Thorn used a couple of thick film units in the 4000 chassis. i had one for repair, a frame fault I think.I got a replacement and cured the fault, but curiosity got the better of me, so i dug bits of encapsulation away untill I was able to extricate the faulty item (a transistor possibly a resistor as well, long time ago) and I successfully soldered in replacements, fitted it and it worked OK. I then put the new one back in, keeping the repaired one "just in case".
They did not look the same as your two being fully encapsulated.
