Re: Calibrate the time base, or horizontal amplifier?
Harvey,
One of the main calibration issues that requires "exotic" signals Is the frequency calibration of the amplifiers. Having these be off can nuke the bandwidth of the scope. 465B 3db down 75-80 Mhz instead of 135 Mhz. (Yes I know 135 is above the 100 Mhz rating of the scope but that is what mine caled up to when properly adjusted.) These are done with fast edge square waves. 1ns rise time for 465 and under, ps rise time for 485's and faster for even further up the BW scale. But in terms of an AC calibrator a fluke 5200A would not be bad with its amp 5205A can go to 1500 Vac. Which is a bit spicey. If using a meter something that needs to be taken in to account most good meters work in AC RMS scopes work in PK-PK so appropriate calculations need to be taken in to account when setting up the signal source. In terms of calibration a functioning and calibrated TG501, PG506, and SG503 will cover 99% of the scopes up to 100 Mhz. Over that will need "exotic" signal sources tunnel diode pulsers and such. I will admit I have seen the bottom of that rabbit hole it is kind of on the deep side.

Re: Calibrate the time base, or horizontal amplifier?
No need to tweak the pots!! If you just repaired the HV supply this would only effect brightness in the scope it should not really mess with the time base at all or vert amp at all. Now this goes with out saying that adjusting the reference in the power supply with cause the need for a FULL recalibration / adjustment of the scope. This can be a very deep rabbit hole. I have made a few videos on You Tube about this topic. Mainly the 7000 scopes. I am currently working on a 400 series. I can post a link if there is any interest. Remember on a 400 series spec is 3%. Not sure what it is on a 5000 but it might still be "in spec"
The type 184 time base crystal is not the most accurate thing on the planet. The type 184 or TG501 would be around the time frame for a 5000 series scope. I have only seen one of the older time base unit ever. So they are even more rare. However The reference crystal in the time base 184 has about a 50 Hz swing on 10 Mhz. +25 to -25 Hz. This is mainly caused by the ovenized crystal heating and cooling as the oven is cycling. (REALLY annoying to adjust.) The tg501 is not near as bad to adjust.
If I can be of help let me know.

Re: TDS5054B all LEDs lit, blank screen
" It does look like a nice scope, if you like the fly-by-wire instruments."
It's not as easy to operate as a Siglent or Tektronix TDS3000 series. It
does have a very nice display. Even though it's Windows 2000, I've been
able to get it to see my network server so that screenshots can be saved to
a share folder to be used in a word document on my computer. It is very
fast operation, 500MHz, 5GS/S. If it was a little more intuitive, I may
have had it certified to use with calibrations I do and worked it into some
of my utility software. Right now, it impresses the heck of people seeing
it on the repair bench running. For what I use it for on the repair bench,
a cheap Siglent would work - lol. I do want to work it into my utility
software sometime. With fast 400volt pulses, it matches my TDS3054 almost
exactly voltage, Rise Time and Pulse Width. Some scope can not even match
themselves between channels.
I don't think Tek's OpenChoise software works with it for screen shots and
setup uploads. I don't know that Tek has a utility for it. If you are
looking for a more easily usable/capable scope, I can highly recommend the
TDS3000 series. I prefer the Pre-C versions of them. The TDS3000 s are so
easy just to twist knobs and use. Openchoice works well with them and they
are easy to control and get data from using VISA commands via GPIB or
NETWORK interface. The TDS5054B just has that cool factor and can make you
feel smart when you finally figure out how to tell it you are using a 100:1
probe (LOL) or just when you use it for that matter - heh heh.
I forget what I paid for them (Okay I found out $900 for one with four
brand new P5050 Scope Probes, and $540 for one with four used scope
probes). Both worked fine when I got them, but they are huge for a digital
scope.
So in summary: The cool factor is off the scale -lol, Ease of Use, below
average

good point.
i'm glad dennis is doing ok...here are some recent anecdotes to lighten the thread:
years ago i was communicating with someone 3000 miles away and he sent me an email that just stopped mid sentence. i replied and got no answer.
he was advanced in years (a common condition here) and i had visions of him having an attack while composing and hitting "send" as a cry for help. i only knew him virtually so i had to hunt down the details and called the police for a wellness check. they were not very helpful in florida and were taking their time. i eventually got a reply from him (he accidentally hit "send" prematurely) hours later so i called police and called off wellness check.
it is an option to keep in mind though.
another: a neighbor called the police for a wellness check on me when i did not put out my garbage a day earlier. another neighbor saw cops looking in windows and
told them i was unreachable at the coast for a few days. i have the calling neighbor on my whereabouts update list now :-)
he did have some reason to be concerned, however. just previously i confronted a burglar and knives and gunfire ensued. he is currently in prison. so much for lightening it up. :-(

Nicolas,
Yes, you will need to unsolder the leads of the parts. Only one end is necessary while bending the part up. That way you can easily tell where it goes back. The hardware to remove the cans will be easily reached. If you want to replace any of the resistors while one end is up, that is up to you.

Re: FTAGH: Free to a good home: 465/475 scopes
I collect older Tube radios. The absolute best (and worst) packing jobs I have seen are in the packing of these heavy boat-anchors. The best packaging was for an absolutely pristine National HRO-5 receiver. The guy who sold it to me (who was selling it on behalf of a silent key's estate sale) did so under the priviso that the packaging would cost me $100 in addition to the cost of the receiver. One of the best $100 I ever spent. Everything was wrapped excessively, protected and came through with nary a scratch. And then there was the guy who couldn't even pack a ceramic wafer switch properly and it broke in the shipping. I still shake my head about that.
Thank You, Gordon
