    Preamp with gain vs Power Amp with more power

    I'd just like to clarify the above statement. Its essential to use the correct tap on the output transformer otherwise the output valve(s) will see the wrong anode load and may operate on the non-linear part of its characteristic curve thus leading to excessive distortion amongst other things.

    Flexible and home working and custom and practice

    Exactly! I am sitting on a top notch office chair bought for me by my employer more than 20 years ago. I also have the telephone and other kit that they provided for me at the same time to WFH! My role was global and I often held meetings in the early hours to bring on board AP and the US/LA...

    Chromecast audio and windows 11

    It was worth a try. Did you reboot the laptop to enable the change? DV

    Chromecast audio and windows 11

    I've never used Chromecast but it may be that you need to turn on SMB v1 (its off by default) in Windows 11. You can do this in the Windows features pane. DV

    FM antenna - clearance *around* the antenna?

    I run my old Windows games and even dbpoweramp via WINE. DV

    Plain jane amplifier?

    I would have preferred to see a speaker impedance and phase angle curve but from the snippets given in that link these speakers appear to be a difficult load to drive. My Shahinian Obelisks are also a difficult load and I eventually settled on a pair of big beefy amps that can provide both the...

    Why should teachers have a pay rise?

    I think it depended. I didn't get any free periods until I was head of department in a newly created comp. I think it was something like one double period a month. Of course it almost always went on standing in for an absent colleague. I only had a Saturday off. Every night of the week was...

    AI and human communication

    I don't have your experience but a few years ago I did build a PC to study ML and DL. I don't like to use the term AI as its misleading as can be seen on pfm. I had to build separate models for each intended purpose. Then I had to train those models from the huge but free online databases and...

    Help identify this Windows popup please

    This is unnecessary in a normal Windows install. As I mentioned above there is a Reset this PC option under the restore options. This will re -install Windows from the recovery partition with the option to keep your files or wipe everything. Always provided that the recovery partition hasn't...

    Help identify this Windows popup please

    I've had three machines like that on my bench. One belonged to my daughter who was begging for a new machine as her Macbook Air was 'dying' so she claimed. Basically it (and another Windows machine) was full of crap that was calling home over the Internet. Its now back in use as her portable to...

    Help identify this Windows popup please

    What i would do is remove the HDD and put it in a USB case and install an SSD - they are quite cheap today. Then download and install Win 10. Provided you install the correct version Home or Pro Windows can be activated with the original key thats stuck on the machine somewhere. All the old...

    Transistors in WW2, surely not...

    Transmissions would fit as telephone conversations can be encrypted using a scrambler to make transmissions secure from eavesdroppers. DV

    Help identify this Windows popup please

    Why not just reset Windows you can keep the data if you wish. As to your question Windows is trying to connect to a server. Check the start up apps and look in File Explorer under This PC for server connections. DV

    Bitcoin

    Cash has recently earned about 5% and if that is saved in an ISA will be tax free and will beat current inflation. DV

    SSD/HDD failure

    Coming back to this statement "Another SSD has bit the dust, this time a WD NVMe blue drive. PC and Mac can see something is there," As I have already commented this doesn't sound like a failure but more like corruption. I assume that you tested this on the Mac via a USB port. using an adapter...
