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.

Not yet, I never got a round tuit, sorry.

It's on my list, but life keeps getting in the way.

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?

Re: Interim replacement for Denon 103R - suggestions?

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.

Yes, one PCB is suitable for a single 300B, I have spare PCB. It sounds like you need a pair?

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

I can get some boards done. I was hoping there might be a few takers to help cover costs, you need to order a decent amount to make it worthwhile. SMPS would work fine on the smaller PCB, but you might get HF artifacts breaking thru. Nevertheless, as long as the heatsink can cope, which it should do...
