Specmaster:
I collect this beast today and after a day out in Cambridge with the family, finally got it home and powered the sucker up, here are some shots of displaying 234MHz sine wave from my Advance sig gen in digital mode, a shot of an analogue signal (far nicer), a quick glance inside reveals a conundrum, some IC's are dated 96 ut there are also a significant amount dated 98? There is no sign of any previous repair work being done so was this a scope made in 98 but with some left over 96 chips, or was it a 96 left in stock and then taken out and some options added in 98?

The main enclosure is plastic but the outer casing is metal, everything seems to be working just fine, now all I have to do is learn how to drive this and decide which of my other 3 scopes is going to make way for this one. I love the accuracy of the Advance sig gen as can be seen in the last 2 photos, the display reads 11Mhz and the sig gen also indicates on the pointer, 11MHz, bobbie dazzler.

It does run very hot though after an hour or so the top is very warm to the touch, unlike any of my other scopes, although the 1740A is nearly as warm when it runs but the Hitachi and the Iwatsu are just warm. The caps all look to be in fine condition visually, no signs of bulging, discharge, venting, discolouration etc and the insides are extremely clean as are the fan blades.

EDIT UPDATE It seems that it is indeed a 4th May 1998 model because thats what the screen displays when you ask for the model details etc from the menu, so I guess they over ordered IC's in 1996 and were still using the stock 2 years later?

That looks in great condition. In fact, it looks like another Specmaster Special, good find!  :-+

Thanks, I've had my fair share of lemons so I suppose it the law of averages. Got my eyes on yet more items  :-+

I love that PCB, so obsessively neat. If you had to fault find anything on that it would be a pleasure.

Specmaster:
That's the only board that is fairly accessible though, the others need expansion cards which are going to be like pixie dust to find.
