Ningbo Alctron Electronics Co., Ltd. HST-11A
Multi-Pattern Tube Condenser Microphone
The HST-11A is the best-known Chinese clone of the AKG C12 design — a dual-diaphragm, tube microphone with 9 polar patterns selectable via a switch on the power supply. It has been rebranded and rebadged under numerous labels; see the “related mics” in the sidebar. The Apex 460 seems to be the best-known label. The Nady TCM-1150 is another well-known rebadged HST-11A.
These mics respond well to aftermarket mods, such as swapping the capsule, transformer, tube, and capacitors, resulting (to some ears) in a sound and response characteristics that rival the C12/ELAM251 — mics costing over $5000.
The spec for one such mod can be found in the Yahoo “Micbuilders” group; see the German C24 Solo Tube Condenser plan (you must first join the Micbuilders group).
Alctron mics are not available in the retail channel, except through the “rebadgers,” although there are stories online of people who have successfully imported small lots of Alctron-badged goods. Freight charges often equal the mic prices for small orders.
The Ningbo Alctron Electronics Co., Ltd. HST-11A is also known as: T11A, T-11A, HST11, HST11A.
