Dave - John - Graham . Right i will let sleeping dogs lie as they say .

But i need to fit one on to the function switch of the first Trio i purchased.
Looking inside both receivers you notice things that one set has ,and that the other one has not. Like the base plate is fitted with only 6 screws the other one has 8 .
Trio did things to cut down on the price . And there are more capacitors in the old set . Maybe its why it hums a little but its a 90% better than when i had it .They both are . Also inside on the chassis,there is this tag board that one of the the potentiomiter audio wires are solderd to ,that too has a capacitor ,But the other receiver cap is missing. The first Trio serial no has 3 numbers ,the last one 7 fig serial number. So i do need 2 to start with , to fit in the places i said that the cap is missing
