[quote:4e901741be="alfcat"]Dear t.,
I followed your link to the Regulator page ... but I have some difficulties understanding it. The thing comes as a DIY project? So how can we order the parts? I was in kind of hurry today when I visited the link and as I can't get much out of it, I lost my patience.
You can take a look at the last photo I posted. I changed all the large caps in the PS part to Black Gate already. That is how I boosted the S/N ratio from 65db to 75db or so.
I haven't got any Zener at home. Viewer had promised to send me one tomorrow to try out.
All the original caps I used in the wrecked PCB are now in their original places. However, I realised that my CD33 is not performing as good as it used to be. Really strange and disappointing.
BTW, is that your cat you are using as the avatar?[/quote]
Hi Cat,
Yes, the Flea regulator is a diy type, I ordered all the parts for mine from Farnell.
Now the CD33 op-amp stage has been bypassed its psu regulator circuit is not needed so I may try removing the 15v regs and run the clock circuit from there, I'll post pictures once I've tried it.
You will notice I do not use Blackgate caps, the reason being I do not like them, they sound too Euphonic/fake to my ears, I've tried all the grades from standard to NX Hi-Q, even after weeks of burn in they are not to my taste.
If you improve the regulation etc that will give far better results than BG caps :wink:
Give your CD33 a few days to run in, it should improve, did you apply lots of heat using your soldering iron when you replaced the capacitors?
Capacitors internal chemicals can change when the legs are heated, it can take a while for them to settle down.
Also be careful with using lots of Sanyo Oscon capacitors, their ultra low esr can make the output of regulators go unstable causing oscillation
BTW yes, that is my cat in the Avatar |
