Whenever tackling a new/difficult piece, always finish off with a bit of fun nonsense - so yes, chopsticks will do the trick. That way you go away with a pleasant subconscious memory. It's like giving a dog a reward after a trick (but you don't have to do the tail wagging bit).

Just to be clear, I'm simply making a high-resistance probe here, and not adding a voltage divider, as suggested here? Their justification for a potential divider setup is safety, but at the voltages you are working and with the series resistance this really isn't a problem. Absolute worst case a 9...

...every note needs to shine like a diamond and should be played with and exploited ... hang on to a note for a few milliseconds, cut it back a bit perhaps, play with tempo, rubatos, rallentandos, accelerandos and so on. And dynamics. Well, yes. As long as that is interpreted as "every note ma...

In a sense this is (potentially) good news. It points to a bad connection somewhere rather than a faulty component.

I suggest you make a very close examination of PCBs with good light and a magnifier, particularly in the vicinity of plugs and sockets. Check all connectors as well of course.

Wow! Almost twice the grid bias supply. That would certainly make things interesting. It would suggest virtually no beam current. If it weren't for the fact that the -1kV line is low I'd say it was R121 open circuit (worth checking anyway). I would however, want to make an alternative check on that ...

Has it always done that? Ha! Beaten to it :) Lots of amps go a bit 'strange' as the power dies away, but ones with relays in the outputs hide that from you. Does yours have relays (as far as you know). If it's not something new it's nothing to worry about. If it is, then keep a check on the situatio...

What's 'serialism'?

Hi Will, There are quite a few lowish voltages marked and it might be an idea to measure those and work out some current flows? This might give an idea as to whether you are looking for a short/leak or an OC somewhere? The old guys at the British antique radio soc' might be able to shed some light....

Very much inclined to agree with sonarbell. If that has gone seriously leaky it'll load the transformer enough to drag everything right down. I'm also a bit surprised at C78 & C79. They are rated at 1kV and running at 1kV. I would have expected to see 1.5kV caps there. C75 & C81 should also ...

I seem to remember reading that any comment on someone's grammar or spelling is destined to contain at least one such error itself. Therefore too safe embarrassment Ive insured there are sufficient off both hear two justify my comment's. P.S. I'm, not saying it's the case with the OP but I also reme...

Interesting. What do the numbers on the vertical scale represent? BPM? %? Something obvious I didn't think of?

If poking a few watts down there can I mention fuses? Dave. Yes indeed! Personally I wouldn't mix mains voltages with any other cable, and make sure you're using proper BS {whatever}. Cheap cables saying 240V is not necessarily suitable. Then again, I wouldn't mix signal (even balanced) with contro...

Moog don't develop for the PC, Mac or Android where piracy is rife, yet they released an app for the iPad very early on. I was under the impression the reason most people don't develop audio app's for droid was that the audio capabilities out of the box were a bit of a dog latency wise and it wasn'...

I just hope they weren't using side chaining

I thought the CPU this uses is obsolete. Am I wrong? {it's near the end of the month so I can use up my remaining quota of errors}

Very interesting Folderol. So you "unbalanced" the opamp rails to achieve asymmetry about the zero line - is that right? That's right. It doesn't have quite the same effect as the transistor /resistor output does, but in engineers terms I'd say "Close Enough". What does that do ...

So what you need to do is sample it and then re-pitch by re-sampling and looping for longer notes and then combine for harmonics and then record yourself hitting piano strings and lampshades and build a DIY reverb tank using a drum and some tape heads and and and And wait for a commission for a new...

Oh dear.
... and we had been doing so well
