That's a good point, Nick. I'd forgotten about that little trick.

Re: 300B Headphone Amp

I tend to agree, not enough headroom, but worth trying, from memory you need 3v DC, at least.

If you try the resistor, I'd be tempted just to try the resistor in the "positive" leg of the transformer, first.

Re: Our friend Nick Baker

Sad news indeed, another "silent key" as the hams say. I saw Pepperoni and the rest of the "Bristol gang" at the last proper show I did with Nick, Dave and Ali before the pandemic hit :(

Best wishes to Nick's family.

Re: Cole lcr phono stage rebuild

Hi Andrew, Andrew said There's a good mathematical reason why LCR sounds right, if implemented correctly, the phase should be correct across the frequency band, you can't do that with just RC, right? I don't think I agree with that as phase is a reflection of frequency response so with the same res...

Re: Cole lcr phono stage rebuild

In following phono stage design over the years, one constant seems to always come up. When someone has or hears an LCR phono, they all say there's something right about it; a natural presentation that they can't quite figure out but they know it when they hear it. Many DIYers seem to stop building ...

Re: DHT Heater using VCCS - PCB or Kit (Possible Group buy)

I have a new batch of PCB, Phil, if you want to 'speriment? Can you remind me Andrew, do your boards have a trimmer for fine tuning the output ? Yes, but I also keep saying trimmer pots are rubbish, and not to use them. Sadly, I am often ignored ;) However, if it's a prototype then I'll excuse you.

Re: Some thoughts on Vitamin D, flu, etc

Shouldn't VitD levels and supplements be prescribed, I thought taking too higher dose of the supplement could lead to kidney damage?

Those EsCo stylus have a habit of doing that, I like the sound, but wouldn't get another, I had two do that, try a VDH retip instead.
