Oh YES. Vinyl arrived today - gob smackingly good. An unremittingly bleak picture of modern life in Waters' glorious prose, with such superb one liners: "Picture a leader with no fucking brains" and in another song "And every time a nincompoop becomes the President"

Hey it is late, and a bottle of wine has gone down. Covfefe.

Woah - how did I miss this? Welcome back cat whisperer - belated happy birthday!

Hate to suggest this - dry solder joint? Through-hole plating on one component flakey? Resistor with flakey end-cap? I absolutely detest intermittents. Back in the day (late 70's) I was using a Tektronix 7912 transient digitizer to record fast laser pulses. This was in the days that you strapped a polaroid camera to the faceplate and photographed the trace. Except the readout of sensitivity and sweep speed would jump up and down just when you clicked the shutter. To cut a long story short, as part of the readout insertion circuity, the signal went through a plated hole from the top layer to an internal layer on a 6-layer board - and that was an intermittent contact - the plating had not taken to the internal trace. I flooded the damned thing with solder in the hope that the flux would help make enough of a solder bridge to cure the problem. It did - or enough to get me through the measurements with no further readout-jumping incident. That took quite a bit of detective work and quite some time, and Tek's excellent manual, to cure.

Just watch for the barbed wire!

Got the vinyl 50th anniversary Sgt Pepper delivered today. Bloody awesome.

Don't forget now!

^ Not available in the UK.

Happy birthday - and hope to see you back soon!

My corns are definitely popping

I don't know about anything other than booze in Dubai, but if anything else goes down it has to be absolutely under the radar. Anyone getting caught is going to have a seriously bad day.

Indeed - I was invited when in Dubai to the home of a guy who used to be Secretary General of OPEC. Out came the whiskey. I was pretty shocked, until I clocked that if you are influential you get access to all sorts of prohibited stuff. Provided you are discreet of course.

RIP John Noakes. He is probably only known to Brits of a certain age, but he was one of the presenters on a Children's magazine programme called Blue Peter in the 60's and 70's, and was a must watch (it is still running!) Noakes was known as a high risk guy - on one show he climbed Nelson's column with the pigeon shit cleaning team. Up a set of wooden ladders, including an overhang at the plinth. With no safety gear, harness, hard had etc - and wearing the 70's fashion statement of bell bottomed trousers. Died at age 83 after a battle with Alzheimers. http://www.bbc.co.uk/news/entertainment-arts-40083025 And this has the Nelson's Column sequence.

I have the original mono 1967 first pressing. Bought new when I was but a pre-pubescent lad.

Now that shows solidarity with the injured big time. Particularly since the Queen is now 91 years old. Respect. She did not see, and rightly so, those injured with life changing injuries - massive facial trauma, limb amputations and on life support.

I cut my whiskey teeth on Bushmills Black Bush when I was about 18. http://www.bushmills.com/whiskey/ Must buy a bottle and see what it is like in retrospect. But that Redbreast cask strength was a great shout - well chosen.

Lots of news on the radio about Roger Moore. He was always self deprecating about his abilities - along the lines of "I was lucky. I'm not the best actor, but was lucky enough to be good looking, and got spotted by Hollywood, and so got the romantic movie roles". Always came across as a nice guy, and really not the usual luvvie thesp.

Manchester bomber was the 22 year old son of Libyan refugees. Salman Abedi.

Who can possibly forget the the secret keypad that needed five numbers, and which played the tune from Close Encounters? No Bond before or since has been played for laughs the way Moore did.

RIP Roger Moore, age 89. I recall him saying quite recently that his acting involved "First raising this eyebrow, then raising the other one".

Have a truly great day Brent!

Another possibility (which alas involves a trace cut to try) is to add grid stoppers on the input tubes - about 1k.

Well something is clearly different between his first T2 to his second. Any idea what he should check to find out?

OK - frequency has gone down (not too surprising since C has gone up) and amplitude has gone up a bit. The issue in my mind is that a gross instability around the feedback loop usually builds up to a rail to rail oscillation, whereas this is almost sinusoidal and well below the peak-peak of what this amp is capable of. Next line of attack - cascode circuits are notorious for self oscillation, which would probably limit the amplitude. So first look for differences in layout from one channel to the other - particularly (a) the position of R86 and R87 to U1 and U2. The position and routing of R6/C2 and R5/C1/R92. If there are differences between L and R - and a few cm of track might be enough - they might be significant enough to cause this. Not saying this is the cause - just working the options.
