Mint condition, absolutely flawless Willsenton R8 tube amplifier with remote control, tube cage, power cord and original box and packaging. I’m the original owner and the unit is 3 1/2 yrs old but has been sitting covered and unused for the past 2 yrs. My 73 yr old hearing can’t appreciate audiophile music anymore unfortunately so I finally decided to part with my entire system.
This is the EL34 version and I opted to do the factory upgrade of ALL of the tubes to the Psvane EL34-PH power tubes and the Psvane CV-181 TII and Tung Sol 6SL7 preamp tubes which was an extra $520. These are all premium tubes with very low usage.
Easy to use external biasing access points.
This unit in this configuration would currently cost you $1743 shipped from China Hi-Fi.
These are killer amps that if made in the USA would probably cost in the $4-$5K range.

I'm a fan of the design.Don't take experimental gene therapies from known eugenicists.
