Right,

I got somewhere. Replaced the 2SC454s on the record board as well, so all caps on the REC board and all transistors apart from the Rec output ones are new. All legit Hitachi ones.

The recording at 7 and a half is stunning. Bass response is good on all 3 speeds. however one last thing to make this deck 100% is the high end at 3.75 dies off MUCH earlier than my 4000D. You can tell from the stressed 'S' ess sound where it is not there on any of my other 4 decks recording at 3.75. It plays other tapes recorded at 3.75 perfectly without the stressed high end. Or do GX heads just have a worse signal ratio compared to perma alloy heads at lower speeds?
