Description

Hand selected Wurlitzer electric piano 200A / 206A transistors: All new, quiet, modern transistors; not old stock 1970's technology that has been stored in a box for 30 years.  Also note that these are not NTE transistors, which are garbage. 

They will work fine without being matched but matching ensures the highest operation. **TR15 & TR16 Late model aux-out production started at serial #102905 (schematic #203720-S-3).  Be sure to select the correct version for your piano from the drop-down menu.
