Roy, thank you for the information I appreciate it 73 Richard W4MCD

I've seen bad capacitors in the Low Voltage Power Supply cause a slow startup. I would say that's usually the main cause especially in this model since it will not have the surface mount capacitor

Hello, on my bench: LeCroy 9354AM as main scope, Danaher TDS754D as second. IMHO, the TDS754_D_ is the best of the old TDS gaggle. Unlike the A / B / C, it has intensity grading in the DPO view.

I’m getting ready to purchase this scope from eBay. The add says it’s slow to startup and assumes it has problems. I won’t know until I get it tomorrow or in a few days if it’s the delayed

I'd say 1/4 to 1/2 watt with the provisions that the original (given the date) would be 1/2 watt.  Considering that you're shorting plate leads together (or the equivalent in a later scope of

I have a TDS694C that works perfectly in every way as far as I can tell, however under calibration, the signal path check reads fail. Is there anything to do for that? Jerry yahoo.com@groups.io>

I recently pulled the fan motor and driver board out of my 2465 because I couldn't find a replacement collet that holds the fan on the shaft. I replaced it with a 12V low profile computer fan and

I'm looking for some good 500MHz probes I have available some 100MHz probes.

After replacing all filter caps in power supply, supply ripple is below spec on all voltage's, normal 1V @ 50 ohm output Markers are all working. But 25V @ 1K ohm Marker Amplifier is only working up

Hi Jan, thank you. I found some on eBay. They are tiny, you can pull the from the sockets and mail them to people cheaply. I have some coming, save your diodes for emergencies. thank you,

Also, search for Jim Williams and his design books, this is very good reading! Göran
