  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.

NAP140 on steroids

    I don't know whether to put this in here or the main classified room.

    I have a shoebox amp that I built myself and served as a pre-prototype for the Witch Hat amp. It's taller than a Naim box but roughly the same width and length.
    It comprises:
    2 x NAP140 boards with 2sc2922 output transistors and 47uF film feedback caps
    Avondale minicap6 power supply with 10,000uF Kendeil capacitors
    Canterbury Windings 300VA 30-0-30v custom transformer with shield winding.
    4 pin DIN and RCA phono inputs, but no pre-amp supply.

    It's been poked and prodded a bit and currently has a passive Alps Blue 20k volume pot wired in but no front panel. There's a pushbutton switch in the front.

    I'll upload photos later.

    Is £450 a reasonable price? Contact me through PFM please.

    Tidied up. I have removed passive volume control and put a front panel on it.
    This looks like a finished amp and is in the main classifieds now.
