Reluctantly, I am selling my ZMA with 25th anniversary mods in a beautiful walnut base. This is a great amp with every bell and whistle possible, plus some amazing modifications done by the previous owner.  Here is a partial list.
- 25th anniversary modifications
- professionally machined extended bias knobs (very usable)
- XLR and RCA inputs with professionally installed selector switch
- KLEI Perfect Harmony silver RCA inputs
- signal wires upgraded to Mundorf silver/gold/copper

Currently enjoying 7027 tubes but have 3+ full sets of other tubes, all in low or no time working condition….KT-88, KT-66, EL-34, and a few others…more than $1000 worth of tubes.

There is a slight scratch on the front right corner of the base, but otherwise in great shape.

Will ship via FedEx in its own Pelican case with a separate box for the tubes.

Asking $6900 shipped in lower 48.

Listing on Audiogon for $5900
