I see that's one of those little Tek-made ones. I noticed some on my spare 576 boards recently - I didn't recall/realize they had used some of these. Since the 576 is a very low frequency application,

BTW Several people have claimed here that PayPal will not reverse the fees on a refund. This is certainly false. I've been running a business via PayPal for fifteen years. Everything gets

For others of the unwashed (myself included) thank you for not passing on a problem!! +++++++ Further: That said, I would be interested in any references to how to pull of the calibration without

I have not had good luck buying stuff from Israel. I can think of about ten items I've bought and all of them I wish I could have changed my mind. The only reason I can think why, is possibly all the

Gary, Link to where on Ebay I purchased the tunnels:

My tek 576 had a relay with open coil. I had one spare in my parts 576 that fixed the problem but would like to replace it. The relays are available on Ebay as Item 312629099480 Tektronix

Gary, I deleted the email where you posted the part number you are trying to find, but I have a few 152-0125-01, 4.7 ma. tunnels; they are replacements for 1N3717 and TD-3A, I am told. I used

Dave, While looking at diode data for Gary I noticed that your 5082-3080 part has a standard part number of 1N5767. This device is available. Greg

Gary, You might look at the Microchip/Microsemi GC4410-115-2 or UM7301B to see if they come close to what you could use. But be prepared to hand over some cash. Greg

A simple drawer plugin would be OK for a mainframe that was staying in one spot on the bench, but not so great for one that was moved around. Small parts would migrate over the drawer sides and get

A friend gave me this one saying it had never been used. It still had the little paper stuck on the CRT saying how to power it up if it had been off for over a month. But of course it did not work

Hi: Check first , my 606B also had the problems, even the small value E-Cap ! Rd Tony C 從我的iPhone傳送

I think I am remembering correctly when I say that Tektronix recommended the use of IPA (isopropyl alcohol, isopropanol, propan-2-ol) because many other cleaning agents could damage the substrate of

If anyone needs a jug for a 2465B I have one here in Kenilworth, UK. It had good intensity when I removed it from a 2430A with bad CCDs. Postage to US may be prohibitive tho' D.

Grin! The trick is knowing where to stop (bathrooms come to mind!) -Dave

Hello Dennis, Sorry for my short response - I am running a severe fever, but must keep working due to a staff shortage both in my firm and at some suppliers. I have a very ambivalent relationship to

Just a thought: if you tweak the Grid Bias setting on the side, do you see any change in intensity?

Before you give up all hope, check for very large values of ripple on the -30V and +120V supplies. The bulk smoothing capacitors can go low capacitance / high ESR with age and you get almost 100%

Always get the power supplies working first. Looks like you need to replace some electrolytics.
