Thanks Chris,

The most challenging part was getting the layout correct in terms of keeping all wires as short as possible to reduce any chance of noise from the amp and making sure all the wiring was nice and neat. I'd already read a few books about amplifier design and construction so I knew a few tips about lead dress in amps and reducing noise from the tube filament heaters etc... And to bring the amp up in power slowly for the first time using a Variac not only for safety reasons but also to allow the electrolytic capacitors time to charge and form properly the first time.

The thought of building an amp was a bit daunting at first but as long as you take your time and follow the wiring diagram and schematic closely and double check everything as you go it's really not as hard as first thought and plugging a guitar into it for the first time was great fun!!!
