Telequipment were owned by Tektronix when this scope was made. I think some of the design people worked on the 22xx scopes so that might be where your problem is. Really shitty British engineering  :-DD

To quote a friend of mine who was dating a girl in Billericay; "Essex made me itchy". All is not forgiven yet :-DD

So you're saying that in this case, the shit rolled uphill?  :-DD Figures... If anybody can make that happen, it's ya'll "logic-be-damned" biscuit-eaters. :P

EVERYTHING stops for tea; including common sense.

From the info in that manual I've mentioned there's no need.
One can calculate the wire length from the resistance and if you've got a crapped out transformer you can measure the wire gauge and come up with the length. If I were you I'd only take an accurate resistance measurement and record it in your archives....isn't that all you'd need to rebuild one ?

mnementh:
I tend to agree; if I were going to unwind one to count it out, it'd be the dead one first. Only if I couldn't get a reasonably close count would I consider vivisecting a good xformer.

If we save the whales, where will we keep them?

bd139:
Fair points. The goal would be to produce a new HT transformer for it wound on a COTS E core. The ones in these have a Paxolin base which is nasty. I’ve done a couple of these before successfully.

I think I’ve negotiated another dead one off someone. They’re multiplying.  Well apart from the multipliers.
