Low Noise Transistors - ROHM 2SB737 Zetex ZTX-Series and Others
The classic ROHM 2SB737 is now available in limited quantities from 1980-era "new old stock." In addition to availability of classic ROHM transistors, modern Zetex "E-line" medium power transistors have low rbb' base resistance making them ideal for many low-noise, low source impedance, microphone and moving coil preamplifiers.
