I don't know where the "?" mark after CCD's came from... but I have removed it. -------------------------------- Chuck Harris wrote: I suppose it's worth mentioning that a 2440 cannot be safely run

Take the A5 board out of the scope, and set it on an insulating surface... a wooden work bench is fine. Ordinary, grounded, soldering and desoldering equipment is recommended. The data is saved by

I suppose it's worth mentioning that a 2440 cannot be safely run for more than 10-15 seconds with its case removed, unless you position a fan to blow a stiff breeze on the scopes CCD's? This is

Hello all: Just opened a 2467 OPT 06, 10. SN B010xxx. Works fine, call seems OK. ~3K HRs 150 cyc, Orig A1 U800, A5 thru hole I plan to recalibrate but for the moment would attempt to just swap out the

c1757 has no real voltage. looks like short on meter in circuit. so i was thinking of clipping part out and surface replacing since i dont want to spend a week trying to get the board out and possibly

BTW, does anyone offer repair services for the PG506? Mine has quit working (partially) and It is over my head to figure out the problem. I would appreciate someone who knows what they are doing to

I have 2 of Dan Meeks extenders and they work great. These are not really that expensive, considering the quality of the kits. They take about 1/2 hour to build, if you are experienced with soldering.

where can i get the chassis clips that touch the outter case ?

Hi, Does it pass the self-cal? I would do a cold start and redo the calibration. This should not take anywhere near 23-30 minutes, only maybe 1 or 2. Check first that you do not need to do any

If you search back thru this message base back thru 2016 you will find a couple people who have made extender cables for TM500's.? I think Dan Meeks and John Griessen made them. Also, there are ebay

Hello Jim: The extender costs are high, and some plugins need several connectors. I have fixed many TM500 modules by taking a 1-2-3-4 wide mainframe and removing all the covers. A 1 wide plugin in a

I believe this could be a characteristic of this instrument, I watched a video from YouTube CuriousMarc - Tektronix 577 repair and Demo. Carefully watching that video with the variable collector set

They are a modular pot that can be disassembled by removing a pair of micro torx screws from the back side, and popping off the back. Use something like DeOxit Fader Lube. -Chuck Harris

Thanks Chuck. It's the 2465, not A or B. Can these pots be cleaned like a traditional pot, or are they sealed?

My thanks and I got some good encouragement and experience from your post - Thanks. Bill

No, I was not using an isolation transformer (I don’t have one) and yes I was measuring between cap and chassis. I will look into getting a transformer before testing across c2202 or doing other

Hi Bill, No... There was nothing that I wrote that I think is wrong. It was a matter of timing.? I hadn't read all of the other replies, especially the one where you found the attenuator pin issue! I

Hello Again, I went back to the circuit around Q1306 and Q1308 this evening. The resistors are all within specs. C1305 was pulled and checked. It is also fine. C1304 is good and so is C1302. By the
