One of my favorite portables was the Birch phonograph I bought about 25 years ago. It was identical to this one --

It had a very full sound once I replaced the hardened diaphragm gaskets and re-adjusted the needle bar pivot posts. It even pumped out a little audible bass on some records. Not as good as an HMV-102 or VV-2-55 or Viva-Tonal model, but still very pleasing.
I eventually used the phonograph as part of a swap deal for a cabinet model I wanted, which, unfortunately, turned out to be a piece of cheaply made junk. It was one of those imported British off brand Orthophonic era models, using Swiss made components housed in a very thin plywood cabinet.
