I would say upgrade to a proper +/- PSU first. Those charge pump devices are very limited and usually have no voltage regulation.

Next isolate the power sections with small series resistors and caps to ground (say 220R & 100u)

Wow! It's been some time since the cleaners were in. Look at all the dust round here :frown: Anyway, I've made two changes to the amp. The first is replacing the mains transformer with a torroidal one. This gives a slightly higher supply voltage and a slighty improved hum level - you need to get ...

I can't advise, but I'm a bit surprised you've had no answers.

Sounds rather like crosstalk through the supplies (or ground). Check they are well filtered, and the ground is good.

Doh! Thanks Andy
That is so unbelievably obvious. What's more I've done exactly that in the past!
I shall go and stand in the corner facing the wall

Thanks for your comments Mike. I think the problem is I'm sort of telling two parallel stories here (never tried that before). Easy with a film and not too hard with text, but musically? I'll try using more of the first part, and then maybe during the fade down try slowly collapsing it to mono and ...

I really don't understand why people seem to have such difficulty. Maybe there's stuff that I learned a long time ago and now forget that I ever had to learn it. However, as a start: Install debian/ubuntu/mint etc. using synaptic, install qjackctl and yoshimi plug in class complient usb keyboard ...

I have a story (The tribes) I 've developed over a long time, and have been setting it to music. The first two parts (which I've previously placed here) have worked pretty well, but the third part is really causing me problems. There is a link here with the tracks, and the story itself attached to ...

Do something completely different for a while, but keep listening to plenty of different syles of music.

Yes James, Master has agreed to ship them the PH-1200K free of charge to see if that will work for them. Heat Gun I'll keep checking with them to see how successful this is. In the meantime, the folks in Curacao have found a heat gun locally that they are trying and claim it's rated for 50hz/60hz ...

I would say that depends on a great many factors. Why were they abandoned: Not enough musical skill at that time? Creative block? Rubbish Kit? Crap idea? Then again do they have: Sentimental value? A watershed moment? There are a number of very old compositions of mine I've resurected and been very ...

Software installation is one of those things that is just different on Linux. Most distros have an integrated system for installing apps. Usually, software installation on Linux is more like installing an app on a cell phone. I don't use a cell-phone that can download crapps, someone phones me, or ...

Not if you use a hiltie gun

Gah! Now I'm going get all annoyed again

I absolutely hate what they did to totally destroy what would otherwise have been a very enjoyable song

Always pleased to hear of a sucessful fix, especially when it means a substantial bit of kit is not going into landfill

Fading to nothing then jumping back suggests a heater fault. Are all the valve heaters looking about the right orangy colour?

As for the low overall volume, I don't know this amp, but are you on the right supply voltage setting.

You should be able get them from RS components, Farnell or possibly CPC - this last is a more 'domestic' branch of Farnell. The black stuff is probably silicon rubber, and is intended to provide support for the caps to reduce stress in the pins. Once unsoldered, a bit of wiggling usually pulls the ...

How does one reach the upper switches? Do you need a broom handle by the manuals? :D That's what all the thumb-pistons are for! The picture is of the console of the Boardwalk Hall Auditorium organ (formerly the Atlantic City Convention Hall). It's the largest (and loudest) pipe organ... in the ...

You guys are really doing it the hard way. I use this stuff. Only I never bothered with the dispenser. I have a pair of longish MIDI cables with this type of label on them. They are over 15 years old, and are still secure. The ink that started out black has now faded to a pretty (but still readable ...
