43% OFF NEW RETAIL! 


The crown jewel of the Jadis lineup, the JA-30 MKII. Not to be compared to the original JA-30. The MKII brings real, widely accepted improvements to sound quality. This set of mono blocks was manufactured in 2020. They have been meticulously cared for and previously owned by my good friend. The finish on the brass and stainless is excellent and indicative of the excellent care these amplifiers received. Looks like new!


This set of amps has been configured for 30W allowing use of EL34. KT90, KT88, KT120, or 6CA7 power tubes. With a small modification, they can be converted to 45W using the KT150 power tube.


It will come with new production Tung Sol tubes in all positions.


NOT INCLUDED but FOR SALE SEPARATELY is a FULL SET of Wathen Audiophile CRYOTONE tubes to include the following:

EL34: $139 ea X 4 = $556

ECC83: $122 ea X 2 = $244

12AU7 Long Plate: $150 ea X 2 = $300

MSRP: $1100

WILL SALE FOR: $700 in addition to the sale price of the amplifier.


These tubes are absolutely exceptional and do everything right. They are highly regarded for their exceptional performance and have been praised by industry experts like Steve Deckert of Decware. I had the pleasure of hearing them at AXPONA last year. I started with input and preamp tubes, then went full bore. I have tried other tubes and while the Jadis JA-30 is incredibly forgiving with a variety of tubes, these Cryotone tubes are on another level. Noise floor is dB's below many of the boutique tubes I have tried. They are truly a wonder match with these JA-30's.


I have had the tubes for about 3 months. They have less than 200 hours on them.


I am selling the amplifiers because I changed my speaker system and have an amp that is a better match. I do not collect audio gear so that is the reason I have decided to put them up for sale.
