I look at this forum a lot but seldom post. Here's a few pic's of recent builds and a video of the end result. The specs are home bent and welded aluminium chassis, Hoffman layout, own wind transformers and choke. 5Y3, 6V6, 12AX7. Output transformer, grain orientated core, switchable plate load (5K and 7K). Power transformer puts out 315V on plate with 5Y3 or 340V using 5AR4 rectifier. Switched gain stage bypass cap and NFB. Sounds best at lower voltage. Video was just a bit of fun and not intended to be an amp test as such. One of my mates playing, using a loop pedal and a hit of OD pedal at 1.56.
