This is just a sweet amp all around: big honking transformers and PS, 2/4/8 ohm taps, front panel bias pot for each individual output tube, and bullet proof construction. Bias? Insert tube(s), power up and turn pot of each tube until LED is orange then dial it back slightly til the LED goes green…done. I will supply a set of lightly used Valve Arts KT-88s and NOS RCA 12AU7 clear tops, or $100 off selling price if you have tubes. As you can see from the photos, the amp is clean, no dents/dings/scratches. I've used fairly efficient speakers but heard it connected to big Thiels at VAC's facility; the 2-ohm taps aren't window dressing. Quite a beautiful, elegant amp when all tubes are glowing under power.
The form factor of the PA80/80 endures in the current model Phi 200.1, the 100W version of the Phi 300.1. The kinship is more than skin deep as the two available upgrades (below) will take this amp to Phi 300.1 level for about $1700 if done simultaneously, according to Kevin Hayes. That’s state of the art sound for about $3300 total, and a smart money approach to getting it. Original box and user guide included, buyer to pay actual insured cost and add 3% if using Paypal. Thanks for looking!
PA80/80 to PA100/100 $ 750 Revision of passive parts, revised chassis grounding, power supply noise suppression techniques, greater current capability in output tube pathway. New "PA100/100" badges at extra cost.
PA100/100 to "Phi 300.1" style input/driver upgrade $1,300 Fits the new front end circuit topology from the Phi 300, resulting in greater speed, dynamic, detail, and bass punch.
