Wish to buy an omnidirectional condenser microphone with self-noise of ≤10 dBA -- preferably one with selectable directvity (omni, figure-8, cardioid).
Hoping to find a Rode NT2000 for a good price (cosmetic condition does not matter much, as long as it meets performance specs), but any other similar mic would work.
Can exchange for modern computer parts (Ryzen-era), server parts, LTO-6 backup tapes and/or drive, electronics test equipment.
