Foldr Project

Spalding 3 speed
A Japanese folding bike that resembles a Raleigh 20. 

The Shimano 3 speed internal gear hub that came with it has some issues engaging the top gear.


But this laced and trued set of Araya rims with a Shimano Nexus 3 hub for the rear should fit.

Radiotron Designer's Handbook


Most of my knowledge in Audio DIY have been gleaned from the Radiotron 3rd Edition. The 4th Edition is just over the top of my head, but looks better sitting on my bookshelf ;)

RC-12 Tube Manual

All the tubes I am using in my Hi-Fi System were being manufactured by the time the RC-12 was published.

RCA phono from RC30

But I also keep an RC30 copy!
