Replacement CRT for the Ekco TS105
The original CRM92 in my Ekco TS105 is useless.
I acquired the set last year and experieced some problems with RF section, it turned out that the receiver is a TRF tuned to Birmingham frequencies.
There is indication on the back cover that the set tunes to channel B4
So the set must a TS1105.
I'm going to try an unused Mazda CRM93. I know that this tube is a 9KV tetrode and has a 12.6volt heater. It has a ion trap so some fiddling about with the rear CRT support will be necessary.
I'll report how the CRT replacement goes.
