  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

  3. May I please request people check and update their email address if it is out if date. I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

  4. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

Avondale front end deregulation.

    One of my lads has been commenting that my system had lost a bit of something and I feel I have tracked it down to the vbe regulation of the front end of my Avondale monoblocs. I have gone back to the resistor and diode combination for now but will look into a separate supply to the front end. My Cap6 modules were running at 54v per side when I was checking the bias current and I would like to match or even exceed this a little. So I'm looking out for a pair of nice transformers for the job and perhaps a few teddyregs. I think the vbe regulation stole some of the grip at the lower end. Cheers Andy.

    Andrew,

    A quick question, what voltage are you running your NCC200 modules at?

    Hi, 54-0-54 according to my test meter when setting the bias current. I don't know what the voltage is under a proper load as I have not measured it. Cheers Andy.

    what Les said ..i actually bodged a couple of amps , using NCC200 boards , one ran a mini cap6 module , the other NAP250 regulators , I prefered the min cap6 version.
