I really enjoyed reading about your system -- I have had an affinity for Tandberg stuff since I aquired a 3300X reel-to-reel as an early teenager. I used it with an outboard dbx noise-reduction box and was stunned with the performance - at 7-1/2 ips it rivaled an early DAT machine I got years later. At the time a dream system for me would have been yours - especially with the addition of the TD-20.
I also spent several years as service department manager of an audio store that had sold Tandberg for decades - the owner had even been to the Tandberg family residence in Norway. I worked on all of the 3000 series stuff, and the older gear too . . . seeing it from the inside is even more impressive, especially the 3014A.
If you're ever in need of Tandberg service, I had a very good experience with Nick at High-Tech Electronics Labs in New York, (212)768-0960. He did a couple of head replacements and alignments on reel-to-reels for me about ten years ago, and the results were stunning - good enough for me to keep his name in my Rolodex for this many years.
