The product is a vintage ELK 1-12 guitar amplifier from the 1960s or early 1970s, The original circuit board was removed. I was ask to build a prototype of an 18 watt with only a volume and a tone control. The company send me three amps to build off of, when everything was said and done. They gave me this one, because they decided to build heads and not combo amplifiers. I got it out this week to test. It’s been in storage for many years. There is a little transformer hum. I played it for a hour plus last night. Nice pick attack, a great sing to the notes. It features an EL84s and two 12AX7. Has about 18 watt’s power output. A solid wood cabinet, around the size of a black face Dlx. All sales are final. Please look at May other items.

I’m letting go of a few things from from my collection, including this Audiotronics model 300 vintage tube amplifier amp project. Will make a killer guitar amp. If you like the Filmosound stuff, and single-ended amps, this one is great, rare and has a cool look with that front panel, just tweak the circuit and add your preferred controls. Has nice Triad power transformer, good sized output transformer, 6×4 rectifier, 6bq5 (el84) power tube, and a 6av6 preamp tube. Looks to be in stock form. Not currently in a working state.

Some machines are built to be used. Others are built to be. This pair belongs to the latter. The EICO HF-32 is a well-regarded integrated tube amplifier from the American hi-fi era, appreciated for its musical warmth, straightforward design, and the unmistakable character that early tube circuits deliver. It is the sound of living rooms where jazz records spun late into the night, where voices came through the air with presence and humanity, not compression. Paired beside it is the EICO HFT-90 FM Tuner, a companion piece that completes the picture – a reminder of a time when radio was not background noise, but an event. Together, they form a visual and historical symmetry that collectors seek but rarely find intact. Look closely and you’ll see the story written in metal and paper: the perforated steel cages, the understated typography, the surviving schematic labels still clinging to the underside like handwritten notes left behind by the engineers who built them. They are the difference between equipment and artifact. This set has not been powered on. Tube audio collectors understand that preservation comes before assumption, that restoration is a personal journey best left to the next steward. What is offered here is honesty – untouched, unaltered, and ready for the hands of someone who understands what they are holding. This is not a shortcut to sound. It is an invitation to history. Professionally packed with care appropriate for vintage electronics. The HF-32 occupies a respected place in EICO’s tube amplifier lineup for a reason. HF-32 is often spoken of in reverent tones for a reason. It occupies that rare intersection of engineering excellence, musicality, and aesthetic restraint that modern equipment rarely attempts. When paired with its matching tuner, it transcends utility and becomes a statement – a moment frozen in the golden age of American hi-fi. Opportunities to acquire a matching EICO amplifier and tuner pair, preserved in this state, do not present themselves often. This is a piece for the collector who values authenticity over convenience, and legacy over immediacy. Collectors familiar with EICO’s lineup will recognize exactly where this piece fits.
Quad of EI Mullard EL84 6BQ5 Made in Yugoslavia Vintage 1968 Vacuum Tubes. Test good on my tester. I removed from a working Vox AC30 guitar amp I owned a number of years ago. Date codes appear to be KM4 Q(not actually a Q but a similar looking character which represents Yugoslavia) 81 which indicates Nis, Yugoslavia 1968.
This is used with light wear and is in great condition. It has no bottom cover or top cover/cage. I believe this normally uses a 5U4GB rectifier, four EL84 output tubes, and two 12AU7 tubes. The tubes are not included. The rectifier is included. This has a few new caps underneath, but may need more work, though it will honestly probably work fine like this.
