About this model
The HF-20 is an EICO integrated amplifier from the company's mono hi-fi years. This one had been serviced before sale: a new multi-section filter capacitor, new coupling capacitors, and new Sovtek 6L6 output tubes. That is the standard first-stage restoration for an amplifier of this age, and it is the right order of work: power supply, then coupling capacitors, then tubes.
EICO sold its hi-fi equipment as kits or assembled, so the quality of an individual HF-20 depends partly on whoever built it.
