   Judging by the inspection tag, that uber-rare Tek 549 storage CRT was made about the same time I was.  :-DD

Thanks for sharing your addiction to vintage Tek gear with the rest of us.  :-+

I just found this thread yesterday. Such beautiful equipment!  :-+

My first scope was a Tek 544 with a differential (type W?) plugin. I got it in a trade... For a printer selection switch.

At work, we had a couple Tek 2215 (I think) and some HP scopes. I hated the HP scopes, the triggers were bad. The boss said it was okay for me to bring in the 544, and it worked well, a pleasure to use.

A few years later, I got a 465M and then a 2465. The 544 was big and heavy, but I still have good memories with my first scope.

Thank you for all the nice pictures!
Currently developing STM8. Past includes 6809, Z80, 8086, PIC, MIPS, PNX1302, and some 8748 and 6805.

Restoration:    ^-^

When a tube Tek want to sniff UHF frequencys, give him this, it`s Tek voodoo from the old time.

I wish I kept RM15 from way back when....

I have lots of scopes but none made with tubes.  I guess they are "collector" items now that prices have gone up quite a bit.  I don't seem them much in wild anymore.  I would like to have ONE just for memory.

the bad side is, that some "audiophools" made parting out lists of the tubes what are plugged in all the fine scopes.
They buy instruments only for salvaging tubes what they use to build some painful audio amplifiers from them..
People who care and collect Tek Oldies will never give a scope to one of them. So the offers are mostly inside of the collectors communitys.

RM15 is the rackmount version of Tek 515A. You need exactly this instrument or any warm Tek?
If any, it`s allowed that the Tek is big and heavy like a 535A? It have to be in working order or for restoration?
Send me pm with email adress and your location area, I will ask for a nice glowing Tek.
and take a look in som american craigh lists, there are oftenly scope oldies also

That works both ways. There would be no tubes in production for repairing old equipment if it wasn't for audiophools and guitar amps.

Martin.M

Thank you.  For some reasons, I cannot send you a PM.  Click on PM button and it goes right back to the forum itself. 
My email is tkamiya9[at]yahoo.com.  Working sample is better but I am able to repair.  RM15 would be nice but any tube tek will be nice, too. 
I'm not really choosy. 

My intention is to restore it and display it like you do, as well as occasionally use it.  So ones that will clean up well would be nice.

How do you clean them SO WELL?

On one page, I see tooth paste in background and internals looking like it has been shampooed.  I love scopes and restoring them.  I can wash the outside but for inside, I only wipe.  But apparently, you do so much more.  Do you have blog or anything that I can learn from?

when we have found the Tek for you (this will be no long time  :)  )  you get a full support to restorate that, including a video how to wash inside

the website is here: www.wellenkino.de

One of your admirers sent me over here because I am considering buying a pile of 500 series oscilloscopes to save them from the dump. What excellent work you do! Thanks for posting all this here for people like me.

I bought a Tek 545B about a year ago with very low mileage on it as the previous told me it was his spare scope at work and indeed it was in absolute mint condition and no one worked on it before. I cleaned her out of all the dust and shes working beautifully! It came with the "normal" CA Type plugin and it works perfect!
Recently I bought a late model 1A1 Type plugin (In very good and clean condition and uses fets, transistors and 2 nuvistors). It shows both traces just fine but I cannot adjust the traces of both channels higher than the middle of the CRT, so in other words the middle is the highest the trace would go with the vertical pot turned all the way, it goes off screen when I turn it the other way.
I guess its way out of alignment?... or maybe just pot that needs adjustment in the plugin itself...

Any advice would be appreciated.

Jacques

This is a result while restorating a hungary made function generator. (Classic Tek 556 in XY Mode at beam 1)  :)
