Torii MK III, walnut base, matching walnut stepped volume knob,  VCAP upgrade, Shuguang 6CA7-Z Black Treasures tubes, matched quad set in super shape replacing stock EL-34. The balance of original tubes were replaced not long ago with mostly NOS replacements at a cost. I will send original tubes too.  I recommend Decware speakers for a perfect match if possible. This amp was used sparingly due to multiple systems. Upon sale I will cover cost to ship insured amp to Decware for warranty certification to new owner inclusive in purchase. Decware in-turn will ship amp to new owner, shipping at new owner's expense. Amp is in absolutely perfect condition in all regards, Decware will certify. Investment approx. $4K+, Sale price: $2400. plus fee's like PayPal, shipping from Decware to you.  Price is firm. You'll get a fantastic amp that is like new with a Lifetime Warranty in your name.
