I recently bought a 1959 vintage 14wpc Eico HF-81 integrated tube amp on ebay. The seller had upgraded the filter caps as well as most of the other caps except the ceramics which tested ok. Tube compliment is mainly Eico by Mullard, except the EL84's which are Eico, made in spain? They do sound good though. I bypassed the funky focus (balance) control which introduce gain and increased the volume when moving to the right or left channel. For the chassis, I painted the main panels argent silver, polished clearcoated the brass faceplate, and painted the cage gold to compliment the faceplate. These are really sweet sounding amps, and the phono amp is not bad if used with a mm cartridge.
