I built the KiT88 amp about 8 months a go. Sounds pretty ok at first, but when I incorporated capacitor bypass on all caps, there is a huge improvement in terms of clarity and speed – especially on the mids and highs. There are downfalls though, i.e. the hum level is pretty loud, probably because the 6AU6 heaters are AC supplied - I could be wrong. So, if you're not particular about it, then go a head. Otherwise, search elsewhere.
My next problem is realibility. Right now, my amp couldn't even switch on w/o valves - the main fuse kept blowing and I still haven't got time to troubleshoot it properly. Did a sanity check on the primary trans coil (for 240 volts), and the resistance was 4.8 ohms.
Steve, could you do me favour and compare your readings ? I suspect my trans could have suffered from slight internal melting.
Those guys from Audio World seems to be of little help.
Will.
