A note from "back in the day" ... In the 70s and early 80s, all of the motorcycle parts shops that serviced Jap bikes had a cabinet of allen head screws that covered the full range of ?the most

Did you do the grid bias adjustment in the service manual? Tom

Thanks for the detailed investigation. I'm not really any further than before. Some of my screws do not fit a new phillips driver well, others fit perfectly. Not all of those which don't fit well have

The maximum intensity of the trace on my 2215 is very low. It makes impossible to use the delayed time base. I have checked the power supplies, 2KV and 8 KV are OK. Does somebody have some idea for

I heard back from another retired Honda person on this question about the JIS vs. ISO vs. Phillips question. Apparently the Honda screws with the single dot on them are the ones that have the newer

Hi David, It's difficult to say which LV regulator is responsible, assuming that it's not a combination of effects. You might be right about those -50V and -15V regulators. Specifically the -15V

It's right under the "REFERENCE LEVEL" label. See photo: http://www.slack.com/images/TE/Tek494P.jpg

Oh man I don't need another scope, yet I'm driving up to Seattle tomorrow to pick up one. It's not one of these :-( Bill Higdon

Can you get a dot on screen in X-Y mode ? This mode is a little tricky to set up; do you have the manual ? HankC, Boston

Hi, Does someone have a junk 7704A that powers up okay? One with a bad CRT would work. I cannot pay much more than shipping to Central Texas, 76501(Temple area). Please respond off list. Jerry

And to add to my misery, the Om describes a procedure which is initiated by pressing <SHIFT> <CAL> I have searched high and low but can not find the <CAL> button. This is driving up the wall and over

on bit That sounds about right. It depends on the collector base capacitance, but you can end up with "looping" where this capacitance has a significant effect, particularly with medium to high power

One other issue is that when I try and set the VOLTS/STEP ADJ according to the procedure on page 5-4 of the manual, I can only get 2 traces per major division with the pot turned all the way

I've checked and replaced a few caps in the -150V, 100V, and 300V supplies in my Tek 575. Now these supplies are all in spec for voltage and ripple. One cap seems to have an elevated ESR, so I'll

If you mean the PCB assembly to scope cross-reference, there are at least two versions, one of which should be in Tekscope's files or one of the other Tek repositories. -Dave

Of the three different readout boards that I now know of now, the 7844 uses the common one so it will be the easiest to find as it is on the less expensive 7000 series mainframes. I am surprised there

Thanks for all the info. I have a couple of 7844s in need of repair, so may end up with one working unit, and a display board donor...? Michael

The capacitors should be more important than the sense lines. They provide part of each regulator's frequency and phase compensation. I would be suspicious if not hooking up the sense lines has an
