Your preamp is a 6/05 production Transcendence Seven ECR with remote control. This is built in the big AVA chassis, but is before we went to the one big mother board design allowing 8 active regulators. Your unit has separate audio and power supply boards.
We can add the Transcendence hybrid phono board of the same vintage as the the line and power supply circuits. The cost is $499, $100 more than the option costs when ordered as a part of new production because the install labor time as a retrofit is much more complex to do.
Probably a more cost effective upgrade for you would be a complete Ultra EC upgrade; new mother board, eight regulators, 6N1P line tubes, new phono section, new higher current power transformer if not already installed, a new full vented cover and more. The upgrade price is $1299 and includes a new three year parts and labor warranty. Compare this price to that of a new unit with the same options, $2497.00
The music? Note what Dan Kolton just had to say.
