We finally finished our WE300b based tape playback amp for Studer A80. This completes the signal path from microphone pre-amp to tape playback using basically all NOS 1956 Western Electric tubes! (WE437a & WE300b) The only non Western tubes are the Red Bank Bendex 6900 in the record amp for the Studer. Everything in this signal path is executed with all silver transformers & wires.
This doubles as a line stage for my TV system.
In "Tape Playback" mode, the volume pots are not in the circuit for absolute purity.
On 1st listen, the soundscape is indescribably natural with a quickness and freedom to transients that is very very close to the real event. On listening closer, the micro and macro dynamics are enormous, timbres and high frequencies of violins and pianos are totally resolved, but do not draw attention onto themselves... it's just there...
This is the collimation of all the thinking that went into building my audio system, described here: https://positive-feedback.com/audio-discourse/ultraanalogue-recordings/
