Wurlitzer Solid State cross reference
A tour of the Wurlitzer factory circa 1947...
Last edited June 19, 2914 - I need to verify this list, please be careful...most are good though!
Just added - here is a sheet on Wurlitzer transistor pinouts, and another on finding the correct substitute, along with reforming capacitors...
