Nice work on the chassis metalwork. Are the folded end caps spot welded by yourself?

Nowadays its done at my mates workshop. It's a 2mm blank aluminium chassis, all I need to do is drill the holes with a hand drill with a step drill bit.

Have glued half the cabinet. Will glue more later. Reverse rabed joint similar to Morganamp's rusty cabinet. Quite strong, just takes a lot of time to accurately cut it.

The talent on this forum is always surprising. People with serious day jobs who by night are musicians and technicians.

Had a bit of time to complete the mini ods. This one will be going out to America next week. Gonna tidy it up a bit more before sending it out. Been finishing quite late at work so onky working on my amps as much as possible in the evening.

By the way, since upright power transformers are not common in Japan, has anyone tried mounting an L-bracket on a standard horizontal/through PT and then setting the transformer upright as shown?

I usually do this when the amp is jammed with parts, but most of the time though, it goes through the chassis. Some may not think so, but it has worked for me. Of course I will change to upright when I get to NZ🀣. If it's locally available there that is..

I generally use Hammond iron (PT, OT, Choke) & usually get them from Mouser.
