Pair of RCA MI-12222-B Mono tube amplifiers. Condition for both amps are overall good with rust and/or spots on the body. Please refer to pictures for condition.
This mono amplifiers in pretty good condition for its age. I’ve only performed a light cleaning. It is untested and in the exact condition that I received it in. I have not powered it up. I’ve not tested any of the Tubes. I’m sure it will need a check up by a technician and some components replaced. Take a look at pictures for the condition details.
This Bogen DB20 mono tube amplifier is a recent “barn find” survivor, housed in its original wooden case. The case measures approximately 17 inches wide, 11 inches deep, and 11 inches tall. This unit is in original, unrestored condition and appears to have been in long-term storage for many years. While the exterior has been cleaned, please note there is surface staining on the metal chassis and a slight musty scent consistent with its barn storage history. In an initial safety test, the unit powered on quietly and the vacuum tubes showed a healthy glow. However, during a subsequent attempt to film a video of the unit, I heard a sizzling sound and noted a burning scent. I immediately disconnected the power to prevent any damage to the transformers. Condition & Restoration: I have listed this unit in the “For parts or not working” category. It contains all-original 1950s internal components, including capacitors that have clearly reached the end of their service life. Additionally, the original power cord is in rough shape and must be replaced. To ensure safety and reliability, this amplifier must be thoroughly inspected and serviced by a qualified technician before any future use. This is a “pure” restoration project and a fantastic find for a collector or audiophile. The wood case and internal transformers remain the primary value of this unit.
Plugged this in and the tubes faintly light up, but that is the extent of which I have tested it. Cosmetically in Greta condition, but could use a clean, there’s some dirt all around. See photos for condition and signs of wear.

EICO HF-12 Mono Integrated Tube Amplifier – Modified, Tested, Great Sound. A classic mono integrated amplifier from EICO’s golden era, the HF-12 is well regarded for its musical EL84 output stage and straightforward, no-nonsense design. Tested and fully functional at time of evaluation. Modified to use a solid-state rectifier in place of the original EZ81 tube. Provides more stable operation and consistent voltage. Evidence suggests some of the capacitors were replaced in the past by the prior owner. Exact timing and scope of this work are unknown, but several current capacitors do not look like original factory capacitors. A full recap is recommended for long term reliability. Three 12AX7 tubes (installed and included). Brand may vary but all tested strong, no shorts and gas detected. Old tubes were all replaced for reliable performance. Classic EICO iron and EL84 sound signature. Strong, engaging mono presentation-excellent for vintage speakers. Clean cosmetics consistent with age. Some corrosion typical of age. Solid platform for continued enjoyment or future restoration. This is a vintage tube amplifier.
