Actually every panel owns all the necessary LEDs, you can even see them blinking through the panel at power on :) The difference is that for the TV panel there is more labelling ("Line" trigger...),

IIRC there are also front panel differences that go with the TV trigger option, there's an extra button and some labelling differences.

Anyone who has that ASIC has, or at least had, the board it was robbed from... I truly doubt there are any NOS CTT ASICs anywhere in the world. And, $250 buys you a couple weeks of lunches and

Hi, I'm not sure you have the right number.  Not 261.  The looping cap is C632 and number is 281-0197-01 made by E. F. Johnson. Carl Hallberg (W9CJH)

BTW I did not see neon, DS274, (DS271+DS272+DS273 in series) lit.

Hello David: Thank you for your prompt reply. I will wait overnight and try again tomorrow. It looked like e-beam was pushed twice as much in each direction. This could happen if electrons move

If you switch it off and allow it to cool down for (say) a few hours or overnight, does it work again for a while? I'm thinking this might be one of the problematic epoxy potted HT

BTW +-30V. 200V and 5V all were within spec. Haven't checked their ripple content yet.

Hello: Today I dig out my 5116+5D10 to display signal from FG501 and FG501A. I used "channal addition" to display added signal from two oscillators tuned to nearly 7kHz sine wave. At equal amplitude

Hello Chuck, You're right, there is one ASIC but I can find it on ebay. Actually the main problem is the crystal, its frequency is 13.10669MHz, I can't find one. I'd love to buy another 2465B but

Bill, Let me check this weekend to see what boards I have. I think I have a 7603 that may have that board. I will let you know. John aol.com@groups.io> wrote:

Hi everyone, For strain-relieve, I've consider it but: * this will make the PCB bigger however that's not so much of a problem; * the solder sides will be at the back, whereas front side, the

Steve, I don't think I have that scope any longer, but I do have other tek scopes for parts. I know that a 7603 and a 7404 for parts. 73 - Jihn

Just checked the 2215 sm, it should have 6 screws total removed. You pop the shield out by pulling upwards on the right rear corner of the shield. There are some little slots in the chasis that the

You missed the custom ASICs that do all the counter timer work. It would be far cheaper to buy another 2465B that has the options you want. -Chuck Harris pbapp41@... wrote:

Hello all, I own a Tek 2465B and I like it a lot :) I started digging the web to find options boards but after having bought a TV option 05 I discovered it was the same board as the CTT, but only
