Vintage Tube Amp

Up for sale, a 2007 Swart Space Tone Reverb in near-mint condition and in perfect working order. This boutique, USA-made 1×12″ tube amplifier packs particularly potent tone into a compact form factor, pushing 5 Class A watts via a vintage “coke bottle JAN-branded 6V6 power tube. Essentially a hot-rodded spin on Fender’s 5F1 Tweed-era Champ, the Space Tone Reverb has streamlined controls with a Hot/Clean switch that toggles between touch-sensitive, glassy cleans and absolute searing drive when pushed hard, with independent Hi and Lo inputs and lush, splashy tube-driven footswitchable Reverb. The circuit is hand-wired point-to-point, cathode-biased with premium componentry including carbon comp resistors, Mallory capacitors, cloth hook-up wire, and CTS potentiometers. The tube complement currently comprises a JAN 6V6 power tube, Bendix 5Y3WGT rectifier, two RCA 12AX7s and a 12DW7 in the preamp. The cabinet is loaded with the original Mojotone British Vintage Series BV-30H 12 ceramic magnet driver, and the tube chart is also intact inside the enclosure, dated 11/20/2007. The cabinet is built from finger-jointed solid pine, and cosmetic touches include a vintage-style jewel LED, black basketweave tolex, chickenhead knobs, and a salt-and-pepper grillcloth with Swart badge. This is a clean example, with just a couple tiny marks on the tolex; the faceplate and graphics are pristine. 5W CLASS A BIG sounding w/Monster fuzz tone at max! 100% Tube Circuit – GZ34 Valve Rectifier (5Y3 or 5U4).

This has been on the shelf in my warehouse for over 20 years. The tubes in photos are included. Nothing has been tested. Please see the many photos provided. Amp has not been powered up in years and should be looked at by a qualified person before use and any repairs preformed it may need. From a large collection of tube related gear.

This is the mighty H. Scott model LK-150 I picked this item up from the owner of a electronics repair shop. He overhauled the unit replacing all the capacitors and other parts that were needed. He also replaced the power transformer. The original part was no longer available, so he replaced with separate transformers. This unit can crank out 60 watts per channel all day long. I will also include the original build/operating book. Please view pictures if you have any questions please ask. I also have the matching pre amp for sale separately.

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.

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.
