OPEN TO FAIR OFFFERS. The listing price is for a. EICO HF-60 Mono Tube Amplifiers based on EL34/6CA7 Tubes. No tubes are included. The tubes shown are for testing only; not included. The output transformers are the sough-after Acrosound TO-330 As far as I can tell, they are in original configuration. I hooked them up on a variac, set up to 80v. Both powered up OK. One amp generated hum sound but did pass music through to the connected speaker. The other didn’t produce music nor hum. On this amp, the connected speaker did produce cracking noise as I wiggle the small tubes. So, at least, the output and power transformers are all good. By visual inspection, I can tell they are reasonably nice; no signs of abuse, burn, damage. Shot me any questions and I’ll try to answer. I have other audio equipment, like.
