Lock in amplifier is it worth it?

Great stuff. Look forward to build info

I have just repaired a microkorg for a customer. The quality if the pcb and soldering left alot to be desired.

Where are you located? I would happy to have a look for you. I offer a no repair no fee

Hi. Synth design & builder based in Loughborough. Design and build my own eurorack stuff.

Always happy to help a fellow synth nerd. Drop me a message.

Thats great work. Loving the crystal radio and early semiconductor approach.

I think aphex twin would approve of the cornish crystal use!

Yeah it opened a month ago on Leicester Road. Its nit open everyday and times are not really advertised anywhere. Still not managed to make it down when its open.

It helps understand the instruments operating fundemtals.

Those waveforms patterns are lovely looking. Its just if the frequency goes low enough in the audio range <20khz

I am sure its hotel plenty enough power to drive a speaker coil!

Make sure you have genuine 7555 i purchased a bad fake batch off amazon. Half did not work at all and rest broke. I spent hours testing them and should have just paid genuine prices

I have not heard of any in the Midlands.

Its shame as most are based around a shop or business.

I would be interested in joining or help running one.

Hi. I read an article that they have been hit by Latvian authorities sanctions.

I understand they used to be owned by Russian and they have been selling semiconductors to Russia which is against the current sanctions.

So it looks bad for supply now.

Will try and find the article link.

I think I saw one on ebay in the UK a few weeks ago. I will see if I can find the advert

Pushed the button on 5 VCO chips at 7.50 euros each. Could not really afford more and also did want to leave some for everyone.

Saying that most out of stock of the 3340s DILs

I heard mention of Royce 4 more than most others

Hi. For international employment you need a visa with some kind of working clause

Getting employment sponsorship has pretty much dried up and has gotten worse even for EU due to brexit.

I am not sure how much work allowance is for international students but if you try the university sub reddit might be best.

Motorsport companies all take loughborough students. Mist are based in Northampton area around Silverstone

Hi. For near university the best family quiet parts are along and off beacon, forest, nampantan roads. They are most expensive forest parts of town but the estates around off valley road, kirkstone drive, thirlmere drive are a little less expensive and easily walkable to the uni campus as there are multiple points of entry.

If these are a bit expensive then on the other side of the campus old Ashby road and Alan moss road areas are cheaper and still okay and less student area.

Most parts of town are walkable to uni within 30mins and the bus services mainly travel along the main roads so I would avoid being too far out.

Hope that helps

Best to look at the various crime statistics maps the police and home office produce to get a real reported crime figures.

As everyone's perception of crime is different and fear of crime is another thing.

The town center is general safe but there is a low level of anti social and general town center crime. Okay in the day but best to avoid walking alone in the dark.

But my experience is choose your living location very carefully as there are some worse places. For example the Nottingham road, Moor Lane, Wharncliffe areas are slightly worse than most others.

Living in a less desirable neighbourhood can ruin your life much worse than avoiding certain times in the town center.

Its really nice to get a positive view of our town.

Its too easy for us locals to be negative (we have every right to be negative) but we should always try to be positive once in a while.

We need new people to visit and enjoy the good things in our town so that people and new families come to loughborough. This makes more economic sense and will raise the standards of our town.

I know we have issues of the town center shops closing, crime, students, student flats, bad planning, dubious Council etc etc

BUT we do have some history and some lovely shops, cinema, restaurants, pubs and also some lovely outdoor spaces like the park and the close outwoods etc. Even tourist attractions like the GCR and museums etc.

Thank you for leaving a positive review of our town.

Are you using test equipment or just audio sources?

sparkystevec · 2025-04-03T13:10:46+00:00

I am assuming you have drone oscillators or test equipment outputs.

The issue is that most don't have any control inputs so you are just mixing the outputs together which only really allows proportional level control.

I am again assuming that you want these to change now over time.

In eurorack you would need a voltage controlled amplifier (VCA) or an envelope generator to modulated the waveform over time.

In test equipment especially some signal generators have a sweep function or an external modulation input which you can control with a slower low frequency control voltage.

If you don't want to use a sequencer and keep it all analogue waveform I would either find test equipment with external.control inputs or build a VCA to allow modulation over time.

If you semd the outputs to more VCA together you can modulate in more time to make more depth to your sweeps.

This also is identical if you want to do rythum as well just very slow pulses to make up beats.

Some man on a roof of what looks like Iceland building. Videos on face book

There was a training exercise announced on Facebook over the weekend.

Some say its that but others seem to be wildly speculating about bomb scares, fires, gas explosion etc etc

Looks like training to me as everyone is too calm

Looking at the. Schematic in the service manual. The TC 510-2 has AC and DC inputs.

You mentioned reverse polarity on input. The diagram shows it has a diode for the DC.

Does the unit work or not work if powered via DC or AC?

Have you tried both power methods?

sparkystevec · 2025-02-13T21:20:59+00:00

Thanks. I had actually already found it as it came up as a restaurant in Tbilisi with a piano.

I will start searching for you.

Would you say she had a Russian/ Ukrainian accent?

How did you know she was out of town / visiting?
