I have driven forklifts and worked in a workbasket from one. That time, the idiot driver who was assigned to the job kept disappearing. It ran out of propane while I was working near the roof, running

For those that have a 485, look at the S/N to see if it is in the lower range. At one point it was changed to protect the round IC from pluses from the relay coil when switching from 50 ohm to 1meg

Barry, See if having the A/B intensity turned up and the crt bias up (more negative at the grid) helps. If your S/N is <210000, check Q320, Q322, Q420 and Q422. These are in the two heatsinks on the

No disrespect taken :) Looking at the circuit diagrams, the 485 has two separate attenuators, one 1Mohm and one 50ohm. A relay connects the BNC input to the relevant attenuator. Overload causes the

Mark, Intensity settings for normal traces are about right. The main intensity is somewhere near mid-range and the A/B intensity controls are in the 9:00 to 12:00 range (or less). I'm using a 7B53A

Barry, It sounds like the time base you are using is the source of the delayed sweep. Some have an intensity control for the delayed sweep. A 7B92A is an example. The 7704A has two main intensity

The delayed sweep intensity is way too bright in my 7704A. If I understand it correctly, a time-base sends a signal to the mainframe to indicate the delayed sweep is active and the mainframe knows to

Jean-Paul, I have already lucked out on a 2465 in January of this year, which cost slightly less than this 485 ($120 before shipping). I'm not really interested in the 2465A or 2465B, both because

Tom, no disrespect intended, but I'm looking directly at my 2465, and it has five input coupling positions for channels 1 and 2, labeled in order: 1MΩ AC, 1MΩ Gnd, 1MΩ DC, 1MΩ Gnd, and 50Ω DC

Dear Jeff the trigger difference is the least of the considerations Beware the 485 are very old, notice the small gray knobs are deteriorated. The ebay lot has total with shipping $225 minimum, and

On 485, A Ext trig view is the little button at left end of vert mode switches.

The 485 has two separate inputs: 50ohm and 1Mohm//20pF. The 24x5 have 1Mohm//15pF inputs, and you can add a 50ohm resistor to make that 50ohm//15pF. By and large, my preference is for two "proper"

I’ve been to quite a few warehouses to pick up stuff I had delivered by freight. It’s a lot cheaper to pick it up compared with home delivery since they need to dispatch a truck with a lift gate

Dear Tom, Michael and Mark, Thank you very much for your extensive answers. I will attempt to diagnose / repair the TEK475 in the next few weeks and will surely report back on the

I'm trying to convince myself not to bid on this 485 (https://www.ebay.com/itm/393631311648) which has no bids, mostly because I don't have the cash, but also because I already have a 2465 that I am

That sounds like a Drew Carey show episode where Oswald smashed the scanner in shipping while playing on a forklift.

My last UPS delivery arrived as an empty, torn box with tire tracks on it. The Ebay seller won't even reply to me, so I'm going to ask for a refund from Ebay or Paypal. A UPS delivery before that was

I reuse boxes all the time, and have a huge selection, because even though most of what I ship goes in the flat rate boxes, some items don't.  I always either strip off old labels or black them out,

I don't have any timeframe in mind, but the machine shop predicted a lead time of 5-6 weeks. They must be busy. I don't plan to place an order for these until I've got enough commitments to get me

Blame it on me: I wasn't doing a proper job of searching Mouser. Not even sure what I did to get only two results. Using Mark Vincent's search as a start point I found the variety of Vishay axial
