The link below is for a former CAL authorized repair shop. They repaired my CAL Alpha a few months back. They phoned or emailed me every step of the way.
REX44, I took your recomendation and got the service manual for Tempest & Tempest II (is hand wrote and missing data but enough to repair mine, after test wasn't the transformer and my unit is working now.
Mine is the Original Tempest I(single chasis).
Now I will look for adjusting bias procedure,only for the Tempest II on those manuals.
Thank's and happy Audio.
