 My 8060a arrived today, but it needs a little help. I'll post about it in the repair section. Nothing that can't be fixed, and for under $40 shipped it's going to work out nice.

Just won a Tektronix 7613 mainframe with a timebase and amplifier plugin (missing several knobs and latch with model numbers) for under $29USD  INCLUDING SHIPPING!.  Paid $5.50 for the unit itself.  It's about 12 hours north of me and shipping via FedEx - from a seller I have experience with - so I expect to have it by the end of the week.

I guess I just lucked out!!  It started at $0.99 and there was only one other bidder who put $5.00 on it.  I put a $40.00 max bid on it before I left for work and fully expected to lose it.... but once I got home and checked on it....... POOF! Mine for $5.50!   

It's apparent that the timebase plugin is in the wrong slot which may (or may not) be the reason for the wacked out display. I have all of the replacement knobs already lying around, too.  First things first though - it's going to get a thorough cleaning, visual check, capacitor check, and component reseating before I even attempt to power it on.

Here she be.....

I have a 561a tek scope with 2 plugins 1-2a63 dif.amp and 1-53/54d dif. amp.
that could be someones for free.
pick up only in east la county or north san diego county usa.
It has been sitting on a shelf for the last 30 years dusty but 30 years ago it had a trace.
I had thought about pulling the tubes and parting it out but if some one wants it come and get it.
PM me for details.

The pull tabs are gone 
Be careful taking those out. I did use needle pliers to unlock them but it is tricky to do.

Not too tricky but don't force them out.

I got one for $50 but that included also a 5110, they were in pretty bad shape both of them but a bargain nethertheless



They did clean up ok:

Looks nice

Did you have to do anything other than clean them up?   I am already looking for some plugins - both working and also some extra cheap units for the mechanical parts.   If you have a thread for their repairs (if you did any) please link it in for me. 
Thanks for the heads up about the pull tabs... I will start looking into what the best way to remove and temporarily repair them are in case I don't have replacement pull tabs in time.

[Cubdriver]

Wow, Miguel - those cleaned up beautifully!  I have a 7603 that came in a haul I got from an estate a few months ago, but I haven't gotten a chance to dig into it yet.

The mainframe was fine, I did get new plug ins and followed the calibration. So other than the cleaning, I didn't have to do a thing on the mainframe.

Only repair I did was on an amplifier plug-in for my 7603, due to physical damage.

Pics of a simple way to unlock modules lacking the pull tabs.
Also a pic of the early metal pull tab, which would be easy to make if you can't find any.

cordless drill/screwdriver:
bosch gsr 10,8-2-li Professional, "set 2" comes with metal drills 2-8mm, wood drills 3-10mm, a 25pcs bit-set (straight, phillips, allen, torx), and a cute bag.

not something for building a house, but I hope it will be OK for small jobs in a city apartment.
didn't do much market research - the shop didn't have any Makita in stock so I went with this Bosch...

I bought this too, but with a hard case instead of a bag. I love it! Since then I added the hand held vac skin.

[Addicted2AnalogTek]

Well, it appears that I have just purchased a Tektronix 7854 mainframe for little over $100.  That in addition to the DS1054Z and new Hakko soldering station.

I suppose I will be selling my 7613 mainframe and one of my 485s. Or maybe a Tek 106 instead..

For some semi serious sound mixing. Yamaha MG10XU.

Some tools on Amazon 

[lpaseen]

I was to a junkstore here and scored a programmable rotary encoder pr1000
Not sure exactly what I going to use them for but hope i can come up with some cool project for them.

Escort EGC-2230 for about €100 delivered.



Didn't look too horrible, powered up okay, but the waveforms were all over the place - the 2MHz square wave looked like an ECG. So out with the screwdriver...



Lots of discretes, lots of solder joints to check, but hang on...



Well that don't look right! I guess the courier wasn't exactly gentle and shredded paper doesn't do as good a job as bubble-wrap. A quick soldering job later...



Square wave is still a bit janky, but I've not exactly used a terminated BNC connection and it's the upper part of the spec'd range on a 20-year-old generator...



Triangular isn't much better.



Though sine seems reasonable.



And to be fair, at lower amplitudes and slightly lower frequencies, everything's fine (and it does what I need for the current project quite handily).

The DC offset's kaput though - I turn it on at all and everything gets clipped horribly no matter the function selected.

I think I'll have to go over the board a bit more carefully and check for properly seated ICs, clean the switch contacts and that sort of thing.
Anyone happen to have a manual for the EGC-2230? I could only find the EGC-3230 online.

[AF6LJ]

Looks good, I should get a basic function generator...

[Bob F.]

By coincidence, I got that sig gen's sibling, the EGC 3230, a couple of weeks ago (also known as the KENWOOD FG-273 according to google).  I thought mine was on the blink too but didn't really care - I was half looking forward to a fixer-upper given that the service manual is available for download and it only cost 31 UK beer-tokens inc postage.  Turned out I just needed to move the DUTY knob all the way down...  Not sure why that would affect the sinewave output, but it did.  Can't find a user manual - only the service manual for free - tho even I should be able to work it out...

[MarkDennehy]

Damn, £31? I did not get a bargain

[McBryce]

Just scored a working HP 3478A is good condition for €100. In Europe that's a bargain

These two bad boys! They came in original packaging, which was falling apart and was almost 30 years old. 10 bucks each on ebay, but they are smooth as hell. Stuck a knob on one, and turning it is a pleasure. 2x320 pF and they have a 100K pot at the ends (which measures 99.49K!). Great for building transmitters and receivers (SW).
