John Tracy's Creations
"Well, it had to happen. One of the last open pieces of 'real estate' in the Mood Indigo has been 'developed'. It went to make room for a choke, used by a new, higher voltage negative supply." Those are John's words - I don't believe that it is finally full - John is so creative at packing in just one more feature.

And here are some pictures of John's Sun 2A3 amp that he recently redid. Visible are a pair of LL1690 input trannies, CCS plate loads for the input and driver stages, Kevin's stepped attenuators for volume and balance, one of the four LEDs that now bias the input stage and an added filament transformer to handle the 6BX7GT driver that replaces the stock 6SN7GTA. Included are before and after pictures.

I have given up thinking that John can't fit another thing in his Mood Indigo chassis. He was one of the beta testers for the RAKK dac Mark III and here is the Mark III along with a RAKK I2S Interface Adapter installed in his Mood Indigo. John is using the I2S Interface Adapter to connect his PS Audio PWT transport.

Just when I had thought that John had maxed out his Mood Indigo, he trumps his earlier efforts. This version uses a differential series-feed design with Lundahl LL1689AM output transformers. As a mark of John's building experience, this took 40 hours in a marathon three-day weekend. Congratulations again for a great piece of work John! Thanks for sharing it with us.

The Mood Indigo is a first-generation Raleigh Audio line stage based preamp. While it is still one of the finest preamps to be found, the electronics is not quite up to today's generation of the Extreme Active Output. John has taken his Mood Indigo and hypercharged it with the latest Extreme Active Output and added a RAKK dac Mark II to boot! It is truly maxed out. Congratulations on a great piece of work, John

These are earlier pictures of John's RAKK dac with Passive Output and Tent Clock. John updated to a Mark II and then moved the Mark II into the Mood Indigo shown above.

And here are some pictures of John's rebuilt Eico HF-89. His upgrades include a K&K Audio constant current source among other things.

John's craftsmanship is evident in these beautiful differential parallel 6550 mono-blocks that he built.
