CAT JL-2 amp upgrade


I have a CAT JL-2 power amp, version 1. I know there is an upgrade to version 2. Has anyone had it done? What did it cost? How long did it take? What were the results? Thanks for your input.

Thank you for responding, Wadia 150. By your comment, I assume you had the upgrade done. May I ask how much it cost, how long it took, and the sonic differences you noted between the JL-2 version 1.0 and version 2.0? Did you keep your JL-2 after the upgrade or change amps? Thanks.

Hi, Johnny.
Do you remember how long it took CAT to return the amp? Do you know what they did internally to the amp for the standard upgrade, or do for the Signature? Did the changes to the amp reveal any changes necessary for the rest of your system, particularly cables or power cords? How many hours did you put on your original tubes before retubing? Do you get a warranty with the upgrade? Thanks for any further information.

I am now using a Manley Steelhead phono preamp as my preamp and running it directly to the JL2s. Much better than my CAT SL-1 III preamp.
Still using my JL-2 original version amp. Has anyone had the upgrades to this model? Are they worth the money? Has the reliability been improved? Mine blew something expensive awhile back. Thanks for any information.
