Just a thought on the 1400 chassis. The local distance control works on 405-line VHF only.

However, if Tag 43 is moved to tag 44 allowing 625-line VHF reception, not only do the 405 and 625 contrast controls work but the Local Distance control becomes functional on 625 UHF!

Worth doing this if overloading is apparent which is a possibility with modulators.

405-line VHF works just as well. 625 VHF reception only works if the supply to the system switch solenoid is disconnected
