Thanks Dave. I have downloaded every manual I can find, and the Tek troubleshooting your oscilloscope guide as well. Spent the better part of yesterday going over it. I can get a trigger light on ch1

Dan, Thank you for your well presented message. IMHO this does relate for the reasons you've stated. I am currently setting up my financial infrastructure to sell, including on eBay. I'm afraid I'll

As I understand it, eBay will no longer provide your account information to the buyer at all. Instead the buyer pays eBay, which acts as an escrow, and will eventually pay you (or not). The number of

I don’t necessarily see this as a problem. Over here in France, and I think it’s the same within the EU, once the money is in your bank account, there is no way for anyone but yourself to withdraw

I realized that I didn’t see any CRT filament/heater glow in this newer 7603 so I put the working PSU in the other 7603 and in that scope I see the CRT is glowing. I can see a dot on the CRT screen

Ebay sold off PayPal *years* ago so I'm not a bit surprised to see that they've done this. Paypal also (at least used to) required that sellers link their PP accounts to a bank account so I don't see

Brokerage accounts such as Fidelity and e-Trade have cash management features with check writing. For some (I checked e-Trade), no minimum balance is required to open an account. Fees are generally

Hi folks, this is OFF TOPIC because it's about e-bay, but on the other hand, with the exception of my older gear, it's just about the only way I get *any* Tek or HP gear these days.? So, with

I agree with Stephen. Use enough iron! If you use too small of an iron you'll have to hold it on the board for too long while you wait for the solder to heat up enough and melt and there's a good

Thanks everyone!! Doesn’t look so formidable a job now. Bill

Hi Michael, Last night my curiosity got the better of me and I searched for and found the DM501 schematics. BTW, the Tek Wiki's DM501 (not DM501A) manual is incomplete, and I found one with complete,

If you will be considering one of the 224x line of scopes (2245/2245A, 2246/2246A, 2247A, and 2252A), I'd aim for the 2247A model, it has a couple of very useful additional counter/timer features over

I have used this seller's products for years. They are excellent. Also note that he has added a larger via to allow the use of "snap in" capacitors. This opens up another group of capacitors for your

Hi Bill, I slip a single ended hacksaw blade just under the cap, and saw off the lugs to remove the cap.? After that, very little heat is needed to remove the nubs from the board. Make sure you do
