Oatley K272C JAN6418 tube based headphone amp kit

In this build I used bituminized aluminum foil to line the ABS plastic compact enclosures and switched 6.5 mm stereo phone jacks. Only with both source and headphone plugs inserted and the press button switched β€œon” at the rear will power flow. Wire-wrap wire has been used in the signal path and the battery health LEDs have been brought out to the front of the enclosure. The sound appears to have better bass than previous models but the tubes will ring if struck.
