I am having a case of TES http://www.mini-lathe.com/Mini_lathe/Start/start.htm#tesTES 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..

Sorry for a completely off topic post but my daughter took this photo of our dog Griffin, in full flight.

Geez I just wish I had half that space for my lab Look what you can achieve if you don’t get married! I just watched that video. I feel so inadequate. Very surprised that there are reels of SMD, think he only do tubes. Is it a basement or the floor will collapse Its a basement, and he does a lot of SMD work, all of his new inventions are done with SMD, its a great channel, and he takes a lot of care to fully explain what he is doing.

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 - £18PP3 clip - £0.54Capacitors - £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.
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. (Attachment Link)
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.

Into the repair cue.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.
