I noticed in order to get where i am now,  nearly all my slugs are bottomed out.
I replaced the caps on my first IF which is T10 with two 100pf caps.
The other two IF's still have the silver mica stationary caps.
I only have 2) 100pf caps remaining in my hoard.
to the question now..........
would the remaining IF's T11 and T12 stationary caps being boarderline faulty cause a symptom of poor or low "ish" volume?
If yes, if you had only two 100pf caps, which IF would you trow your last two 100pf caps at?
Back earlier i mentioned a buy on youtube who thinks my last IF T10 requires a larger pf cap than 100.
I notice this difference........
T10 slugs have 12 rotations each of adjustment.
T11 and T12 have six rotations of adjustment.

I just harvested parts from our old Tube TV and on the circuit board there are many coin shaped caps in the 1kv and 2kv ratings, i will see if there are some PF caps on this board or other PCB's i have saved back for spare parts.
