The OC71 (driver) and OC72 (outputs) were alternates Pye used to the NKT types on this range of sets. Since you have the PYE P123BQ Trader sheet 1131 it's not worth paying for anything else anyway.
Any differences (if any) from the PYE P123BQ to the circuit will be minor.
The motorboating will be due to dried out Electrolytic caps.
I've sorted through 50c and €1 Charity shop belts to find closely matching leather to replace old straps, either re-using old clips or making ones.
