My first bass amp which I also used for guitar was a 15w Broadway in two tone red and cream. The amplifier was housed in the speaker cabinet in a separate cabinet this could be slid out to separate the amplifier and eliminate shaking the valves when playing bass. It also had a built in tremolo 12" Goodmans 15w speaker. I sold it to get my first Vox never seen one since?
Our first PA amp was a Vortexion was valve and had a grey metal cabinet and 2 chrome carrying handles. It was rated at 15w. I think we used Selmer columns which fitted together face to face with locks securing them together.
My first recorder was a reel to reel Ferrograph which at the time was an amazing machine and I sometimes used itas an amp
Wish I had kept them all
