Delay Line Issues

[bluenorm]

my ctc 16 (gf629) has displayed the same symtoms as of jon 1967us. i purchased this set about 20 years ago. high hours and with a zenith tube and the has the same issue since day first.
upon recomendations from old-tv-nut the following discoveries are;
R65 factory @2200ohm currently at 1.9k (ok )
R66 factory @150K currently 140K (ok)
L14 factory @ 6 ohm currently@ 7.3ohm (not open, pass.
and the surprice is R64 factory @ 10K currently is 1.9 (not pass as stated by old tv nut)

next is to remove the chassis and check L13 right after delay line. check post electrolitic voltage and R102 and other resistors. replace parts.

is there something that i overviewing please let me know.
