Tek 502A in need of a trasplant

Post by Jorge Rodriguez » June 13th, 2018, 5:35 am

Hi to all,

I am new in this forum, a friend of mine tell me about a group of wise nice people.

I am restoring an old tek 502A tube scope. And I need some help: Its HV transformer is death, it has a burned winding and it makes sparks - really nice for a christmas tree but not for a scope, defenetely : (
The rest of the scope is in good shape, its CRT is almost new, its power supply caps are like new as well and I change death tubes for NOS ones. So, lets say its like a brand new blind scope.

So I would need your help. From my point of view the options are:
1. Buy a working HV transformer. If any of you have one and want to sell it, I am interested.
2. Restore it. It is cover by wax, so it would be difficult not to break the little wires.
3. Manufacturing a new one. I have no idea how many turns it has, wire diameter...

So, where do we start? What is your opinion?

Waiting for your answers.
Thanks a million guys!!
