Philips AG9016 Tube amplifier. tubes 2x EL95 & 2x ECC83 (12ax7) – Early 1960’s
This is an early 1960’s Philips AG9016 tube amplifier in good restorable condition. It uses 2 – ECC83 (12AX7) tubes and 2 – EL95 tubes. The only testing I did was to power it up first using a dim bulb tester to check for shorts and it tested good for no shorts. After that I plugged it directly into the socket and as you will see in the last photo, the two ECC83 tubes light up, but only one of the EL95 tubes lights up. Please see photos for cosmetic condition. This amp is made so it can be set to work on 110 or 220 volts (see rear side).
