We found out that it's not capable of driving the head flat. It provides EQ, the NAB or CCIR curve, and it's also providing EQ for the non-flatness of the record amp. We are now going right into the front of the final buffer before the EQ stage of the record amp. We have changed the EQ stage somewhat. But as it stands, once you get rid of the ground loops and hums and so on, it's quite a remarkable recorder.
People can judge that themselves just by hearing the record.
It's Performance Recordings pr7lp or pr7cd , released in October last year. I think it really degrades the sound. Well, we took our reel of tape made on the Magnesaurus over to Doug Sax at the Mastering Lab, and we played it back and measured things. Their standard mastering playback machine, the one with the preview heads, has its own custom tube electronics, which Haselton also designed. Very impressive, considering the changing tension.
