About this gear
The ER211 is ELROG's reproduction of the classic 211 (VT-4C) transmitting triode, a large directly heated tube favored in high-power single-ended amplifier designs. Compared to a 300B, the 211 offers more voltage swing and dynamic headroom, making it suited to driving less efficient speakers while retaining DHT character. It's a choice for SET amplifier builders and owners looking for scale and authority without giving up triode purity.
