Black triangular plates, top O-getter,
dark silver lettering on brown base, all have the same date codes, packed on March 1962 in original military
boxes. Excellent slam and dynamics! These have really clear good mid range and solid bass but the top end is not as refined as the famous Tung-Sol VT-231 with round plates. Highly recommended as a driver
tube for power amps. Available in matched pairs and singles.

but may be higher depending on available stock.
