This eBay listing is for ONE Cary Audio CAD-808 Rocket 88 Tube Amplifier. Used and in excellent working and cosmetic condition. I bought this brand new from Cary in 2003 and it until now has been in storage for the past 10 years. The only blemish I can find is a super small spot of discoloration on the Cary label which is on the power transformer. This amp puts out 20 watts per channel in Triode mode / 40 watts per channel in Ultralinear. I sent it to Cary in 2005 and had it upgraded to utilize the 12BZ7 tubes instead of the 6922 tubes. You can use both 12BZ7s or 12AX7s if youd like... The BZs sound best though. Comes with 2x Electro-Harmonix EL84 tubes, 2x RCA 12BZ7 tubes and 4x Ruby KT88 tubes. As for the output tubes....You can use the EL-34, 6L6, 6550, KT-66, KT-77, KT-88 or KT-90 flavors. The two 1629 Green Eye tubes on the front plate are mesmerizing to watch, They display the power output. The 12BZ7s come with silicone dampers installed. I am going to drop this amp off at Mojotronix for a once-over where it will get a thorough check-up (Pots, Jacks, Contacts, Tube sockets cleaned, Caps checked, Tubes checked, Confirm all components working at spec, Bias the output tubes). I am having this service performed because the amp has sat idle for the past decade AND I want to assure the next owner years of trouble free operation. Comes as shown with the tubes mentioned above and the cable for setting the tube bias. This amp is heavy... 50lbs! I will double box it and use Insta-Pak foam to assure a safe delivery to you. I will pack the tubes in a smaller box and ship them separately. I will give it my 30 day No DOA warranty. Buyer pays $100 S/H via FedEx Ground. Buy with confidence from Esoteric Specialties !
