Turning into 200 scopes guy on ebay suddenly.

Challenge accepted! 

Edit: incidentally had a serious conversation with SWMBO last night and we both decided we need to move so going to bail out of London next year and get somewhere larger. Hopefully enough space for a scope room

That would nice, a lovely bank of them all displaying various tracers all at the same time 

So what scope did you land today then another 475?

[bd139]

Indeed it would.

It's not a 475 but a pretty cool machine. Will stick it on the TEA thread later

Update on this one. found out that the z-axis problems originated on one of the actual sockets on the boards. I resoldered the centre pin and we're good. It's not 100% perfect and drifts 1 div to the right on fastest sweep but that's absolutely fine as you can fix it with horizontal. It's certainly good enough for an ancient bit of kit like this.

All done and working

Great, fixed 2 scopes this week and power supply, you're cooking on GAS and having a TEA party 

[bd139]

Haha yes. Got another two things on the eBay watch list already

[Specmaster]

Oh yes, whats that then, a garden shed and a camp bed?

[bd139]

I should probably add them
