The TG12345 was the console that ended the valve era at Abbey Road. Designed by Ken Townsend and the EMI CRL team, it used discrete transistors throughout — faster, quieter, with lower distortion than the valve REDD designs, but still transformer-coupled at every input via the legendary Marinair transformers. The transistor circuitry gave the TG a more open, extended top end and a faster transient response. The Beatles' final two studio albums and Pink Floyd's entire run of 1970s records were made on the TG12345. It was eventually replaced by API and SSL consoles, but the TG12345 design remains one of the most admired transistor console topologies ever produced.
