Hi Steve,
That's a nice looking set. The chassis looks very clean from the back.
I used to have a TV53 and once restored a TV62 for someone. Nice sets to work on and I'm sure you will apreciate (as we both have a T36) a vast improvement on the previous range (T36, TUG36C, TV43 etc) in terms of servicability.
These sets can give really good pictures, but the CRTs can be a problem if they develop an internal heater short. You can check this by measuring the AC heater voltage on the CRT when the set is running.
Keep up the good work
Cheers
Andy
