Hi Trevor
I remember Pitrie tubes being exceptionally good and the tube in your TV24C gives testimony just how good the tubes were.
Perhaps Pitrie was a brand name used by one of the main tube manufactures?
Having a common vision and sound IF amplifier followed by two stage IF amplifiers should ensure that the performance of the type 63 receiver unit will be excellent.
Early production receivers had IFs of 34.5Mc/s vision and 38Mc/s sound. Later production type 63 receiver units had the BREMA IFs of 34.65Mc/s and 38Mc/s.
