You have a fine taste for the good things in life.

For the not too young a 5 1/4" floppy disc would have been a good size reference

I was thinking cassette tape - used those long before I had a disk drive ....  but since you asked

A Pickett N500-ES slide rule

Can't find the Pickett, but here's a Sterling

Filling the Rack, there is still some space left, let's see what goes in there...

That new scope seems way too small for the available space. 

[Martin72]

I could fill it up with 2 more SDMs...
A second rack for the other side of the table would also be conceivable, where I could accommodate power supply units and loads.
The scope is too beautiful to hide it in a rack.

There's 2 more products coming soon that might help with your requirements, SPD4000X PSU's and later this year a SDM4065A, both in dark clothes so to fit right in.

Thank you, very illustrative!

I just bought a Harrison Laboratories 855B Power Supply. Out with the old homemade bridged variac. In with ..... an old ....

Oh, those are lovely! Pics by any chance?

Hi Exe, I just saw Your reply, Here is the Harrison that I bought. It works perfect !

[DiodeDipShit]

I forgot to mention, the above power supplies on/off light out. It is a tiny 117v something. It is only 3/16" in diameter. Does anybody know its manufacturer and part number? Or where to source a viable replacement?

[DiodeDipShit]

I just bought a pair of Rogers LS6a Studio 200w speakers with 8" woofers . They Sound insanely Perfect ! ! !  Their small package is very deceiving.  INCREDIBLE ! ! !
I Just have to finish refurbing my H.H.Scott R77 and get the whole system up to the living room.

Forgot to attach this pic for the above post.

Nice British HiFi speakers. Rogers used to work extensively with the BBC, manufacturing (some of) their monitoring speakers. I don't think the LS6a was directly used by the BBC, they did develop the LS3/6A though, which had an additional midrange driver. The LS6A uses polypropylene woofers which are much nicer sounding than the older over-damped bextrene drivers of the era.

Looks a lot like a neon indicator/lamp to me.
If there is a resistor buried in that black sleeve (behind the red diffuser in your photo) then it is almost certainly a neon.

Just brought home a HP 7550A Plotter. The mightiest beast in pen plotting aside from the stylish 7580. Only thing missing is the paper holder for the backside. Anybody able to make some pictures of theirs so I can DIY my own?

Lol, I just purchased one of these as well.  I believe it has the part you are missing.  As soon as it arrives, I'll 3D scan it for you if mine actually has it.

Mr. B, Thank YOU for identifying this bulb ! !  Neon makes great sense.   I have a feeling the resistor disintegrated as only the black insulated wire You saw behind the lens was left dangling and fell off as I was taking the bulb out .... and there wasn't any remnants of the other lead. The resistor must have escaped out of the big ventilation holes and headed for the hills.

Looking through my ancient collection of miscellaneous electronic things, I found a couple neons soldered together. The first try went zenon with 10k ohms. Luckily it's siamese twin looks pretty good with 70K. By jove I think Your 'brilliant' Mr. B ! ! !

8 assorted DSO's, 4 AWG's, PSU's plus other assorted bits and bobs. <a small order this time.

Thanks Gyro,  You enticed me to look up early Rogers BBC monitors and found that those are quite rare going for thousands.
Note that these LS6a's that I bought are Black. I was told they are sold to recording studio's, no fancy wood, just beautiful sound......

Holy sh*t did I get a deal ! ! !

[RAPo]

I've bought a Gerber Octane.

[exe]

Bought some resistors from aliexpress for my picammeter.

I can't check 10G resistor with my equipment, but 100M and 1G seems to be good-enough (1G is connected to 9.84V battery, no shielding).

One problem I’ve had over the years is the office pneumatic chairs never go high enough to comfortably use the microscope sitting down.

I’ve bought a draftsman chair from Amazon, this is superb.

Pics at both its lowest and highest where it’s  almost touching underside of table (table is 75cm / 29.5” high)

Plus the arms lift up out of the way.

...third lens came today - same model as the first, but this time a definite fault.

... very restricted travel on the focus ring, a few degrees of turn (from infinity to 1 metre).

described  as in good condition, 4 out 5.

...for those keeping score

England 10
Japan 7
France 0

...low score may get better - depending on recovering the cost. It was the most expensive of the three.

 

Confirmed zero - and ebay are heading that way too
