glad to hear you fixed your problem. gotta love those digital connections!!

be careful with ac isolation transformers - they are rated for certain amperage and are generally rather expensive for high current necessary for power amps.

cable tv induced hum is common - a pair of back-to-back 300 ohm to 75 ohm baluns are very effective in blocking hum induced on connection to the input cable from the street.
