I built this amp 6 years ago, but it’s too loud for me to open it up when I play in my house. I assembled it from a kit by Boothill Amps, so the parts are high quality. You can look at his website for more information. It’s a 5-watt 5F1 “Fender Champ” circuit. The speaker is an 8-inch, 4-ohm ceramic Warehouse G8C. I bought a tube set directly from Dave at Boothill Amps because he said that a USA-made tube rectifier would be more reliable and keep the amp at the proper voltages. The newer modern production 5Y3 tubes run at higher (hotter) voltages. Keep this in mind if you plan on replacing the 5Y3 rectifier (far left tube, V3) and/or the 6V6 power tube (middle tube, V2). He sent me a USA-made RCA 5Y3 (rectifier) tube and a USA-made RCA 6V6 power tube. These are vintage tubes, but I’ve read that rectifier tubes last a long time. The V1 preamp tube (far right) is a brand new modern Russian-made TOL-SUNG AX7. I will include these three tubes with the sale. The transformers I used are now difficult to find: a USA-made ClassicTone 40-18019 (Power Transformer) and a ClassicTone 40-18115 (Output Transformer). The pine cabinet is unbranded and came with the kit. It’s well-made and covered with raw (unlacquered) tweed. See photos and video for details.

The Lazarus Hybrid Amplifier is a rare and highly sought-after hybrid stereo power amplifier designed by Greg Miller and built in North Hollywood, California. It runs a cascode-connected 6DJ8 dual triode input stage driving complementary MOSFET output devices, with all circuit voltage gain derived from the tube front end and no overall feedback loop – a topology that delivers the warmth and dimensionality of tubes with the authority and control of solid-state. Power output is rated at 50 watts per channel into 8 ohms in Class A, doubling to 100 watts into 4 ohms and 200 watts into 2 ohms, with the ability to bridge to mono for 200 watts into 8 ohms. Owners consistently praise its ability to reproduce the deepest soundstages they’ve encountered, with zero listening fatigue even after extended sessions – a testament to the amp’s fundamentally musical character. Built like a tank in a 2U rack-format chassis weighing 35 lbs, the H-1A is an extraordinarily rare piece of American audio history that competes comfortably with amplifiers costing many times its original price. In good cosmetic condition, has some scratches/marks, see pictures for details. The unit has been cleaned inside and out to remove dust, debris, and surface blemishes. The interior was carefully vacuumed using a soft-bristle brush to ensure gentle yet effective dust removal without damaging internal components. Only comes with what you see in the pictures which includes the unit itself only. Unit powers on but the DC offset measured too high for safe use and testing so it has been deemed a for parts/repair unit. The unit was not tested further after the DC offset was measured. Please note the unit does not include tubes. At HTF Audio, we put care into every unit we list-cleaned, tested, and ready for its next home. Unlike general resellers, we focus mainly on audio gear, so everything we sell gets hands-on attention, from detailed functional testing to cosmetic work. Most of our listings include a custom video so you can see performance for yourself. If something is shown or missing in the images but not mentioned in the description, the photos take precedence. Only items explicitly shown or listed are included-this excludes any accessories, cables, or original packaging unless stated. Please message us with any questions before purchasing. This does not specifically mean that this item is an “as is” item unless stated in the description above.
