Have you given the switch a good workout? Check the switch works with a continuity tester.

--- End quote ---

The schematic shows two fusible resistors but they wouldn't affect only the AC range.

Maybe it's the TRMS converter. Get your oscilloscope out and have a look at the signals on S3B and S3D (Switch 3, contacts B+D). See manual/schematic for details.

(Isn't it nice having a proper manual?)

(I apologize for the long length of this post and perhaps too much detail here. But not everyone doing this has your years of experience. Use good ESD practices.)

It'll be my first time.  :)

Digikey wants $19 shipping for $8 of caps (the joys of not living in the USA) so I'm looking at other things that probably need recapping, too. Might as well order stuff in batches.

It's also a good excuse to finally get a hot air gun. Nothing fancy - I don't sit all day doing rework or SMD PCBs.

I can't see any visible corrosion or 'spewage' in my capacitors so I figure a few more weeks won't hurt.

Edit: I think I'm going to need a bigger bottle of IPA...  :scared:
Fungus:
I like my 8060A. It's my new favorite meter. I like the way it works, I think I prefer the side switches to dials.

Here's some pics of it measuring things on my little home-made reference box. This is untweaked, exactly how it arrived from eBay.

I need to add some more voltage ranges to my box. I need something around 1V and something around 190mV to give the 8060A a proper workout.

Maybe you could start your very own "Electro Detective's Rants" thread.   8)

That's too much thunder and views to jack from the members   ;D

Then again, some of these company reps that lurk here might take note, buckle up and get into some prodding back at HQ to lift their game
and supply some TRULY ROBUST professional field tech and lab products, that customers old and new might consider worth paying big dollars for, 

if their CEOs ever get woken up, unglued and airlifted from their chairs, (take a break from strenuous line work and custom massages) to work out why they get paid too much,
and make an effort to justify it.

Someone pinch me, this dream is going nowhere fast   :-[





 

 



jh15:
Thanks, Fungus.

All the switches are solid, no scratchyness. I also did all the self tests including the switch tests. All ok according to table. Not sure how thorough that is.

I don't want to lose my chance of returning it. I wrote the seller last night asking if I could poke around inside, but haven't heard from him yet.

Further pondering of schematic tells me the cap replacement list would not be related to the trms area anyway.

The ac coupling cap on the input is unlikely to be bad.

Bummer, I thought I'd be able to use it this weekend in DB mode to work on broadcast and recording studio upgrades.
