bd139, I do indeed have the blue one, its a IG-4505 and she is in all of her original splendor the modification made was to remove the pre-attached BNC lead with the 50 \$\Omega\$ termination resistor with a BNC socket for more flexibility and of course easier storage when not in use as the lead always got in the way. I have made up a special lead with the 50 \$\Omega\$ resistor built in to retain the 50 \$\Omega\$ connection if required.

I have also recapped and cleaned it and thoroughly checked it over and tweaked the calibration to bring the output voltages up and now she is bang the money. Now of course having seen that IG-4244 of med6753 I want one as well. Not too sure which is the earlier one but I'm kinda guessing its not mine as if the numbering system went in chronological order, mine is the newer of the two.

That’s the jobby. Looks in fantastic condition  :-+

I’ll shout what I did five minutes ago “fucking hells bells”. Power supply just blew up on my 465. Took a bridge rectifier with it. Fuuuuuuu. And such is life i now have three dead scopes on my hands.

Sorry to hear that, and I feel your pain (i'm on 4  :) )

Can we have pics of the repair, please, you know they'll come in handy for quite a few other TEA freaks... me included. There's a 475 that looks in very nice cosmetic condition, claimed to be but not shown working, on the Bay for £120.... if you feel like you need to join me on 4 dead 'scopes.

I scored one for free.  Mine needed recapped as there were 2 bulging caps in it.  I also did the same BNC mod.  It probably wouldn't be a bad idea to tweak the calibration.  Yours does look a bit nicer than mine but mine is quite nice considering the age.
