Re: My 453 is tough to twist
Take the knob off and try dripping it down the shaft. A little at a time and let it soak in for a while. Tom

I'm looking for a recommendation on what to use as a replacement for tek's 152-0242-00 diode as used in the dc restore circuit of the 485. Initial symptoms with this scope were no visible beam, even

Re: 475 Triggering Issue -- Will recent 468 Triggering Issue Thread Help Me?
Though on that 300 mV, actually if CR566 was open, there should be no more than a few tens of mV... Mumble.... I'm scratching my head now.... Max

Re: 475 Triggering Issue -- Will recent 468 Triggering Issue Thread Help Me?
Yes Albert, I've taken into account that but, since the Stan's scope has only a mere 4 MHz bandwidth, I cannot be sure if he can see some strange oscillations on CR566... Tek recommends a scope with

Re: 475 Triggering Issue -- Will recent 468 Triggering Issue Thread Help Me?
Could CR566 start to oscillate for some reason? If CR566 is shortcut or passive restive or open then the 300 mV signal at CR566 can't be explained. When the 6 mA supplied to CR566 after the switch of

That switch wants to swim in electronic spray with some oil components in it. You know that crap that makes your fingers slippery. ;) The rod is probably heavily in love with some old, surrounding,

The problem with it is that the diagram showing the pinout on the last page is ambiguous about it being the top or bottom view. As far as I know, they are always the bottom view. -=-=-=- The dashed

Re: pinout for mosfet to-3
The data sheet reference clearly shows the pins numbered viewing from the bottom (page 7). The two concentric dotted-line circles indicate that the "cover" is on the other side of the part as depicted

Hi , the drawing is not ambiguous , the two round dashed lines (the round dome over the case) mean that are not directly visible, so the view is from bottom . Laszlo 2013/1/28 David
