Hello and thanks for taking the time to read this post.

 

 I purchased a pair of quad boards from here :

http://cgi.ebay.co.uk/DIY-Stereo-Audio-Power-Amplifier-Assembled-fr-QUAD405-/160556333192?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item2561e73888

 

  1.  Does anyone have experience of these, How do they compare against standard quad boards.

 

  2. The first four luger-style connectors are identical to my quad boards: that is phono input, then speaker out, then -54volts, then +54 volts, unfortunatly there is a fifth luger connector labelled " gnd " which my quad boards do not have, i contacted the manufacturer who said it is the power ground, so i connected it to the smoothing capaitors of the power supply, when switching on i got massive distortion then both boards blew. Does anyone know where i went wrong.

 

 Many thanks in advance.. John.
