Can anyone help with identification of the component as represented by the symbol to the right of the IF amp transistor, as shown below. I've no idea as I can't say I've seen this symbol before, is it part of the IFT?

SAW filter? They are somewhat lossy devices, hence the use of an IF preamp between tuner and filter.

@turretslug Agree it’s a SAW filter, the 39.5 indicates the vision IF and the circuit designation is SF131.

Definitely a surface wave filter. Used in Thorn TX 9 or TX10
