There were still 9-160 sets running fine 15 yrs ago when I did a one
week stretch in CCU.
Also had RCA CTC175 & they all had soft CRT's.
Replacements were Maggy LCD sets probably about 24" 4:3.
Those looked terrible even brand new. Rather watch the soft RCA"s !
The arm mounted sets were all 9" Zeniths with the last real Zenith
9" chassis. All the old Sony & Toshiba 5" were gone, very worn out.
