TES and TEA are simply two facets of a similar condition. You are in the right place, just keep on keeping on. But do try to up the ante from Chinesium lathes..
The Grizzly minis have a good rep (at least the older ones that still had all-metal gearsets) for being the right mix of inexpensive vs cheaply made. Of course, that has driven the price up to a point where you'll usually be wishing for something a little more capable, unless you can get a steal on one from someone who doesn't know what they are.

So... your dog is what... hidden
behind the mini-sasquatch stalking across the living room carpet...?

Did some work on the 6206b this morning. Checked out caps - all good. Calibrated and destickered half of the front. Other half still to go. Annoyed about the scratches from the previous idiot owner who used a screwdriver to get a cal label off.
Ok so I spent the afternoon being bad patient #1 and had a look at the 8060A again. It hurt but it was worth it. Firstly the meter was dead again. Hmm. So I replaced the battery clip on it which had been yanked off by the previous owner leaving bare wires. This took 40 bloody minutes including finding all the Metcal bits I'd packed away. Fired it up again, a lot of nope again. After doing a full brush over and inspection the elastomere strip looked like the culprit so I took the display assembly off and cleaned the board and both edges of it. Reassembled it and bam, it works perfectly, at least on DC, ohms, continuity etc. I haven't tested AC yet (waiting for FG to arrive).
Reassembled it and we're good. I like the continuity on this. Top notch!
Not content with stopping here, I know these are prone to leaking and destructive electrolytic capacitors so once my arm is better it's getting recapped and scrubbed to give it hopefully a couple of decades extra.
Total spend so far:
Meter - £18
PP3 clip - £0.54
Capacitors - £3 (incoming)
Edit: this came with the grey carry case and some TL75 style probes. I will clean them up as well later. I think the probe tips have had it so they might get binned. I've got some Pomona ones spare lying around.
So you inspired me to restore my Fluke 8060A today, which needed to be opened anyway due to the battery clip falling apart. I checked the electrolytics while I was there and they all look fine, so I didn't replace them (highly influenced by the fact that I don't have any capacitors short enough to replace them).

Looks like that the living room carpet is a dangerous enemy.

Dealing with past Gorilla activity will always be our lot in life.
That's why I always have a stock of Krylon on hand.
Whoops, I did it again, baby. Yeah!
Photo from the auction I just won now.
The verdict on this Type 3A74 Vertical plug-in.......
I managed to get 4 traces. All unstable with channel 3 being the worst. It bounces where ever it wants to. None will consistently pass a signal although I did manage to get channel 1 to pass something...and then it died. Apparently I'm going to have to dive into the attenuator switch decks and completely clean them too. Oh fun. I was hoping I wouldn't have to. But not today. Got other things to do. Into the repair cue.
finished a PC build for a fellow forum member. W7 in an ITX footprint with a Fractal Design case.
Hope he is happy with it.

I must be ill. I have nothing on my watch list at the moment. Must fix.

Take your mouse! Strike the buy button with all your hatred, and your journey towards the TEA side will be complete!
Use your obsessive feelings, boy. Let the test equipment obsession flow through you.
I can feel your obsession. Let your obsession flow, and with one single strike of the buyitnow you will complete your journey to the dark side ...

If you want proper tool envy over a lathe, take a look at Dan Gelbart's "scratch build" lathe and grinder.

I'll see your South Bend and raise you a Dan Gelbart.

So the A trace from my Type CA was doing the bouncing thing, turned out to be the switching multivibrator tube being bad. It stopped when I swapped in another 12AT7.
Tektronix TM500. Modular test gear.
Rest of 6206B cleaned up. Some permanent marker and scratches left but better for sure. Took all flipping day to do a 10 minute job

After:
Most important thing is it works properly!
@bd139, Great job on that clean up, Bloody gorilla's, they have zero respect for equipment have they

My planned tactic for working on this is to get channel 1 fully functional all the way to the Vertical output. That way I can use channel 1 as a template and a cross check while troubleshooting the other 3 channels since they are all identical.
