disregard the "??" on the earlier note. this seesm to be something that thunderbird is doing to me. Chuck really did calibrate it and it runs very nicely now.

Chuck Harris in Maryland re-capped the PS, did some other repairs, and replaced the NVRAM with an FRAM, and calibrated?? one of my 2445b's all for a very reasonable price.?? Shipping from Florida

Kevin, I am *assuming* that a digest collects posts over a moderate time period and those messages mage up that digest. So if your post and any replies happen on that time interval, they show up on

Whoops! I made a mistake in the last sentence, it should read: 'I have had very good luck using the IRF840 MOSFET for Q9070, and with using the transistor TIP41C for _Q946_ and Q947, and I think those

Arrggghhh... see below .... DaveD eight, not four

Could be. There's a chance that you have a low-resistance condition in one of the small epoxy-dipped ceramic caps on the span attenuator board (if I recall correctly, it's been a while). They don't

While I hate to let a cat out of the bag, if you are willing to pay for it (and it does cost a monthly fee) Terapeak (now an Ebay subsidiary) DOES provide actual selling price information for BIN

The hours count is most likely since last calibration, as the calibration instructions would have you reset it. I figure this was to keep track of time since cal, more than total operating hours.

Your question of how hot the heat sink gets near the MOSFET  Q9070 made me want to check a 2235 I had worked on just enough to get it to run. This 2235 needed a lot of new power supply parts

Wrong! Final value fees DO get subtracted?? from the shipping costs that a seller charges. Even if you use Ebay to buy and print the label!

Brad, I have purchased four 7xxx 'scopes and had them shipped to me. None of them were packed well, not even remotely. The fact that they arrived intact has always surprised me. I've also purchased

Thanks. Done that, my 'scope has 4810 hours of power on, and 1160 power cycles. How do those numbers place my instrument in the average ranking ? Much used ? Not much used ? Average used ? -- /*73

Caps are on the way, but I also just discovered the 5kHz scan per division is actually scanning the same as 50kHz per division. Wonder if that is related to the cal problem? Decoding issue on a board

Details for getting that display, too much for me to type out, are in Appendix A of the Operator's Manual. There's details for setting the hours in the Service manual, but that's about 6 cms thick so

Not everybody is reading postings in digested format... I for one receive in my inbox each message individually... so, if I see a post and reply immediately to it, there is a big chance that the

You can choose to receive messages in a digest or individually. If you receive them individually, you get them as soon as they're posted. If you choose digest, you get them all at once at whatever

I have been on this list for a long time. It just dawned on me that there are aspects about it I don’t understand. How can there be a reply to my specific post within the same email digest that my

How can I make my 2465B display the hours count ? Are the debug commands of the firmware listed somewhere ? TNX -- /*73 Alberto I2PHD* <<< http://www.weaksignals.com >>>/

Thankyou Tom, i`ll drop him a line..................Don

@Jim Potter I should have been clearer. What I meant was that, as a competitor trying to figure out what an item sold for and to price the same or similar item, past fixed price sales are misleading.
