Re: P6201 FET Probe, 10X divider compensation question
Hi Sean,
There's nothing wrong with your P6201.Two recommendations:
1. Put the 2465B input at 1 MOhm DC or 50 Ohm DC, *not AC*. Use the P6201's External Terminator setting if the latter and in both

P6201 FET Probe, 10X divider compensation question
Hi all,
So a while back I had the good fortune to find a brand-new, never used P6201 probe and accessories. The probe by itself is of course rated to 900 MHz, 100 Kohm, 3 pF. It comes with a slip on

Re: Scope-Mobile Cart Model 3 Disassemble
Hi Edward,
John has the right idea. I just think you can never have enough tools with
you.
Along those lines I would modify John's list slightly as follows:
Open end wrench SET (inch)

Re: Absurdly simple way to get contact cleaner into some Tek pots
Hi,
You could search for "pot cleaning cap".
They are commonly used for cleaning pots on guitars.
There are variations on eBay.
I have even seen people use threaded rod unions for the same

Re: Absurdly simple way to get contact cleaner into some Tek pots
Does anyone remember the day of TV repair (when TVs could be repaired) where General Cement (GC) I believe had a neat tool for cleaning & lubing pots from the front panel. It was sort of a hypodermic

Re: Absurdly simple way to get contact cleaner into some Tek pots
Back in 2001 I had a tender experience with my 475's modpots.
At that time I was a novice... If you promise not to laugh too much.. here is the link to the surgery

Re: 475A : excessive jitter on delayed sweep
Tektronix tended to have a square pad on circuit boards on the positive side for the capacitors... also square pad on banded end of diodes...

Re: Tek 1480C waveform monitor vs oscope
I do see it has an external X drive input, five volts for full horizontal sweep. It may have some redeeming qualities if not only for NTSC video. Of course regular X-Y displays are also dirt cheap

Re: Tek 1480C waveform monitor vs oscope
Can it be configured to be used as an X-Y display? I use an old 604 along with my HP generators as a display for sweeping along with a cheap AD606 log detector.

Re: 576 shaft repair
The advantage of my heat shrink solution is it is non-conductive. The two ends of the shaft don't meet inside the heat shrink because the original broken flexible coupler prevented them from doing

Re: 576 shaft repair
IIRC some flexible couplers in the 576 have the be insulating up to the full voltage output of the 576.
I know that because I needed to replace one and luckily Hakan Hintze had one on stock.
