I've got a wierd. TR7 s/n 1087 Filters are 1.8K in A 300 or 500Hz (don't remember which) in B some value of capacitor for AM in C
With radio set to LSB and filter A I get a whistle of around 2KHz which disappears if I reduce the RF gain control to below around half way. The PBT control will drop it off either side of the filter.
No other control combinations affect it. -- Nigel A.
