Information for the Ekco U353 can be found in the 1960/61 Radio and Television servicing book, pages 82 and 83.
Tricky faults to find. The problem could possibly be caused by one of the the three 15pf tuning capacitors in the 10.7mc/s IF transformers. The secondary of the final 10.7mc/s transformer is tuned by a 22pF capacitor.
Have you checked or replaced the UABC80?
