Sony Reel to Reel TC Tape Deck Microphone Input

Sony Reel to Reel Tape Recorder. Microphone Input Behemoth of a Tape Recorder from the 69-74? Loads of connections and features. Tape doesn't seem to work with NAM captures from what I have read. So, I had a go at the Microphone inputs, there was a surprising amount of gain available so its gone from subtle to not Drove the Mic Inputs at different levels for some NAM Captures The Inputs were a bit noisy On the first batch especially when pushed higher. So theres a batch of de-noised versions as well, Its cleaned them up quite well this time but see what think... Also tried a couple as sweeps rather than pairs see if you can tell the difference ?! Photo from manual till I get one sorted ....
