Quick backstory. A friend/client in my area operates a popular recording studio, and we've been discussing numerous details for a new "B room" in the building. This space will be mainly used for demo recordings and perhaps rehearsal space, but also will have links to the "A" room via line and mic level tielines in/out of patchbays. Future plans may include additional recording/mixing rooms as well.
The "B" room will have a Yamaha PM-1000-16 desk, and the various recording possibilities requires me to add direct outs from the input modules. One solution is clear to me, and that is to use a 1:1 output transformer for each of the 16 modules' outputs in order to ensure galvanic isolation to whatever may end up on the lines throughout the building. (We can all argue about using THAT balancing chips, impedance balancing, etc. in a different thread.)
The last stage in a PM-1000 input module is fairly beefy, with the same circuitry (except for size of the output coupling cap) used for the group outs which drive 1:1 Tamaura (IIRC) iron. Hence, plenty of moxie to drive 1:1 iron from Edcor (at the low end of the price spectrum) through Cinemag in the middle up through Jensen at the top end of pricing.
While pondering, I recalled the Ed Anderson iron sold by Jeff at Classic API. It appears to me that an EA-2623 with both secondaries wired in parallel could be an excellent "in the middle pricing" choice.
