Does your TR-4 have separate USB and LSB filters or does it have the "soupcan" style filter?

Hi all,

I picked up a TR-4 at a ham flea market for really short money. I was thinking 
of just keeping it for parts but it is all there physically and does work 
somewhat so I have decided to try to refurbish it. I have three problems with 
it. Two I assume are related and one that is separate. the first two are loss 
of receive sensitivity on all bands I can receive strong signals fine but there 
seems to be no band noise and of course weak signals are not there. When I say 
strong I mean s 10 or above on my other TR-4.
The second is the s meter is not working with respect to not being able to zero 
it and it will not indicate a received signal. With the meter zero control I 
was able to get the meter which seems to be working it?s self to between s 3 to 
s 5.
The third problem is that in SSB to get proper modulation I have to run the 
mike gain up about ? of the way using my Sure 444 D mike that works just fine 
on my other TR-4.
