Peerless S-217-D Clone Pultec Tube Output Transformer by ATC Frost NOS

This is a brand new recreation of the peerless S-217-D tube output transformer used on the Pultec EQ. These are made by ATC Frost, and were a limited pre-production run. I got them from a former ATC Frost design engineer who worked on their development and saved them from the scrap heap as the company chose not to pursue production. He was kind enough to run sweeps and provide data on each one so I can provide the matching charts with the purchased unit. Response is flat +/- 1dB from 10Hz-70kHz.
