On special request we now offer user roll-able I/U transistor as an option in the Special and Signature versions by installing sockets instead of soldering the transistors directly into the circuit.
The roll-able I/U transistor option enables to customise and to fine tune the sound further according to the customer’s preferences just like rolling tubes.
Rolling transistors is simple. With a little bit of practice is almost as simple as rolling tubes.
As with any component that has pins it is paramount to make sure that it is pin compatible and to observe the correct orientation.
