I am the second owner of this incredible preamp in excellent condition, I am listing it as an 8\10 but truly more like a 9\10. The original owner was a personal friend of Ken @ CAT. I have the original manual and box. i currently use this strictly as a phono preamp. If you know about CAT you understand how remarkable it truly is, I would guess thats why the never show up on the used market. I will include the original tubes witch have VERY low hours due to the fact I changed them out for some Telefunken smooth plates and Amperex Bugleboy type tubes witch took this pre to a whole new level. The Only reason Im selling this unit is to move way up the food chain. Local additions are welcome and encouraged. If necessary Ken@ CAT can be reached to confirm the serial# and the MK 2 model. I will include Insured shipping and Pay Pal fees with my asking price.
